Default Autometer fuel pressure guage, HELP
Well i hooked everything up and turn the key on and start the truck and the guage needle goes all the way over to the right, comes back down to 0 psi and then sweeps back up to 100.


any ideas on what the hell is wrong?

now its working, lol It looks like its not reading accurately though, when i hookup the EFI Fuel pressure guage (maint. type) it reads a little higher, when i compare the two the autometer reads lower at idle and @ WOT. Anyone else have this problem with their guage.

Where do you have it tapped in to? Never compared mine to a manual gauge.
