Another possibility is that the float inside the carb is malfunctioning.

 

My first old vehicle. I'm clueless, but slowing learning. What do you think about sticking a pressure guage in fuel line before carb?... Hopefully to find out whether it's before carb or the carb.

 

You could test the pressure. You are looking for somewhere between 6 & 8 psi.

 

I do not have a tester.... I figured cheaper to buy just a gauge lol...

 

A gauge will work. That's all that is used to test fuel pressure.

 

update

replaced metal fuel line with rubber line and inline fuel gauge. Is it normal for a fuel gauge to bounce super fast? (0-4 just back and forth) It's bouncing to around 4 lbs.

I swapped line on pump..... there were correct because it ran out of gas lol.

Before putting back on pump I pump air with the compressor to line and blew back into the tank. Runs a lot better but still hesitating. Fuel up to around 8 lbs still bounces steady.

Problems obviously in the tank.. what do you think? Currently I have about $100 in the tank I hate to drain it

 

It is normal for it to bounce with a diaphragm style pump which is what you have. Each revolution of the cam causes the pump push rod to push on the diaphragm arm which pumps fuel.

0-4psi sounds a bit low, but 8psi is good.

Have you considered tearing down the carb and rebuilding it?

 

Just drove about 5 miles... It's driving fine... BUT idle it's rough and wants to die. When I returned home 3 psi again.

I have never done it before. I suppose I could bring in house and tear apart.

 

If it drives ok and only the idle is crappy, that sounds like a carb issue.

Is it the factory carb, Rochester Quadrajet?

 

You know, I just bought it last month. I have never owned anything carbed. lol, I just need to do some reasearch once it's out. I have no idea what kind of carb it is. It's black as **** from gunk
