Gas tank relocation

[57chevyman]

I know this has been discussed before . Can someone give me a link to a good thread on this subject ? I still have the tank in the cab. I know I've heard that old mustang tanks fit under the bed.... Do you get a reproduction mustang tank? If I can afford a new aluminum tank is that better? Sending unit that works with my stock gauge? Electric fuel pump ? Do I bypass the mechanical pump when using electric pump?

[Rickysnickers]

Here's one thread, http://67-72chevytrucks.com/vboard/s...ank+relocation

The only question I can answer is regarding the pump. If you use an electric pump, then you do not need a mechanical pump. Get a block off plate, over the boss in the block, where the mechanical one would go.

One suggestion. If you relocate the tank it may be wise to leave the original filler in place. It may help with resale should you ever decide to sell. When I bought my '64 it had the tank relocated under the box but the original filler was left in tact. I know in this case, I would not have bought the truck if the filler hole in the cab had been filled. Of course it's your truck and if you don't like the filler hole then by all means, fill it. Just something to consider.

Yes I plan to leave the stock filler hole where it is

heres what they have in the LMC catalog....i may go for this. can someone point me in the right direction with mustang gas tanks?

[57chevyman]

ive read in other threads that the 1970 mustang 22 gal gas tank is an inexpensive tank that fits the 1957 truck......
1969 mustang tank is 20 gallons.

is the sending unit for my stock 1957 gas gauge compatible with this tank?

but is the 1970 mustang tank supposed to be 18 gallons?

that sounds better than the $400 tank from LMC. although LMC makes it easy to order all the other parts that are needed that work with their tank.

That $77 mustang tank is a bottom draw pickup tube that has the sender integrated in it. So you would have to get a matching Mustang pickup.

Tanks Inc sells a top feed tank with a sender that works on GM 30 ohm stock gauges. There are 18 and 22 gallon Mustang tanks. The 18 is a better fit. You can get the Tanks inc tank with a standard pickup tube for a carb engine or get it for an electric pump.

If you get a stock mustang tank with a ford sender you need the buy a converter also sold by tanks inc to make it work with your gauges.

If you would like some pricing on the tank setup from Tanks Inc send me an email. I sell them in kit form so you don't have to hunt for matching parts. I just need to know where you want the fill to come out

thanks, i sent you an email

I'm going to get a tank from tanks inc.. It's like a late 60s mustang tank, but with the feed on top , not the bottom like a stock mustang tank. The kit comes with a sender that works with my stock gauge. Planning on making a flip down license plate bracket and have the filler cap behind the license plate . Anyone here have this setup in their truck ?

[lowrodderchev]

I used a 64 mustang tank drilled the top out for a Chevy sending unit so my gauge is hooked up ran a boat style filler in my bed

[57chevyman]

I like the idea of hiding the filler behind the license plate . I'm gonna leave the stock filler cap on the cab

[Rude Dude]

Here is some pic's of Industrial Chassis Inc. in Phoenix AZ. Steve there used a ford tank and filler at the back. If you look at my build I used a Mustang Tank.

man I like that one a lot

[Rude Dude]

I think the tank lends itself well to Task Force trucks because of the shape of the bottom of the tank that's why I went with it. It doesn't hang down looking at it from the rear like all the other square aftermarket ones or Chevy blazer tanks.

thanks for the pics. love it. thats what im planning to do. right now i have a trailer hitch welded to the frame that needs to be cut off. i also have my dual exhaust there.. probably have to move the exhaust too. if the exhaust hangs below the gas tank, how much clearance does it need so the heat isnt an issue?

[Rude Dude]

I will be running my exhaust out the sides exiting below steps. When I get to that point I already mocked it up so it is not an issue, but I did see a truck build in classic truck magazine with the exhaust ran over the axle on the outside of the frame to the rear so that would be okay. Try going to the magazine site for reference, the same truck in that build is the one showing the front runner A/C system from vintage air.

Here's what I did for my 3200 89" long bed:

It's from Tanks, Inc.

http://www.tanksinc.com/index.cfm/pa...prod/prd73.htm

It's perfect for those that don't want to fill from the bed.

What I did for my fill was to cut out the original flange in the cab and found a place on the rear fender with a similar curve and welded the flange in there.

















I also tucked this tank in up as high as I could for clearance:

just noticed you had to drill a hole in the rear sill for the gas filler..... nice setup you have.
i just got my tanks inc mustang tank.. not sure if i have to do the same to my sill, or if the filler will be just below it?

[AZ59apacheguy]

I'm looking re-locate my gas tank as well, but have one question. What is everyone doing about the metal bed strip mounting bolts? Roger55, I love your idea, but it appears you've actually cut into one of your crossmembers, what have you done about the metal bed strip mounting bolts?

[mr48chev]

Word to the wise from someone who has seen it happen. If you do leave the stock filler in place on the cab after moving the tank rather than filling the hole do yourself a favor and cut off the filler neck and weld a plug in it or put a locking cap on it and leave the key at home so no one has access to the filler neck. I had a friend get several gallons of gas run into the cab if his truck because a kid who borrowed the truck decided to fill the tank and yes, stick the nozzle in the filler neck on the cab and had gas running out the door. His tank was easy to see as it sat in the front of the bed with the filler neck sticking up for the world to see but the kid missed that fact.

Excellent point . I did imagine that happening . Probably switching to a locking cap is the best option

I would weld in the patch. If you do consider doing what I did, you will want to cut out the flange for re-use in the rear fender anyway.

Btw, I don't remember who gave the tip to me but it was a good one. Since I was putting in rear cab corners on this truck, the parts I cut off gave me a perfect contour to make a patch from for the patching filler hole.

[OrrieG]

Here is mine, 19 gallon from Yogies. Because of the fleetside spears the access is low and hose runs relatively flat so I will need to be careful when filling. The tank is designed for step side so cross sill needed modified, I beefed it up with 1" angle on the front side. Door is from a 90's Dodge caravan, chosen for the inside release and matching the curve of the bed side. Release is inside cab, POL had the sending unit with OHM value to match original gauge. Bolts to bottom of frame so I can remove without taking the bed off.

Yes, I cut that one bed cross brace.
You can see here that I welded it to the 2 pipes that are used for the tank mount. Those are standard 1/2" black pipe and are plenty strong so there's no concern there.

I will have to remove the tank when I install the bed wood. No big deal to me. There's still room for mounting bolts but I may have to trim the bolt ends off.

[Russell Ashley]

Not to change the direction of the thread, but for general information, that odd cross member goes in position three which is toward the rear of the spring. It seems to be a common mistake to put it over the axle in position two.
