just swapped my old motor back in after a complete rebuild. though rebuilt, i keep it stock with the exception of valve springs and retainers. i still have the walbro 190lph that is still being used from my old setups. the problem is that my fuel pressure is sitting at 64-68psi while at idle which is way high.

Things i've tried: changing fpr(one stock, one adjustable), changing fuel gauges.


car: 92 cx
motor: B16A

has anyone expierenced this before?

 

check the return line for restriction, try to pass air through it, it should be free flowing

 

will do so, thanks... funny thing is, everything was reused from the old setup.

 

cleared the return line, no dice.

i placed the return line in a bottom and primed the system, fuel came out as it should. also, when i unplug the return line, the hardline from the chassis spilled some fuel out so it seems to be clear from debris.

any other inputs?

 

kinked a line when you did the swap? check your lines. just a thought. good luck man.
