one the frame before the selector valve, which fuel line is the feed which is the return top/bottom. i used the searchy thing but that was no help. TIA
If you can tell the difference, the smaller line is the return line and the bigger is the feed. On the selector valve there are also markings, but they're usually almost impossible to see.
i went ahead and cut the top one...if i messed up and its the return ill just fix it and use the line i guess i was looking for some assurance on which line to cut
