Re: Carburetor or Fuel Pump Issue
I'll try a new neoprene gasket on the fuel pump and check out the gas line to the tank.

Re: Carburetor or Fuel Pump Issue
I've had the opposite experience with fuel pump bowl gaskets. I have found that cork gaskets work better for general use. Neoprene may last longer, but it gets hard after a few years.

Copper is not a good choice for a fuel line due to work hardening causing failure. Gasoline is not what you want to leak under your car. Your original line was copper plated rolled steel, which is still available. A newer product, Cuproweld, beats all competition for ease of use and longevity. This is the first time I've heard a recommendation to use neoprene over cork. Cork will perform well forever, while neoprene ages quickly. Soak your cork in oil for a good seal that never dries out.

Re: Carburetor or Fuel Pump Issue
Fuel pumps, mechanical or electric, only pump liquids. The new gas has methanal witch boils easier than the old gas, as low as 95 degrees. Check the tail pipe, and muffler area to see how close to the gas line they are. New cars with fuel injection return hot fuel to the gas tank to be cooled. Rebuilding the carb and fuel pump WILL NOT SOLVE your problem. By the way Charlie is the best.

Used neoprene gaskets on the fuel filters on farm tractors for years and the gaskets did not get hard - used the same gasket continuously as I have done on my Ford fuel pump since 1988. |

That's make work. Before replacing them, check to see if they are the problem. Easy Peasy.

Re: Carburetor or Fuel Pump Issue
If you go to an electric fuel pump, you have to adjust the fuel pressure with a regulator. I believe 3 lbs of pressure is the recommendation. My pump is a 5-8 lb unit that was cranking 8lbs of pressure into my Model 94. All kinds of issues (flooding, fouled plugs, etc).

Remove it from the carb. The valve will stick to your tongue with suction in one direction.

Re: Carburetor or Fuel Pump Issue
I checked the cork gasket in the sediment bowl. It fell apart. I happened to have a neoprene replacement. We'll see how it goes.

Re: Carburetor or Fuel Pump Issue
I let the car sit for 5 days. The fuel level in the sediment bowl was full. I choked it and she started right up. I'll continue to monitor the situation.

Which sediment bowl? You have 3. It's really the float bowl that you monitor, not the sediment bowl.

Re: Carburetor or Fuel Pump Issue
That tells you nothing about the condition of the carburetor. The float bowl is under the air horn. That is where you watch the fuel level.
