Fuel Pressure

[massacre]

Hello,

I need to get a fuel pressure gauge to check my fuel pressure. Which gauge will fit my ‘94 4.0L OHV?

Did a search but only found stories of the auto zone tester not fitting?

Thanks I think I am having a fuel issue

You need an adapter down to the same size as a tire valve stem.

Hooked up pressure tester, pressure at idle 30psi. Removed vac line pressure went up to 40psi. Reattached vac line, pressure back down to 30psi.
I am waiting 5 min to see if pressure holds.

Pressure held, seems ok

Where did you go to get the correct fitting? I tried oreillys "universal" kit ($133 btw to rent it!!) and it didn't have the correct size. The guy behind the counter was baffled they didn't have the fitting ANYWHERE in the store.

It came with the gauge I bought.

you can pull the valve core out of the Schrader valve put 3/8 inch hose over Schrader clamp it on

ps I just use a regular 0-50 pound guage

That's the same gauge I have. I do use one of the adapters it came with. Also on my '94 there is a bundle of wires that you have to get around when attaching the gauge. It's almost made me think about making an extension from the rail a few inches out.

That looks just like the one I have
