Are you sure your fuel line keeps pulling fuel form the tank? I don't know what you have for a tank, or tank fuel setup. Inside tank sock filter pluged?
I would run all hard line, and only enough hose to hook connections. As long as the fuel line does not touch the block or exhaust it should not get vapor block.
With the conduit over the fuel once it does gets warm, it won't cool down either! I'd remove it.

The tank is a poly tank. The pickup has no sock on it. It is a stainless steel tube that is part of the sending unit. It is cut at an an angle and is off the bottom of the tank about 1 to 1/12 inches. Also, someone told me that I need a pressure regulator. I thought that was only needed on fuel injection. I believe the pump only puts out 7 pounds of pressure.

Tomorrow I will try to move the metal line a few inches from the intake manifold and valve cover. It that doesn't work, I will try to eliminate the rubber hose from the tank to the pump or at the very least reduce the length of hose as much as possible. I didn't think the hose would colapse unless the pickup tube was blocked or clogged. Thank you guys for the suggestions.

Fuel problem solved!!! The problem was two fold. The fuel tank vent line was crimped and the fuel filter inlet between the tank and electric fuel pump was partially clogged. It is one of those glass filters that can be opened and the filter cartiridge can be cleaned or replaced. I had been opening the filter to clean it but I was'nt removing the inlet section of the filter and couldn't see that it was clogged. I guess this is an example of over looking the simple things. The good news, is that the problem encourged me to to relocate the electric fuel pump to a better position in relation to the tank and short the hoses. All is good once again. Thanks for the help.

Now, install a regulator to bring the pressure at the carb inlet down to 5 psi and you'll be golden. More pressure will not make more hp, it'll only over-ride the needle and seat, blow raw fuel into the intake and give you tuning headaches. Ask me how I know.
