Fuel line recommendations
 

72 LWB LS swap tank behind axle and I Need recommendations how people have done the fuel lines? Braided stainless or solid line with short braided stainless at ends?

Re: Fuel line recommendations
 

Ill be installing all braided stainless on mine in a couple of weeks

Re: Fuel line recommendations
 

As much hard line as you can run, then braided hose for the final connections to moving parts.

Re: Fuel line recommendations
 

Hard line steel,stainless or aluminum? 3/8? LWB or swb? How much?

Re: Fuel line recommendations
 

Depending on where you live you might want to get PTFE lined hose for your braded stuff. Some of the additives in gas will eat through normal braded line.

I used the ptfe braided line for mine

I used the newer NICOPP tubing (nickel+Copper+Iron) on one of my projects. Really easy to bend and it will not rust. I bought mine from this guy:

Best price I could find at the time. It bends really easy and flares easy with a regular double flaring tool. There are coated flare nuts available for it too. Some of the auto parts stores carry it but it is more $. I don't know how it would do with the AN6 tool.

Steel imo.
3/8 feed, 5/16 return if you need it. I can't tell you how much, that depends how you route it. Protip: buying a 20ft roll of 3/8 steel line is the dirt cheapest way to get it, and its very handy to keep around the extra, as you WILL mess up somewhere.

Technically any of the hardlines will work, however if you plan on using the hardline-braided line AN tube adapters, you need to be careful with the softer options like the aluminum, or the very hard like stainless.

Soft lines can get over-bitten by the fittings, and can chafe or puncture from repeated bending (which happens if you don't have properly designed braided/hose sections to absorb the movement).

Stainless lines are harder than the ferrule in the fittings, and sometimes it means the fittings don't get a proper bit and seal on the line. This can cause a little leaking from the base of the fitting.

I agree with brew in regards to the hard-line.

I ran braided from the sump to the pump and to the frame-rail. Then hardline up to the engine where I split it off in braided again to the back of the fuel rails.

Whats the Y in the supply for? Nitrous enrichment?

Re: Fuel line recommendations
 

Reduced from single -10 to dual -8s to feed the fuel rails.

I also did the return line in hard aluminum, up to the flex fuel sensor, then went braided back to the tank.

Re: Fuel line recommendations
 

Is there a flow advantage to doing it that way? I've looked at a few aftermarket rails setups for if I switch my intake off, but I usually see it fed from PS and then to a crossover, with the other rear port being a return.

Where does your return exit the rail?

Re: Fuel line recommendations
 

Wow didn't pay attention to that thanks for the web site and hope you got that taking of LOL hehehehe

Re: Fuel line recommendations
 

I run dual inlet and outlets to and from the rails because I feel that is the most balanced setup.

This is also how Aeromotive officially states that a dual fuel rail, return style fuel system should be plumbed.

This is how it used to run.

This is how it runs now. Hard line out of the rails to the regulator, then down to the frame rail.

Cleaned it out.

Re: Fuel line recommendations
 

hows that new Holley hi-ram (that what they cal it?) intake working out for you? I've been eying that one for some time now.

Re: Fuel line recommendations
 

Not speaking for him, but I know a few people with it who LOVE the thing...IF you got hood clearance for it. Its one of the highest flowing intakes without going to a single plane and all that jazz.

Re: Fuel line recommendations
 

Yea, it's working pretty good for me, and looks outstanding. I had planned on running the sandwiched A2W core from my bud Blake, but it wouldn't clear the doghouse on the firewall of these trucks. At least mine wouldn't.

Anybody use this stuff yet http://www.speedwaymotors.com/Black-...6-AN,8976.html

I'm sure some of you have seen the parker push lok that sloppy mechanics uses but this actually says fuel line. I wonder if it is any good. Speedway says you can run alcohol and diesel through it too.
