Stock TBI fuel line configuration? Can someone snap a couple pics for me?

[Ed Gein]

I bought new stainless steel hard lines for my build, but Inline Tube doesn't send any documentation with their kits.

The old fuel lines are long gone.

I'm trying to see how they are routed along the frame rail. Can someone help me out here?

This is what I'm working with:

I am not sure how much help I can be, but I just got done removing and re-installing the fuel lines in my pick-up (TBI saddle tanks), which make the fuel line lay out half the same as yours. From What I see of your pictures you have them in correct. The main 3/8" fuel line runs down the middle, the 5/16" return line runs along the top, and the 1/4" evap canister line runs along the top. Unless that 1/4" line across the top is a brake line. A brake line runs across the top too.

Correction: Evap line across the bottom.

If you need an area clearer, let me know.

Because you have never messed with your lines since from the factory, I am going to use your picture against my current fuel line lay out to double check my fuel line re-install. Your fuel lines from the filter to the engine are the same as mine. I re-routed my evap line slightly different than yours because of new longer rubber fuel line I installed. Good job on the pics.

Yeah, I'm pretty sure nothing has been messed with since it was built.

Thank you so much. That's exactly what I was looking for. I've spent hours on google searching for what you just posted. I went to the local junkyard to get some pics, but they hardly have any square body stuff anymore. The IFS trucks have taken their place.

I'm going to throw some keywords in at the bottom, to help others find this while searching the internet.
