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 did the flow test. There was so much gas coming from the fuel tank in 10 sec I had to stop. I ran the engine at idle fo 25 min. same thing, fuel in the filter them empty. I by passed the tank and ran the fuel pump from a gallon of gas. Same thing. So there is a problem with the hard line to the carb or the float level. I never noticed until today, there is a kink in the hard line to the carb. I'm going to take Dan's advice and get ridkinked line.jpg filter.jpg of the hard line and replace it with fuel injection hose and a metal filter. The picture of the filter is when I started the test. The filter is 3/4 full, then empty after 25 min. Thanks
