electric fuel pumps

hmm.. most carbs only need 4.5-6psi anyhow. I could see a possible fuel starvation issue especially while drag racing.
It does mention that model runs 4.5-8 psi.. There could be another problem limiting the fuel pressure.

My old tank and fuel lines were clogged and beat to hell. I would run between 2psi and 6 1/2 psi randomly. I have since rebuilt the entire fuel system and now it's a solid 6 1/2 all the time.
