Hey Stoker,

I'm gonna have a similar engine setup soon and I'm in the process of building her right now. Any particular reason why electric fuel pumps are chosen over mechanical fuel pumps? Also, the fuel lines are 5/16 lines right? What would be the next step up?

Also, what model holley did you use? red? blue?

Sorry I wasn't able to answer your questions.

Regards,

Erik

I stepped up to 3/8" fuel line and a electric pump (Holley Blue) when I was restoring my car. One nice plus is I have a '69 tank that already has the larger outlet on the sending unit too.

As for the pump, 10 years ago it was hard to find a mechanical high volume fuel pump. It was easier to go electric and not worry about fuel supply problems. Also, I was able to run the fuel line on the passenger's side of the car and run a straight shot into the carb, instead of running a line over the top of the engine.

A Holley Red pump and stock 5/16" lines was enough for our old engine to run 12.00's @ 111 mph in the '66.
