frustrated, fuel system problem

HELP! Before this car drives me insane. I have a '74 SBthat has been having what appear to be fuel delivery problems. When the engine gets fuel, it runs fine. Occasionally the fuel delivery just seems to piddle out. After the car sits (usually, overnight) it starts up and runs fine (for some random period of time) till stalling out reoccurs. I finally broke down and put an electric fuel pump along with a new fuel filter. Problem RE-OCCURED! After towing the car home, I disconnected the fuel line from the carb and turned on the electric pump to see if I was getting a nice strong / steady stream of fuel, it was not a good steady stream and it seems like it can't pull the fuel. I tried opening the gas cap to see if there was a vacume being created. No change!

Is there another fuel filter somewhere? Could I have a problem with the fuel line from the tank to the pump? Could the prob be the tank itself?

Suggestions please.

if you are going to do it, replace the outlet/nut/gasket too...its cheap....if it has never been removed chances are good you can damage it removing it:

There's a filter screen INSIDE the tank, at the outlet.

If you look inside of the tank, you may find the sock gone. Maybe you will see floating, a piece of foil from an additive bottle that might get sucked to the outlet causing your fuel delivery problem. Make sure your fuel tank can get air and isn't under a vacuum when you have run the car for awhile. Test by removing the gas cap when experiencing this problem.

Late Super Beetles did *not* have the mesh "sock" filter in the tank outlet fitting. Some of them did have an inline filter underneath the tank just before the hose goes into the tunnel.

A good test is to pull the hose off under the tank and watch the flow. Do this when the tank isn't full and have a can ready. Do it *outside*, not in the garage!

If it appears to be blocked in the tank outlet, there may be a big clump of "gunk" (technical term) sloshing about in the tank.

Short term, you can apply compressed air to the line at the back of the car and blow it out (disconnect elec fuel pump).

It's tough to do on a '74 Super, but you can remove the fuel gauge sender to look inside the tank and (maybe) suction out any glob.
