NA 1.6 FPR question
 

Hey guys,

putting a K24z3 and eventually a turbo in a 90 Miata. I have to use an FPR to make it work with the return style system. Would I be able to run a line to the FPR, then run a line to the rail, keeping the return line on the FPR? So eliminating the need to run a line to the rail, then from the rail to the FPR, then to the return line.

as seen in this photo only one line goes to the rail.

Yes, assuming that’s hooked up correctly, that’ll work. Lower port should be factory return, side ports should be rail and factory feed, doesn’t matter which is which.

thank you much!

If you haven’t seen this yet, should. Stefan is very meticulously and would I’m sure be happy to answer any questions. I believe he had one of the first running z3 turbo builds.

Yes it can be run like that. It's called a dead head style fuel system. A real return style (flowing through the rail) has some benefits but honestly the guys running dead head systems don't seem to have many issues with it that I know of.

I'll be running mine return though, so Feed -> Filter -> Flex Sensor -> Rail -> FPR -> Return.
