right now I have a carter and a holley 1-4 regulator.

I am installing a 13bt with a atkins 7in supercharger and a streetavenger 670 holley.

i know I need a new reg but will the pump I have and lines flow enough for this setup?

I had planned on getting a quieter pump anyways but should I get bigger lines?

 

Ask Atkins, they "should" know what their setup will require.

 

good Idea.

 

That seven incher should have that car screaming down the track.

 

The fuel pump's way too small. You need something that will put out the required pressure for that carb (6psi?) plus whatever boost pressure you plan on running and then some.

There's a billet Holley pump that has an adjustable 10-25psi bypass valve. Something like that would work pretty well. Or maybe even an EFI pump.
