1968 360 stalling
I was driving down the highway last morning (47 degrees,dry and engine almost to temp) and all on the sudden my 68 360 acts like it's fuel starved. The engine did not totally die at first, but when pushing on the accelerator had no power, finally coming to a stop. Sitting on the side of the highway, if I pushed the accelerator it would move along very slowly with slight surging until I backed of the pedal. About a 1/4 mile down the road it finally stalled out, at which point I pumped the pedal a few times and it started right up and drove normally for a couple of minutes. This process of pumping fuel to the carb and driving normally for a bit continued all the way home. I'm going to check the fuel filter, spray out the carb, check for leaks (fuel & vac) and check for fuel on both sides of the fuel pump, any other ideas? Thanks!

Your problem could be a bad pump. If you have or can borrow a fuel pressure guage, you should have between four to six psi. To check volume, you need to devise a way to fill a pint container with fuel from the pump, with the engine running. Your pump should fill a pint container in about 30 seconds. Be extremely carefull with an open fuel system and a running engine.

How many fuel filters do you have? The obvious one screws into the carb, but you have at least one and possibly two more. You might have the can type fuel filter atop your fuel pump, and on the pickup tube of the gas tank sender, there is a plastic screen. Age and poor quality gas can clog it up. The sender has to be removed to get at this part. You'll need a new "O" ring gasket, when you re-install the gas tank sender.

Looks like it could be the sender unit filter as everything else looks good. Earl's inline fiter was clean and H/D fuel pump working correctly. Gave the carb a full can of spray cleaner and took it for a test drive without incident so far.

C0AZ-9202-A float, fuel tank sender (if your gauge is off)
C0AF-9276-A "O" Ring, fuel tank sender (gasket)
Note: Ford may have changed the suffixes on some of these numbers.

Check your accelerator pump on the carb, look down into the carb and pump the accelerator and see if you are getting a good shot of fuel.

Fuel flow looked good in the carb. It may have also been that I did not drive it for ten days while we were on vacation. This is a daily driver and was giving me heck for not taking care of her.
