I have a Holley mechanical on mine. a few years ago I had starvation problems. I put in a fuel pressure gauge, the pressure was dropping at high rpm. I put in the new pump and the starvation went away. I since thought I was running lean at high rpm so I installed an air/fuel ratio meter, it's actually on the rich side right up to 7000 rpm. I also installed a AN 6 braided steel line from the pump to the carb but have to original fuel line from the tank. My carb has only one inlet. Bob, maybe you need larger jets on the secondaries if you're running a bit lean. I changed mine out four times to lean it out as I was too rich after the rebuild. I got it close and stopped, I thought with 10.5:1 compression a little rich wouldn't hurt. Ordy, Aeroquip makes hose for socketless slip on fittings for fuel and oil, I think it's fairly inexpensive. If I ever change out my lines I would use that or another brand of slip on fittings and hose for the line from the pickup to the carb and the steel braided for the pressure side from the pump to the carb.
