Testing fuel pressure, how do I?
What tool do I need also is there an affordable/rentable tool that would let me real fuel pressure inside the cabin. I actually have a fuel pressure gauge on the pillar it has power but isn't hooked up. Anyone know how I'd go about hooking that up? (previous owner didn't leave me any instructions; its a autometer brand)

It's somewhat random about every 3rd start-up after 5-10 minutes of driving it will start getting really rough. Acceleration is a little better but I think its lacking. The plugs only have 20k or less miles on them same with the wires. The fuel system though is "custom" and has always been somewhat quarky.
I also took a look at the wires and they look clean and unscathed.

Maybe my car doesn't run on fuel but some sort of mythical beasts blood and its just low on beasts blood. I'll try slaughtering a lamb in my corvettes honor and see if that helps the situation any.

are you wanting to test fuel pressure ? if so you need a fuel pressure tester and it hooks uo to the end of the fuel rail on the drivers side , take the cap offf the schrader valve and screw on tester and then start the car , if you want the gauge hooked up , without seeing what is there and what has been done . have no idea , but somewhere it has to hook into the fuel system somewhere

I would go with either how test or how to hook up the gauge either would tell me fuel pressure. The gauge only has power its just a matter of I'm not sure on a corvette how/where the sensor would hook. I checked autometers site but they only have tutorials for an oil pressure and A/F gauge.
I pulled the fuel pressure gauge out its non-electric. It has the regular power then a threaded connector with a small nipple like thing on the end.

Plumbing a fuel line into the interior cabin is not wise.
Sell it and buy an electric gauge. The sending unit that will come with it connects to the fuel rail as described above. You'll need a #4AN to 1/8" NPT adapter.

What electric ones do you guys like? I think I'm going to buy the A/F gauge as well I don't have nitrous yet and probably wont for some time and A/F seems like a darn handy gauge.
