I am almost ready to test run the 20b but i am a little unsure which are the fuel feed lines and which is the return line.
the very front one i know is the one that goes to the charcoal canister, and the one next to it, if it is the same as the 3rd gen rx7 would be the feed line but i am not sure.
if anyone knows please reply asap, i am getting
excited about starting it! can hardly wait!

thanks

the feed line is the one that goes to the primary rail.

ok on the 20b is the primary rail the upper one or the lower one? I am assuming its the lower one.

matt

 

yup its the lower

that is the way i had it connected and it wouldn't run, no fuel, i will check to see if the injectors
have power getting to them.
looking at the wiring diagrams it almost looks like the upper is the primary, but its hard to
tell for sure, i guess i can check wire colors to find out for sure.
