It shouldn't be up and down, that constantly.

You now have to figure out the issue with getting the proper flow of gas to your carb in this situation now.

1. Is it the fuel pump?
2. Is it a fuel line?

Or.

3. Is it the sending unit, inside the tank 😎💪
How hard is it to run new lines? I’m pretty good at messing with cars and changing things out. This is just my 1st carburetor car. I’ve read the fuel sending unit just measure the amount of fuel in the fuel tank and communicate the fuel level to the fuel gauge on the vehicle dashboard. So just leaves fuel line or pump?

It's not hard, but it helps if you have a lift or proper jacks however that is.

The sending unit, does do that but it also has the metal tubes up top, which run to your fuel lines.

If those are clogged, you will have an issue but check the other 2, and if that doesn't work? Then you will have to see if you need another one!

I would start with the rubber fuel lines, a pin hole can cause the problems you are having. There is one from the tank to the steel line running up the frame and one from the line running up the frame to the fuel pump.


The fuel tank sending unit has a screen on it. Before dropping the tank look for debris in the tank white oxidized crud or rust.

If those fail to do it change the fuel pump.

Right now I’m ordering strainer will be here tomorrow. I’m also get mechanical fuel pump. When I disconnected fuel lines from pump I seen black debris come out so maybe it’s clogged?

Today I replaced the fuel pump, hoses to fuel pump and hoses to fuel sender. I will try it today or tomorrow morning. I went around the block and it felt as if it ran way better. I’ll let you know tomorrow how it goes once it warms up

So I went for a ride last night. Maybe 40 minutes. It was running waaaay better. Better acceleration less hesitation. Stopped at McDonald’s and while sitting maybe 5 min. Car just turned off. Started right back up with turned the key. Why do you think it would stall out?
