After I have been driving for about 5 miles the car will start to surge and wants to die. If I slow down to an idle for a minute it will be okay for a little bit and then start again.
Is this due to dirt in the fuel pump or maybe dirt in the carburetor. I have removed and cleaned out the fuel pump bowl and the screen and it seems to have helped a little.
Comments requested and wecomed.
Thanks,
Jim V.

Check the gas tank cap. It must be a vented type and also check to see if the vent is stopped up.

The gas cap is vented and not plugged up.   Jim V.

you may also have to remove the gas tank and have it boiled out at the local radiator repair shop. mike

Has anyone placed an in-line filter in the line back near the tank? If you have a gage to measure pressure it would be interesting to see how much pressure the fuel pump is producing. You may have something plugging up the pick-up tube in the tank. If so, that would require removing and cleaning the tank. I'm convinced your problem is fuel related.

There is no in-line filter. I will try to measure the pump pressure this weekend. Is there a sock on the pickup tube or is it okay to blow air from the gas line into the tank. I have had the tank off and cleaned the tank.
I am also convinced that the problem is fuel related and am about to the point of removing the fuel pump and rebuilding it as well as the carburetor, but I really didn't want to have to go through that.

Sure, you can blow backwards into the tank with air. Remove gas cap, have car outside, use low pressure and listen for noise in the tank. Be very careful as you could rupture the tank, or blow fuel all over the place.

ray: had a terrific amount of sludge in our 29 tank that hadn't been run since 70's. engine starved for fuel. disconnected the inlet line to fuel pump, blew back into tank, reconnected, engine raun fine for couple minutes then starved again. sludge re-accumulated at pickup. cure was removeal of tank and thorough cleanout. no problems since. mike

I didn't get it to register anything on the compression tester, but when I hold my thumb on the outlet and then release it after I have cranked it, it does have some pressure. If I let it pump freely it will put good spurts of gas but not a steady stream. I did find out today that if I travel at about a steady 23 miles per hour, it will keep running and not stop. If I go any faster, it runs out of gas. Bottom line, I think I will have to rebuild the pump.

Today (Saturday), I removed the air dome on the fuel pump and emptied all of the gas out of it and then reinstalled it. I drove around 50 miles today and had no problems with stalling, etc.. Now the real question is why did the air dome fill up with gas, leak in diaphragm or what?
