    Fuel Pressure Gauge Recommendations

    I have been looking on a lot of forums.

    It seems a lot of people prefer a mechanical gauge over electronic.

    My personal preference is electronic.

    What is everybody running?

    Mine are electronic.

    Mechanical are definitely more accurate in some cases and "should" never let you down unless something is wrong with the gauge or something down the line.

    As with anything though things can and will go wrong at some point.

    I have ran both and prefer electric as well.

    I just keep an eye and ear on how my truck is performing and sounding so if I ever get a faulty sensor i can hopefully catch it.

    Definitely a hard decision and lots of opinions on both.

    I have an analog meter.

    The numbers flipping up and down were driving me nuts.

    My FASS has a slight pulse, which makes sense.

    It never stayed in one place long enough to get an accurate reading.

    I would wonder if a digital that is steady is accurate.

    I just used a cheap POS electric analog meter from Amazon.

    It's very accurate when double checking the accuracy.

    That's my opinion.

    Re: Fuel pressure gauge recommendation’s

    I’m running electronic.

    I agree with @Polaraco on the numbers flipping up and down.

    It’s a bit annoying.

    Reviving old thread here, sorry.

    I have my MM3 showing rail pressure, but I want to see my pressure to my CP3.

    Anyone have a write up on how to run a gauge to see CP3 input pressure?

    I want to make sure my in tank lift pump isn't failing.

    You'd just need to install an inline fuel pressure gauge.
