you can buy the summit plumbing kit for @ 200 bucks, it's only -6 line but it will work, it comes with all the lines AN fittings, pump and reg. i've been high 10s with this setup on spray ( altho i know i'm stretching it )

There are a few things wrong with using a EFI pump and lines with a carb. The pump and lines are designed to handle up to a certain HP with high pressure. When you use a 7 psi regulator, you return or restrict every thing above 7, so reduce the level of HP it will suppport. For doing a carb on anything over 300 HP, start fresh with larger lines and a pump that is designed for low press high output.

i tried to use my stock 190lph on my carb car...it blew the seal of the regulator and overflowed the carburator, my advice? buy the holley blue fuel pump kit, it includes the regulator, my pump is installed where the fuel filter was and i installed a plastic filter just before the regulator without a return line...works like a charm
