so basically the fuel lines off my chassis are a little tweaked, and i cant tell which is feed and which is return. in relation to the frame rail, which is which?
if it matters this is on a 98 s14.
thanks.

Yes, it does matter.

Feed line comes off the pump and return line doesn't.

17506Q- return line.

one in the middle should be the return

and one on the left (while sitting under the car, feet at the diff) is the evap vent line

line coming off the fpr is the return. one coming off the filter onto the rail is the sending.

That diagram only works if your lines are intact. It's best to go straight from the tank and follow the line to the front.

Feed is the one with the fuel filter. Not sure if you still got it or not.

was going to say the same, but to me that much is common sense.

If, I could not figure out which line was what? I would extend both lines, place each line in a bottle and give power to the pump.
or do this

What if I get the lines mixed up half way? Use tape every foot like breadcrumbs Hansel. J\k

its more an understanding of the system than common sense. most dont couldnt even identify the filter let alone know if it should be before or after the injectors
