best suggestions for a fp gauge with a sender and adapter. This is important to me. The last one i had was in the engine bay and i could only monitor it at idle and racing the engine. My fuel pump was slowly failing. Kept me from utilizing all my engines potential. I want to know what u guys are using.

buy the gauge, it should come with everything needed. If not its going to use some type of T fitting, with the straight through part a nipple on both ends for the line, and the perpendicular piece to the sending unit... look at summits site.

I have 0-100 psi NON full sweep. Its useless IMO. Not detailed enough.

since A/F is a byproduct of of fuel pressure combined with your tune, i prefer to monitor A/F...

what kind of fuel pump do you have? and also what type of fuel pump failed on you?

This is a very good point, I have a wideband.

I think I am going to pull out the fuel pressure gauge when I redo my interior.

Save your money and buy a wideband.

Are you using a rising rate FPR or something? why do you need to monitor it so closely?

I honestly have never looked at mine while driving. I setup the FP by the gauge in the engine bay and call it good.

I am not trying to rain on your parade, but I have not ever needed it and this is the second car I have had it in. Seems like using that money to put twoard a widedband is a much better choice.
