hey guys I have a s4 chassis with a s5 t2 engine that I want to run stainless fuel lines for I want to run them the easiest way possible, can anyone share their build threads so I can get some ideas and possibly line size and fitting size

 

I did a budget easy fpr setup for my s4t2 lines.

I'm not familiar with s5 t2 rail, but I remember a lot of people using s4t2 rails

The factory steel hard lines are 5/16" . steel braided or lines for -6 would be 6/16=3/8". My buddy told me he used to just put 3/8 fuel line over his 5/16 hardline and just clamp it and not have problems. I stuck with the 5/16 fuel line though

 

I'm also using the rising rpm rails

 

and I also want stainless lines all the way back to the tank if possible

 

See the Aeromotive power planner. Note that the suction lines are one size larger than the pressure lines. Since your engine has two fuel rails, you can either run them in series similar to the OEM setup, or you can use a Y-block and run them in parallel like you see on the A1000 EFI system example.

For long stretches of fairly straight line you will want to use hard line because flex line will sag like Christmas lights. Tube nuts are available to mate the hard line to the braided line, and some vendors include them with the hard line. Note that fuel pumps and filters usually use ORB fittings, so be sure to check for that before you buy parts because this is going to be expensive enough as it is without errors. For tools, you will want a tubing bender, hack saw or abrasive cutting saw (although some people use a chisel to cut flex hose), aluminum AN wrenches, a vice, and AN fitting vice jaws. Components and tools are available from online stores like Summit Racing, Jeg's, Racer Parts Wholesale, Pegasus Racing, and Aircraft Spruce. You can find how-to videos on Youtube.

If you don't know how to lay flexible hose, below is a link to a general primer on the subject. Each brand and model of hose will have a minimum bending radius, so get this information from the manufacturer to make sure you don't over-bend the hose. Also note that braided hose that moves or flexes will cause abrasions on anything that it touches, so keep that in mind.

this will get expensive















Aeromotive stuff
Earl's performance lines and fittings
Walbro pre pump
bosch 044 main pump
fuel rails connected paralel

also kept the option to run another line along the other side as a return line, that way I can convert the system to a dual pump and feed line if that would be necessary sometime
