I'm doing a fuel pressure check tomorrow,

So your fuel pressure was between 56 to 63 lbs? And did you do a fuel pressure bleed down test?

How do you do a fuel pressure bleed down test?


Have your fuel pressure gauge hook up to the Schrader valve, cycle the key on, off to build up pressure on the gauge (highest) and turn the key off, watch the gauge, should not drop off more than 5 lbs. in 3 minutes.

Okay thank you, I'll let you know how it gos and see what your thoughts are. Thank you

It was really warm today and it fired right up so idk forsure what the problem was. But now I can't get my fuel filter off the Nuts are super rusted. How should I get it off?


Spray some good penetrating oil on it and let it set overnight, line wrenches work best on the nut part, regular wrench on the fuel filter. If you cannot get them loose, I've seen in our parts stores they have replacement length lines to patch in using a compression fitting, you would need a clean cut to do this by using a small cutting tool.


Try spray in carb ( just) twice.carb throws a car into shock keep inside if possible. High octane gas if possible
