On HP, the config of the engine I'm running (418 cu in) dynos at 621 HP at sea level. I'm up at 5400 ft so I expect it to be around 520 or so using simple formulas that don't account for the engine setup in any way. I am planning to run a fuel filter. I'll actually have 2 in the system, a 100 micron pre-filter on the pump in the tank and a 10 micron post filter somewhere. I still need to decide on the mounting. The filter is rather large because it is rated for plenty of flow. I am running 3/8" hard line and -6 flex line. The 3/8" lines are plenty for a high pressure EFI application and could easily support over 1000 HP. It's the pump that makes the big difference and the fact it's a 58 psi system vs a 7-13 psi system. My estimated psi loss is right around a touch more than 1 psi so not much on 58 psi but huge on a carb'd setup running say 8 psi. Hence why it's best to run the regulator as close to the fuel delivery system as possible, since the pump will "compensate" for the pressure loss. If the regulator is right at the tank and fixed at say 58 psi, then the injectors could very well only see 56-57 psi. Depends on the injector whether that matters or not. Most likely not for a street car. Race car different story. Here's a shot of the rear line setup a took awhile back when I had the tank still in the chassis and went ahead and made those lines. I have yet to mount the filter. Where I want to mount the filter requires $300 in tools since I don't have a 37 deg flare setup and I've only found one that looks worth while (The Eastwood bench mount turret style one). But I do have a shot of the filter and regulator in a previous post (ignore the Option 1 as I'm just linking straight to that photo from that post). Here's where I want to put the filter. Basically redo the junction there and insert the filter. But I don't want a bunch of flex line down there so I was going to just bend the hard line and put some fittings on to go direct to the filter. I currently have AN fittings, but I need to see if there are some other options since the filter just has a -8 o-ring thread on the ends. And here is the shot of the rear fuel line termination. Rob did his slightly different on 'Goldie' which he's building right now for himself, but otherwise the same.

Thanks for the great explanation. I am in the middle of doing the fuel filter as well. A lot of choices and tube end options. Not sure about running either annealed stainless, aluminum lines or maybe what you ran. I see that you used the green copper variety of line (dont know the name of it). |

Thanks SCOTI! It was a mission to get to this point.

And I had a little fun with the GoPro today and took some video footage of the headers a little closer up for a better look.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
.......my vote, put the regulator and filters on the frame. Keep the firewall clean.

Where would option two be for mounting the regulator?

Option 2 is putting the regulator at the back of the fuel rails. At the time I made this photo (linked back from that post #34) I was thinking of attaching to the firewall, but today I'm thinking of fab'ing a bracket off the back of one of the cylinder heads and keeping the regulator as low as I can. Although I am looking at a frame mount option as Trackman101 suggested near the front of the engine on the passenger side.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Mounting it to the back of the motor is a good idea. It's a nice piece.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Hey Chris
How did you run your back brake line? Where did it start, and did you run the line to the rear end by a flex line and then out to the calipers or on the chassis rear cross member and then pierce the chassis with a bulkhead through the frame, and then flex lines to the caliper? Any pics would be great. |

Those headers are a work of art...matching the looks of the engine overall. Well done! I liked your video too.

Here's a shot of the brake line bulkhead up front. The green tape are the -3 AN fittings. The front one is the front and rear one the rear. Here's a shot showing the rear. The green tape in front of the coilover is the -3 AN fitting for the flex line. Thanks Doug!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Thanks Chris for the explanation. Rob does a great job. You can tell by your chassis. Everything has been well thought out. I have his front and rear suspension also. I like the idea of piercing through the chassis instead of having the lines attached to the axle.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Ok, Trackman101 was the tipping vote on the regulator. Some 2" 3/16 bar stock, cutoff saw, grinder and welder and BAM! - the start of a bracket. Here it is in the ugly state. I still need to trim the corners and other shaping to make it look a little more respectable, but it serves the purpose. Excuse the temporary hardware. It's what I could find laying around.
Drilled a couple holes after cutting a section off of the bar stock. Here it is after cutting and welding. Still need to trim the corners and make it a little nicer to look at. This thing may wind up serving double duty - if there is enough space on the backside that's where I plan to mount my fuel and oil pressure sensors. So this thing could kill two birds with one stone. With the air cleaner on it's not even visible from this angle. View from the driver side.

Thanks John! I can't wait to start "abusing" my ridetech HQ coil overs and putting them to the test.

Hey Chris
Where are you planning to mount your battery and running your cables (chassis rail and location on the rail?. |

I've also toyed around with putting it in the cab behind the seat if there is enough room (I plan to mock this up in the coming weeks). No matter where I put the battery, I'll have a large junction over on the driver front side where I'll tie the alternator in and then also the relays for the fans and the power for the fuse box. So I'll at least have a monster cable running over there. I'll then obviously have a monster cable running from the battery to the starter. That's still all up for debate at the moment and one of the reasons I haven't patched the 2 feed through holes in the floor from the old gas tank. I'll still ground everything to the chassis. Cable routing I'll just use some well insulated cable (pricey stuff) and some of the standard insulated cable hangers you get at the big box stores (that stuff works well). The battery cable would most likely run along the passenger rail with one of the fuel lines. Sounds crazy, but look at a newer car and where they run the battery lines and not much different, other than some of those battery cables are scary huge. So stay tuned on that one!

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Got the fuel filter plumbed up last night, but not mounted. Bent the existing 3/8" fuel lines and cut up the front section a little to fit the filter in. I left the double flare union so I have a short length of line I can remove in order to get the filter out without having to loosen the whole fuel system up. My trouble now is I need a compact drill to get into the chassis between the rail and center bridge to drill and tap the holes for the filter mount, but all I have are giant old school 18v DeWalt drills! They are almost as long as that area is wide! Doh!
And I may wind up needing to make a heat shield since this filter is so big and I'm guessing will be about 1-1.5" from the exhaust pipe. TBD on that, but some thin 26 ga steel will do wonders to keep the heat at bay. Here is a before and after shot showing the whole area I modified. For reference the before shot is linked in from post #104. A little closer up on the front section. After cutting the front, I made 4 bends to get the tube to hit the filter. I used -6 hardline fittings (with a 37 deg flare, not the compression ones) to hook up to the filter. A little closer on the back. I only put 2 bends in the tube otherwise didn't do anything else. Just flipped on the one clamp you see there. The other side of the union (filter side) is just the portion of the forward section I cut off, not mod's here. I got lucky that it lined up so I left it all alone.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis
Thanks man!
And I went and picked up an air drill to finish off the mounting. So that's all done now ... Just showing why I left in the union to remove a small section of tube, let's me slide the filter out of the housing.
