Which fuel lines go where?
Does the sending line go on the line on the engine that is closest to the front, or the rear? I know which line from the tank is which, but I'm not sure about how they should connect to the motor. It would probably be easiest for someone with an S4 TII to look at which line has the fuel filter on it, and see which steel line on the motor it is connecting to.

the one off the fuel filter(feed line) should go to the forwardmost steel line.

It would probably be best for you to go to:

Cochran-racing.com


Click RX7 FSM..your series, then fuel and emissions.

I have a printed copy of the entire '88 RX-7 FSM (including turbo) but it doesn't say which line is which (unless for some reason I missed it).

For S4, Page 4B-6, in the emissions and fuel control section. Vacuum routing diagram..

Follow the lines!

OK... That might be why I never found them. I would have never thought to look in a vacuum routing diagram to find the fuel lines.
