Default Fuel Pressure Gauge

Time and time again i see people saying that you need to scan for KR and check fuel pressure before doing pulley swaps to avoid detonation. So i have the Aeroforce gauge to check for KR but need something to monitor my fuel pressure. Has anyone installed a fuel pressure gauge under the hood? I've searched on here and haven't found much. I did some looking over at Jegs and similar sites and it looks like you can get a gauge for a pretty decent price and a fitting that allows you to mount it right on your fuel line. I don't really want to mount the gauge in car and deal with pressure isolators and things like that. Where is our fuel pressure on the 00+ SSEi'* supposed to be anyways?

My adjustable fuel pressure regulator came with one. You can buy it from INTENSE.

Casper'* makes the kit, and sells just the gauge alone:

I bought the same FPR and gauge but found that after a year the gauge which only has a brass bourdon tube was corroding and the gauge was starting to corrode.
I replaced the gauge with a stainless steel unit.

Caspers recommended setting it at 56 - 58 psi......with the vacuum line disconnected. Stock pressure was 52 psi.
When you connect the vacuum line, the pressure will drop 6-8 psi.
