I was looking under the hood today on my civic and was thinking of getting a fuel pressure gauge for the fun of it and was looking, and seen that it wouldn't fit at the fuel filter, without a hose or something. My question is, I was looking at the fuel rail where the fuel line connects, and nut looks like it has regulator on it, kind of like the FPR. I was wondering what that was or if I could get a gauge and a nut kit they sell on ebay and put it there, since it will not fit under the hood with the fuel filter. My other question is timing related. I put the car in diagnostic mode, which is all I thought you needed to do, then use the timing light. Well I did put the jumper in and tried checking the timing, but it was showing way out , and would still advance when revved up.. The car is a 95 Civic Ex, with just an intake and cat back exhaust.
