Available in return and returnless versions, you can rest assured Holley has the solution you need for your EFI fuel pump woes. Now you can convert your factory tank or fuel cell to an in-tank EFI fuel system quickly and easily! And- add the benefits of a Holley Hydramat in the process!

Supports up to 875 EFI or 1100 Carb HP (@ 60 PSI at 13.5 Volts / 16.9 AMP Draw) Of course there are many variables, estimates are based on gasoline. Individual systems will vary based on fuel system design, regulator type, fuel cell location, etc...
