Updating your racing fuel system to EFI is so simple! Holley is excited to introduce our Holley Fuel Cell EFI Pump Modules. 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 12" deep. The EFI modules are available with single 255 LPH and 450 LPH fuel pumps. The module kits include all the hardware to install into your existing fuel cell. All that you need to add is your fuel line. ***Assembly fits common RJS, Jaz, Summit, Jegs, RCI, Speedmaster and Speedway fuel cells. ***Supports up to 550 EFI or 700 Carb HP (HP Rating @ 60 PSI at 13.5 Volts / 10.4 AMP Draw)
