Hey all! I'm potentially having fuelling issues and i want to hook up a gauge to make sure my FPR isn't shot. Where's the best place to splice into? Before the FPR, or on the return line?

thanks guys

Mine has been checked in the past by attaching a hose for a gauge before the FPR.

I'll second that. I check mine quite regularly, and I tap in between the fuel rail and the FPR. I bought some high pressure injection hose, and lengthened it to make it all a bit less fiddly.

on my 9000 the FPR is mounted ON the rail though, but i'll give the pre FPR hook-up a go. thanks guys :D

hey all, again :D So, also, i was wondering, is there a way to differentiate whether it's the FPR or fuel pump causing the issue if i do come up with low figures. (i'll be installing the gauge tonight) i'm thinking it might be FPR, as my problems only occur at low idle, and dissipate at boost. Perhaps the boost helps raise the fuel pressure, and until then i'm having issues?

thanks for any input,
