Holley 12-323 255 LPH Pump Module - Returnless

1998-2004 Dodge Truck 255 LPH Pump Module System - Returnless with 220-20 OHM Fuel Sending Unit

Part Number: 12-323

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! Direct Fit in the following Vehicles: 1997-2004 Dodge Dakota (2WD & 4WD) 1998 Dodge B1500/B2500/B3500 (Full Size Vans) 1999-2003 Dodge Ram 1500 Van/Ram 2500 Van/Ram 3500 Van (Full Size Vans) 1998-2003 Dodge Ram 1500/Ram 2500/Ram 3500 (2WD & 4WD Full Size Pickups) 1999-2001 Dodge Ramcharger (2WD & 4WD - Mexico Only) 1998-2003 Dodge Durango (2WD & 4WD)
