Gen V LT4 HPFP Wiring Pigtail Adapter Harness - LT1 LT5 L83 L86 L87 L8T DI


We have run out of stock for this item.

This jumper allows the use of the older LT4 HPFP (12711668) with a Bosch connector, on newer GM vehicles that require a Molex connector. This is a common pigtail needed when converting to an LT4 high pressure fuel pump in a later model year vehicle. Simple plug and play!
