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.
Features tinned copper for maximum current flow and corrosion resistance. Adhesive lined heat shrink tubing shrinks to form a tight seal and the ultimate in vibration and strain relief.
