Re: It’s Just A Pickup
 

Where do all the tubes go?
The tow hitch and fuel tank plus aft fuel lines are installed.

Cleaned and applied a coat of Dupli-Color professional undercoat and sound eliminator to the Blazer style fuel tank. That stuff definitely needs a few days to dry before installing the tank. If you’re interested in how the tank was installed check out an earlier post on this build (post #252) http://67-72chevytrucks.com/vboard/s...318544&page=11

Might not be the best location for the vent tube high loop, but it was the best place in my mind to incorporate one. I’m installing a vapor/charcoal canister for venting the fuel tank and a vent tube high loop is needed to prevent any liquid fuel that might get into the tube from getting to the canister. Since the vent line will be exposed in the wheel well I put some ½ inch air hose over it to help prevent damage to it. Yes two holes where drilled in the frame to run the vent line out to the wheel well and back, plus some short chucks of fuel hose to compensate for bed flex to frame.

Then onto the bending and fitting the vent and fuel line to the front. I’m using 3/8 inch aluminum tube for the vent line and fuel line. This tube can be found at Summit or Jeg’s in bulk coiled up form. When I was down at the auto parts store picking up a few feet of 5/8 fuel vent hose the parts man ran back and cut me a chuck of heater hose and I had to explain to him that it would not work and after looking in the back came back with some 5/8 fuel vent hose (Watch out for what they try to sell you they may not know). I’m using the 5/8 fuel vent hose for the filler vent.

Fabricated a mount for the mid fuel fill tube from some 4 inch x 4 inch x ¼ inch angle iron and bolted it to the frame. Then used a SS exhaust clamp to mount the tube to the bracket. If your interested in the mid fuel fill tube design check out an earlier post on this build (post #76) http://67-72chevytrucks.com/vboard/s...=318544&page=4 . The upper fuel fill tube and cap is a LMC 29-3470 Fuel Filler Neck and LMC 32-4129 Gas Cap Non Locking that are for a Chevy S10 (94-95 pickup) I did cut the tube down to 2 inches below the vent tube.

Attachment 588502

Because there is a long span between floor cross sill supports I’m adding a short cross sill just forward of the fuel tank (There was no cross sill at this location on the stock bed). Also I’m installing a custom cross sill over the fuel tank for clearance and floor support. If your interested in the custom cross sill design check out an earlier post on this build (post #106) http://67-72chevytrucks.com/vboard/s...=318544&page=5 .

I’m a definite advocate of grounding all fuel tubes for safety. I’ve had a fire from a static spark from a bad ground when refueling a helicopter and that fuel is less volatile than gas.

Attachment 588503

Since the fuel tubes are very close to the wood floor and wanting a little cushion for the bed to sit on, I’m raising the bed up a slight amount. I have a 3/16 inch thick bed mat that I cut some 3 inch strips from to use under the sill to frame mounts and along the frame cross member (The wood floor sits on this cross member normally).

Attachment 588504

The one tool that you normally don’t see in a shop is a tube beading tool. You know that raised area at the end of the tube that you slip the hose over, it’s called a tube bead. The tube bead can not be formed with a flaring tool it requires a special beading tool and most beading tools cost $150 to $200 and up.

One low cost tube beading tool that you might consider is Earl’s Performance, EZ Tubing Beader, (tool number 008ERL for 3/8 aluminum tube) aprox cost $30 , you can find one at Summit Racing. There are some limitations with this tool, like it’s only for aluminum tube, it only works on 3/8 tube, the bead that it creates is not as high as a factory tube bead.

I’ve used this tube beader for years and found it beneficial when making my own fuel lines maybe you might find a use for it too. Hears a step by step how to use one

Now that I’ve exhausted you in a long post (sorry) no not really (smile) Enjoy your build

Re: It’s Just A Pickup
 

Boeing misses you Bruce.

Keep up the good work man.

Re: It’s Just A Pickup
 

awesome work!!

Re: It’s Just A Pickup
 

Your attention to detail is going to make any new factory truck look shoddy! Very nice work once again Bruce!:metal:

Interesting beading tool you 've got there, I always use double flare for fuel and brake lines. Is there anything wrong with that?

Re: It’s Just A Pickup
 

For brake lines double flare it’s the safe way to do it.

The beading of low pressure/vacuum tubes is the common approach when slipping a rubber hose over the tube with a clamp. Some times you will find fuel line fittings that will require a double flare to connect the tube. I’ve put a hose with a clamp over a double flared tube and it worked but the double flare was not designed for this application. The tube bead gives a raised smooth surface for the hose to seal on and help prevent the hose from slipping off. The double flare isn’t as smooth and not designed for a rubber hose to be used. If I was concerned about the hose sealing or coming off under pressure and the tube had no bead I would push the hose a little further on the tube and use two clamps.

Hope this answers yore question for you

Re: It’s Just A Pickup
 

Great looking progress and as always very nice detail explainations! keep it up!

Re: It’s Just A Pickup
 

bruce i had just bought some of this to use on the underside of my cab "Dupli-Color professional undercoat and sound eliminator". do you recommend it or should i save my money and return it? the reason i had bought it was cause it said you could paint it, let me know what you think, thanks.

Re: It’s Just A Pickup
 

Paint and finish are one of my weak points (limited knowledge areas) but Ill give it a shot from my point of view.

I had no concern about the gas tank rusting since it’s similar to galvanized metal some might call it pickled. I just wanted it black and a little sound deadening, the Dupli-Color definitely needed a few days to dry, as far as painting over it I don’t know it says you can. It would probably work for under coating a cab.

My personal thought on undercoating a cab is I plan on using bed liner material that seems more protective and durable than the Dupli-Color undercoating and think you might want to look into using a bed liner material.

Re: It’s Just A Pickup
 

Great, thanks! Just what I was looking for!:uhmk:

Re: It’s Just A Pickup
 

that is what i ahd originally planned was tptools raptor bedliner but saw this stuff and thought i would give it a whirl. iam glad i did not spray it yet though, i will go back to plan a. thanks again bruce.

Re: It’s Just A Pickup
 

Mainly this is a test to see if I can post two pictures side by side instead of on top of each
other.

I just finished up running the fuel and vent line to the front of the frame. Then set my
camera inside the LH frame and took some pictures of the fuel and vent line run on the
RH frame. Definitely a point of view that you would not be able to see when the trucks
complete. Stitched the pictures together to give a flat panoramic view of the run from the
front to the back of the truck. The stitching is not the best because the lighting wasn’t that
good and the color shifts with the flash from one picture to another is very noticeable.
With the width limitations on the forum posts thought it would look better size wise with
the pictures side by side to tie the run together. So I’m giving it a try

Attachment 590081Attachment 590082

Hears a standard picture of the run

Attachment 590083

I always like to try new and different approaches to things sometime just to see if it can be done.
Well it looks like it worked

Re: It’s Just A Pickup
 

very cool point of view. Great reference item. Your build HAS to be an FAQ when completed.

How to do a frame off.....the right way! :chevy:

Re: It’s Just A Pickup
 

sweet work Bruce

Re: It’s Just A Pickup
 

Finally the shop statue/artwork has found its final home and where it should be to show it off.
After to long a time, the engine and transmission that’s been sitting in the corner under covers have been married together and installed.

Not a lot to say about the installation, it was just slipped in and bolted down. I did use a CCP Trans Crossmember, part number CP9427 for the transmission mount, moved aft approximately 3 inch’s to accommodate the 700R4.

Now onto the exhaust system installation, I’m going to be installing a Magnaflow exhaust system. Enjoy your build

Re: It’s Just A Pickup
 

looks good . 3" is that going to be a problem with the distributer hitting the firewall ?

Re: It’s Just A Pickup
 

Looking great....pretty sure he was just speaking of the trans mount being 3" further back because the 700R4 is 3" longer....
the engine looks to be in the front two of the three holes so he'll have plenty of firewall clearance.

Re: It’s Just A Pickup
 

The engine is in the stock location, it was just the transmission crossmember that was moved aft to accommodate the 700r4, so there will not be a problem with the distributor hitting the fire wall.

Re: It’s Just A Pickup
 

Bruce that is still something to be proud of! You have so many details coming together that everything you build or install just makes it that much more unique to your build. Very nice job!

Re: It’s Just A Pickup
 

Great work as always:ito: I really love the details on the frame and tubing.

Re: It’s Just A Pickup
 

More rework than it should have been to make it fit
When installing the exhaust system things that should not have been, cropped up

Some exhaust kits bolt right in with minimal trouble this one by Magnaflow is not one of them. I can’t expect the kit to compensate for modifications made to the truck like using a 700R4 Trans or the rear gas tank location but there where problems that should not have been.

I’m using ram horn manifolds with what I would call a 45 degree angled back 2 inch dump on both sides of a SB Chevy and wanted some stainless steel down pipes from 2 inch to 2-1/2 inch. There where no down pipes made for our truck that I could find so I went with some DGU15S by Pypes stainless steel down pipes that I thought would work with minimal modification. The only modification that was needed was to bend the RH down pipe up another 10 degrees and they worked good with the top of the pipe running parallel with the bottom edge of the frame rail and cleared everything.

One tip that you might find useful is to use some plain nuts and washers for the entire test fitting of the down pipes, just lightly snugging them up till everything is set. Saving the self locking nuts until everything is set and ready for 17 foot lbs final torque. You don’t want to wear out the self locking nuts or seat the manifold gasket more than one time.

Onto installing the Magnaflow 2-1/2 stainless steel exhaust kit (part number 16643) for a Chevrolet Truck C10 Pickup.

Moved the exhaust X pipe aprox 2 inches aft to clear the transmission pan and give access to the trans pan if needed in the future. I shortened the aft end of the X pipe aprox 2 inches and this caused the pipes going up to the mufflers to just clear the swing arms by 3/8 of an inch on both sides. Like to see a ½ inch or more clearance but can live with the 3/8 inch.

Will be adding a ¼ inch shim under the trans crossmember on both sides to get a ½ inch clearance of the tubes.

Attachment 595808

From the mufflers on back the tail pipes where not going to work. All the pipe bends seamed to be right but their orientation to each other (clocked position) where totally wrong.

Not having any experience with welding stainless steel, did some web search for how to MIG weld stainless steel and the potential problems with welding it. Then brought in a friend that makes a living welding (he had no experience MIG welding SS either) and came up with a plan to solve the problem and minimize the MIG welding problems.

After cutting the pipe, TIG butt welding would be the best looking but I didn’t have a TIG welder to use and MIG welding a butt weld we thought would not be as good. So we decided to sleeve the cuts with a 2.5 inch sleeve, it would not look as good but will be solid and leak free.

After doing some test welds on some scrap metal, fine tuning the MIG welder settings for good weld penetration, strength and no cracking (each different MIG welder will require its own power and wire speed settings). Positioned each tail pipe peace and marked for best fit on the truck (all welding was done on the bench after fitting). The sleeves were a definite aid in setting up the complete pipe run before welding.

You use a tri-mix gas for welding stainless steel and SS wire, the welder supply rented me a small bottle of the gas and sold me a small wheel of SS wire a definite savings to me since it was just a small job that needed to be done.

Included a picture of the welding with some MIG welding info for those that might need to do some stainless steel welding. Note the weld does not flow the same way you would see on steel and we where surprised that there was less weld splatter than steel.

Attachment 595809

Had to trim the frame on both sides about a ¼ inch for added pipe clearance but I think the tail pipes fit pretty good now.

The Stainless steel tips are from Heartthrob Exhaust part # ITD212SS Turndown Tips

Attachment 595810

The SS hanger strap and shim material will be hear in a day or two and the boxes will be history (smile) Enjoy your build.
