No Gas to the Carb When Engine Warms Up

Nope, the only thing that counts is the end of the pick-up/screen to the pump inlet fitting, that needs to be sealed end to end. Anything else is just a leak.
Take the hoses off the line at the pump & the tank & blow through it, should be clear, and any pinholes probably will show some wetness from residual fuel with that
kind of pressure going through there. If You have a good Mityvac, You could clear the line & cap one end & hook-up with a hose & see if it holds vacuum......

I think I will replace the sending unit with a better unit. When I looked at it, it looked cheap. It was in the car when I bought it. I read other threads where people were having similar problems and replaced the pick up with a better unit. I have only had this car for about 6 month and really have not been able to enjoy it. I'll blow out the lines and try the vac test. Thanks.
