Carb or EFI Applications Supports up to 900 EFI or 1050 Carb HP Compatible with Pump Gas*, Race gas, Diesel or E85

OVERVIEW

Holley's HP™ In-Line Billet Fuel Pumps are designed to be the perfect companion to your carbureted or fuel injected race car, off-road truck, or any engine needing fuel! The HP™ fuel pumps feature OEM gerotor technology which yields lightweight, quiet operation and 100,000+ mile durability in a cost-effective, attractive package. HP™ fuel pumps are Race gas, E-85, and diesel compatible and can be used in racing applications with 18.5 volt charging systems up to 80 psi.

Features:

  • Billet aluminum construction for durability & good looks
  • -8 an o-ring inlet/outlet for high flow and superior sealing
  • Excellent for use with carbureted or EFI applications
  • Fully submersible in-tank for custom applications, space savings and less plumbing
  • Compatible with 12v to 18.5v systems for street or race use
  • Compact (7.5” long x 3” wide x 2.75” tall) for easy installation on frame rails or other tight areas
  • Proven durability beyond 3,000 hours in gasoline or diesel fuels
  • Weighs only 3.1 lbs.
  • Current draw at 43 psi and 13.5 vdc is 8.6 amps
  • Not designed for use on aircraft of any type.

*Pump gas compatible for intermittent or under 90 degree ambient temperature use

Pump gas use recommendations:

• This pump is compatible with pump gas, but is not recommended for street driven vehicles where the ambient temperature is regularly above 90 degrees

• For street driven vehicles in high temps with pump gas, Holley recommends part numbers 12-600 or 12-1800 for optimum hot fuel handling

• Proper fuel system engineering is critical for maximum performance.

Please see Holley Fuel System Chart in the images above for information about proper installation of your fuel system.

• To reduce fuel temperatures and vapor lock issues, it is recommended to operate these pumps using one pump for daily driving and low power levels and bring the second pump in with a pressure switch or other device when fuel flow needs increase. This will reduce heating of the fuel load by eliminating excess fuel circulating to the front of the vehicle, thru the fuel rails and back the tank.

Will work with E-85 and Diesel!

NOT FOR USE WITH METHANOL!

These pumps do not have an internal bypass. A bypass style regulator and return line are required.

This pump is not designed to use a standard conical seat style (flare) union in the inlet or outlet of the pump. Must use ORB style fitting.
