Hi folks, after some confusion I thought I'd put my fuel pressure regulator on the correct way up - having looked at the manual a bit more closely it seems to show conflicting info.

and

These do not agree...page 16 shows the end of the sensor connects to the fuel rail, page 5 shows the end of the FPR connected to the fuel tank return. Could somebody please take a quick look under their bonnet and let me know whether the end of the FPR connects to the fuel rail or the fuel tank return??

 

Cheers

Lower outlet goes to the Rail, upper outlet goes to the tank return

Ok, ta, so you're saying page 16 is correct??

 

A couple more odd things, I've just checked the fuel pressure, pulled the fuel pump fuse to relieve the pressure, engine just kept on running, is this normal?? Pressure was around 40 psi at 'idle' (it won't currently idle with any stability), as soon as I turned the ignition off all pressure was lost within about 4 seconds - I'm pretty sure this isn't normal - any suggestions?

 

Cheers

Hmm...confused myself a bit with this one. It seems that it's not possible to fit the FPR upside down with connections reversed...

As Dave says. So so long as the feed at the end come from the fuel rail and the one between the bracket and the other end returns to the tank you could I suppose have it anyway up you like.
