Mechanical versus electric fuel pump

[Anthony]

Wayne, from what you have stated, I'd just keep the mechanical. But, if your fuel tank has 2 outlets, like my car, you could run two fuel lines up to the engine, one line to the mechanical, the other to a switch activated, rear mounted electric (keeping this pump mounted as low as possible). Both my lines are -6AN, about 3/8", but -8AN, 1/2" would be better. You could then turn on the electric if drag racing or road racing if your mechanical is not up to snuff, like the way mine is.

If you have only one tank outlet, you could insert a T fitting and do as stated as above, or there are electric fuel pumps that are made to bypass fuel , act as a booster pump when activated, to your mechanical pump, but I'd guess there is some restriction when they are not activated.

I thnk the mechanical in general is more reliable, and choose to run my car this way for street driving or a little spirited driving. But, I need the additional electric for serious engine demands.
