Pics or link? How do the electric ones work?

They have a transducer that attaches to fuel rail and sends signal to in cab gauge. No one should ever run a mechanical fuel pressure gauge in the cab. But I think they were talking about leaks at the fuel rails. They do break down a lot... thank goodness they have a warranty. Im on my third gauge.

Oh, fyi I am running a fuel pressure and boost gauge on my daily driver.

I installed the fuel pressure gauge, it reads about 55-58 at idle and once I give it gas it goes up to 60psi

That's perfect. When you put the turbo on, the fuel pressure should go up 1 psi for every psi of boost, if you have a return-type system. That's starting from your baseline fuel pressure, which is engine off, key on. Turn the key on and off several times and watch the pressure while the pump primes, the maximum is your base pressure.

if ya'll had to rate most important to least important gauge for a turbo, what would it be? I have a 2 gauge A-pillar (for the wideband and boost gauge) but now I got the fuel pressure gauge- so I bout the TTS gauge pod that goes where the dash pocket is to the right of the ac controls

problem is, with the fuel pressure there it's some what hard to actually read it (it has a bubble lens on it causing it to be a little distorted when you look at it from an angle). If the wideband was there it would probably be the easiest to read - the boost gauge would be the 2nd easiest to read. I'm wondering if I should put the boost gauge or wideband there and move the fuel pressure to the A-pillar

or, am I out of luck and all the gauges are equally important lol

Order of importance to me:

1. Wideband
2. boost
3. fuel pressure

if you have inadequate fuel pressure, you will see a lean condition on the wideband

A cheap way to monitor your fuel pressure is to use one of the f/p sensors from off of aeroforce technology. If you are using a tuning program that allows you to have inputs to log using a 0-5volt setup. These work great. Functions just like your wideband on your input box.
Just a suggestion. Works great for me.

actually, I was going to do that- but since I was running my wideband off the aeroforce I wasn't sure if I could run 2 sensors to it (the fuel pressure being the other added)

but since aeroforce doesn't have a phone number to call, they only have the forum- I posted asking if I could use 2 sensors w/ one aeroforce and after a week or so and not getting a response I just bought a separate fuel pressure gauge...

but using the fuel pressure on the aeroforce to have right there with the wideband would have been the best setup ever... hopefully my fuel pressure gauge will go out soon so I can just order the sensor kit and use the aeroforce
