ka fpr onto a sr???

[supreme_1]

does anyone know if the Ka-de or ka-e fpr will fit and run my sr perfectly?

also is the fuel pressure from a ka the same as an sr?

[S14DB]

It will fit. Are you using a stock fuel pump?

[Sileighty_85]

well the KA FPR with Vac connected is 2psi lower then the SR's
Vac Connected= KA 34PSI,SR 36 PSI
Vac Disconnected= they are both 43 PSI
FSM recommends that pressure is maintained at or above that level
But if running a Walbro FP it might kick it up a few PSI so you should be good

yes i am running a walboro 255 fp

during key on position i can put my hand on the inlet and i feel fuel running straight through the lines (this is without the car running) for as long as the key is on, not just priming. could it be possible that the walboro is pushing too much fuel through the line thus the pump is faulty?
