Looking to put a fuel pressure gauge inside my car. Anybody help me out? I looked at the autometer website and realized a mech. gauge shouldn't go in for obvious reasons. Has anyone installed a electrical unit? If so was it difficult install? Can anyone explain how and where they put theirs?

 

Here's how I did mine:

Sorry to hijack- but how are the accuracy on those electrical gauges? The mechanical ones I've seen only come in 0-15 and are crap reading under 5psi.

 

From what I've read, they aren't very accurate. I'm planning on finding a mechanical gauge to hook up and compare to the electrical. Then I'll see if I can adjust it. If not, I'll know what it means when it says 8 PSI.

nice! is your fuel pressure mech. or electrical?

 

Electrical.

 

You will need an isolator to run a mechanical pressure gauge inside. Im not a fan of electrical gauges.

I don't plan on installing a mechanical gauge in the car...I just want to put one in the line to see what my fuel pressure really is, then compare it to what the electrical gauge reads.

if thats all you want just go to advance and get a little inline gauge its like 10 - 20 bucks

 

what size is the line going into the carb?
