Holley is excited to introduce our Holley Fuel Cell EFI Pump Modules with dual VR Series Brushless Fuel Pumps. These drop in modules come with two controllers and harnesses to give you VR fuel pump power inside your fuel cell. While the name includes EFI, these modules can be used as an upgrade for carbureted systems as well with the proper regulator. The modules were designed to drop in as a direct replacement for your existing 12 bolt flange fuel cell cap assembly. The billet top flange includes an 8AN inlet port, a 10AN outlet port, and a fuel filler cap. The fuel pump depth is fully adjustable from 7.5" to 11" deep. The module kits include all the hardware to install into your existing fuel cell. All that you need to add is your fuel line. Update Your Fuel Cell to EFI The Easy Way!
