The Holley 12-768 VR1 Series quick kit pairs a brushless, twin-screw-rotor fuel pump with a harness and a 2-step speed controller, plus a 26-163 bulkhead harness. It is the same kit as the 12-767 with the added bulkhead harness. The pump is rated for 130 PSI and is listed for street/strip carbureted or EFI combinations, supporting up to 2150 EFI HP or 2400 carburetor HP. The controller runs the pump at a low speed for lower fuel demand or at full speed for high demand, and the pump can be submerged in a fuel cell or chassis mounted.

This pump has no internal bypass, so a bypass-style regulator and return line are required. Do not use a standard conical seat style union (for example AT981510ERL) at the inlet or outlet, since it blocks flow and leads to pump failure. Use a contoured port fitting with an O-ring seal, such as AT985010ERL. Methanol and E85 compatibility is for competitive drag racing only, with the system drained and flushed after each event. Horsepower estimates are based on gasoline at 18.5V and will vary with fuel system design. The pump is not for use on aircraft.
FAQ
What is the difference between the 12-768 and 12-767?
Both include the VR1 pump, harness and 2-step controller. The 12-768 adds a 26-163 bulkhead harness.
How much horsepower does it support?
Holley lists up to 2150 HP on EFI or 2400 HP carbureted, based on gasoline estimates at 18.5V.
Does the pump have an internal bypass?
No. A bypass-style regulator and return line are required.
What fittings should be used?
Use contoured port fittings with an O-ring seal, such as AT985010ERL. Conical seat unions block flow and can cause pump failure.
Can it run E85 or methanol?
Yes, for competitive drag race use only, with the system drained and flushed after each event.
