Is there an underhood FP gauge that can just thread onto the test port(like where you tap for a wet nitrous kit), or do you have to tap it in somewhere else? thanks guys.

well summit has this adapter to mount a fuel presure gauge with 1/8" NPT ports. Basically, you cut the fuel hose coming off of the fuel rail test port(For SFMU people), and this just tees into that line. I dont think you can find a gauge that has 4 AN fittings on it to just screw into the fuel rail test port. The easiest way to do it will be to get a 4an to hose barb fitting, then use a piece of fuel hose to connect to the gauge, OR you can try to find a 4AN to 1/8" NPT fitting to fit directly on the gauge, so that the gauge will be right on the fuel rail test port. Here is the piece from summit i was talking about: Summit part# SUM-G1710 6 bucks for that. I dont think thats what you want though...
