Often plumbing a fuel system becomes one of the most cumbersome experiences due to the mounting of the fuel regulators. This competition designed fuel log solves all of those problems. The Billet fuel log is machined with a 1/2”npt inlet so that it can be threaded in to a high volume 6 valve style of fuel pump. Next dual 3/8”npt outlet ports allow for easy mounting of Holley style fuel regulators while also providing optional fuel return and pressure ports.
Get rid of that old stamped steel bracket and replace it with this
adjustable. highly polished billet bracket. Will not work on systems
with circulating pump! Fits Big Block Chevy engines.
