Default 43 psi fuel pressure @ idle ok?

Hi guys,

I'm getting 43 psi @ idle after installing a walbro 190 HP fuel pump with stock FPR. Is anyone else getting this? I heard 35 psi is normal correct?

Thanks,

t.t.

You should have checked the pressure before you installed the 190 so you can compare, pressure will vary from car to car.

what do you get when you pull the vacuum line on the fpr?

I'm idling around 950 rpm. I'm pulling the signal between the metal tube and the stock FPR. Is the signal between the FPR and the rail a better place?

actually I take that back, the FPR is on the rail. so I guess I'm really getting 43 psi at the rail...
