you have to use an inline gauge, and put it inline between the fuel filter and the fuel rail, it should read 38 or 42 pis at idle (sorry been a while and I'm too lazy to check but thats the neighborhood) and since you asked I'm guessing you have a problem? car to tell us more?

^ Yup. My pressure is a steady 44 psi. You can get a decent cheap gauge from summit racing. This is what I use, it costs a little under 30 bucks for everything but it's very steady and I haven't had any problems with it.

passenger side. Next time, consolidate all your issues into one thread, because a lot of the time, problems can/will be related.
