Thread: Fuel Problem

Tweet

I have a 350 Chevrolet engine in a 1960 Biscayne.

It has a 600cfm Edelbrock carb with an electric choke and a mechanical fuel pump.

Recently, the car would not start, so I replaced the mechanical fuel pump as I could see via the clear fuel filter that the carb was not receiving fuel.

After replacing the fuel pump I started the car - it was popping. missing, hissing and back firing.

After a few "let it rest and try again's" I restarted the car -- it idled and ran beautifully - I did notice the fuel filter was full of fuel and drawing hard.....

Then, while running beautifully, all of a sudden the car began to pop. miss and back fire again. I immediately looked at the fuel filter and found that the filter showed very little fuel -- it was obvious the engine was lfuel deprived...

The new fuel pump is an 80gph unit, is it possible the new fuel pump is bad?

Or should I look for something else?

Thanks for your advice....

Sounds like the fuel pump is not delivery the corect amount of fuel to the carb. Is your fuel line crimped at any point? Do you have a inline fuel filter? That could be plugged.

If your car had been sitting for a long time prior to getting it running,you may be sucking up deposits from the tank and lines.I had my tank boiled out at a radiator shop,then I plugged the end coming from the tank and from the line up front sprayed it full of aerosol Berryman Chem-tool carb cleaner,plugged it up and let it sit 48 hours.Then putting that end into a coffee can and went back to the rear and blew it with the air compressor,you won't believe the crap that came out of the lines.Replacing the lines may be a better option also.Before I did that the inline filter plugged up and it quit running too.
