Adjusting FPR

[iowaTSIfWd]

Hey just a quick question. When adjusting my FPR i read in places the you need to disconnect the vaccum source. Im not sure how true this is. If someone could clear this up for me that would be appreciated. Thanks!!!\\

Oh i do have the walbro 255 hp.

yes remove the vaccum line then set the fuel pressure then re-attach the vaccum line.

what is the reason for doing that?

the FPR is connected to a FRP solenoid, which controls the fuel pressure. when you have the like disconnected you are seeing BASE fuel pressure. The computer (solenoid) will adjust pressure accordingly.

not exactly why dsm decided to do that. dont see many cars that self adjust the fuel pressure. might have to do with the nice fuel cut program they use and or the BCS. helping to save ur engine.

OK, im in the process of setting up my fuel stuff to...now do you remove the vac. source when the car is running??? Do you plug it or leave it open?? and should it be set at base (43.5psi on 2G)? Thanks!

you just pull it off, while running. i dunno what base is for a 2g but it sounds about right.
