Who can show me some pics or give some direction in how to most cleanly bring 2 fuel lines, supply and return, into the back of an EFI manifold?

Hi Jim, don't know that I have any pictures but what I did was bought two pre bent steel 3/8 fuel lines for the 67 and then cut off the ends. Then I bought some handy tube to AN fittings and used them to connect the braided lines to the steel. Then ran the braided lines in the back to the tank and the lines in the front to the fuel rails. In the front I installed a fuel filter on the outside of the subframe just before where the stock fuel line would make it's way back over the subframe and into the engine compartment.

You know, just because it's you....I could snap some pictures if you want.


In this pic, you can see the braided lines on the firewall...

I did the same thing, but I only used a single 3/8" line since my regulator is at the tank. I bought a new stainless line from Rick's, cut off the ends, and re-bent it a little at the tank and under the hood. I used Swagelok -6AN to compression fittings on each end. Everything between the ends is under/in the stock clips. You should be able to do the same thing with two lines--may need to replace some clips.

Sounds about identical to how mine is done!

[thedugan]

jim, there is a a guy over on protouring with a firebird that did 2 half inch lines front to rear. im looking for the link to his page that has some really good pictures.

[JimM]

Thanks for the shots, guys.
It's the underhood area I'm looking for, the rest is handled.
Anyone else?
Jody?

This is how mine may end up...my intake has space all the way to the rear, so i cleaned it up by running the feed, and return under it...I do have the lines in insulation wrap so they dont get heat from the intake.

They come out the back towards the pass side under the heater core, then to the subframe.

Dont have any pics of that though, sorry. I dont know what intake you have so you might not be able to do as I did...

do you have any problems for the fuel getting hot in the lines under the intake?

I cant say for sure, as I have not had the system on that long.
I have insulation that covers the lines under the intake, as I do for my power steering lines that run near the header.

I need more time to give you an honest answer, but I think it should be ok though...if they were not covered in the wrap, I would think it would get a little warm...i wanted a cleaner look, thats why i did the under the intake thing.

If It becomes a heat problem, then I guess it would be off to plan "b"!

I'm a big proponent of not bypassing the hot fuel from the rails back to the tank, so I don't mount the regulator up on the engine, it's at the back of the car. Then there's only one line up into the engine compartment, split with a "Y" behind the engine into the two fuel rails, with a balance tube from rail to rail at the front. In this pic there's no front crossover tube from the front of the rails, just a gauge in one and blocked off the other. You have to look hard to see the "Y" on the passenger rear next to the distributor, with stainless hard line feeding into the rear of the drivers rail, and a 45 fitting from the passenger rail to the "Y". Normally I put the crossover tube up front from rail to rail, but it worked fine without.

by the way, if you don't want the regulator in the back then at least mount it off the engine and before the rails, so the bypassed fuel doesn't get heated by the rails first. It will still heat up this way as the regulator is in the engine compartment, but not as bad as if it was after the rails. The fuel heating issue shows up on long drives, Power Tour is a perfect example. There were several cars stuck on the side of the road on a 200-300 mile daily drive from town to town, that had never had an issue before. Thing is, they only cruised around their home town in short spurts, and this was their first long drive time.

My setup, using a holley 4bbl TBI, has the regulator built into the throttle body. supply and return are 3/8" pipe thread, facing straight back, 2" on each side of the engine centerline. I'll need "tee's" with 1/8 pipe fittings for pressure gauge taps, and then work my way to the hardlines on the frame rail.

The most obvious solution is to run hardlines around and forward along the manifold, then braided flex from the water pump area to the frame.

I just loath the thought of sticking those pipes to the top of my motor tho...

why can't they go from the rear of the engine? If you want to tone them down use black braided lines and fittings. With the flex lines like above you can route them away from the exhaust, probably along the firewall over the headers under the heater box and then down to the frame. Plus the black fabric braided lines don't pick up as much heat, and you could add insulating sleeves for high temps for more protection, at least where they go over the headers.

Jim Jody's got the right idea for what you want. Run hard lines from the tank up the stock location then cut them and transition to braided flex down at the fram rail under the heater box and run the line up to the backside of the throttle body. Just make a bracket to support the hoses from the passenger rear intake bolt or manifold boss and not the firewall. This should still keep you legal to run at the track.

I couldn't copy a picture of your car to use so I used one of mine. It's kinda crude but you get the idea.
