Fuel Pressure Tester

The carb for my 72 LT-1 is on its way back from Custom Rebuilt Carbs and I want to check the fuel pressure before I install it. Any recommendation for a reasonably priced fuel pressure test kit? I’ve been looking on Amazon but most of them seem to be made for higher pressure fuel injection pumps.

Thanks.

Any auto parts store will have a vacuum and fuel pressure tester.

Thanks for the suggestions. I was able to cobble together a gauge and an old fuel line and was able to check the pressure. All is good.

I used a unit from Harbor Freight. It worked well. After many tests I was averaging about 6psi while cranking dead headed.

I also had my carb rebuilt by Phil. (72 LT1) You will be happy!
