Help!
Installed the pump and lines early this morning with no problem. Left the fuel line fitting slightly loose at the 45 degree fitting at the carb fuel line with pressure gauge. After cranking for a few seconds got fuel at the 45 degree fitting but no fuel pressure at the gauge and no fuel in the bowls. Tightened the fitting and cranked again for about 10 seconds, but no pressure and no fuel in the bowls? Never remember having to prime the carb or? Coil wire off, just trying to pressurize the fuel system. Need help! What is happening that I'm not getting fuel to the bowls?
Thank you.

I've been battling gremlins myself recently. two steps forward, one step back.
I pressurize the front pump with an electric pump in the trunk. That helps particularly when the car sits for a few weeks without running it.
Apparently there is some method in which the original fuel lines are bent from the pump to the carb.
It seems that metal tubing doesn't like 90 bends even if nice and smooth with a tubing bender method.
The 90 degree bends foster vapor lock, even cold. Strange but apparently true.
In my dual 4 set up I recently eliminated the factory dual 4 fuel log due to space conflicts. I went through extraordinary efforts to bend several configurations of tubing to replace it.
All that did was creat vapor lock under normal operating temperatures. I'm still working this out and may need to go back to the original fuel log? I'm not there yet but the answer from me is avoid 90 degree bends in both the metal fuel lines AND hoses.
Truth is stranger then fiction. I know. I'm strange too?
