Holley 12-321 450 LPH Fuel Pump Module - Returnless w/ 105-5 OHM Sending Unit

Not Available

Update the fuel system in your Dodge truck with a high performance in-tank EFI fuel pump module. These fuel modules fit inside the factory tank & feature a billet aluminum flange, Hydramat®, fuel sending unit, and high performance pump. Choose from 255 or 450 LPH (liters per hour) fuel flow & return style or returnless design.

The amazing HydraMat® is Holley's patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks as well as racing fuel cells. During hard cornering, acceleration, stopping, inclines, and low fuel conditions fuel runs away from the fuel pick up which introduces air into the system resulting in poor engine performance and even stalling. HydraMat is the solution!
