just got a 93 hatch and it already had in it a B18B1 and a walbro 255 fuel pump and an adjustable FPR. what should the fuel pressure be at? it is at 50psi now and its killing me on gas bad. Motor is stock with intake/header on LS ecu obd1.

thanks!

 

Should be more around 40-42 psi

The stock pump is only a 90, why did you buy such a big pump?

 

nah it came with the car man so im jus workin with what i have.

 

hey that 40-42 psi, is that for a stock B18 with a stock fuel pump?

should it be lower since this car has the Walbro fuel pump?

thanks.
