Fuel Pump Wiring Kit MP150-GT280

This kit has all the parts required to upgrade the factory wiring on GM factory vehicles equipped with the older-style 4-position 150-series fuel module connector to the new-style GT-series connector system. The older-style 150-series connectors are known to fail over time so GM/Delphi has switched all new-production modules to incorporate the GT-series connector system which has twice the current capacity. This fuel pump wiring kit is a must when upgrading to new high-performance pumps which draw 2-3 times more power than a factory pump.

This fuel pump wiring kit contains the following items:

• Racetronix Fuel Pump Upgrade Harness FPWH-017 - Provides a heavy-duty power source for high-performance pumps (up to 30 amps). This harness adapts the older 150-series connector to the new 280-series connector without the need for external adapters or splicing.
• Fuel Module Electrical Bulkhead Connector Kit RCS-028 - Direct-fit 28-Amp rated connector replaces factory 14-amp unit.
• In-tank 12" Teflon wiring harness ITWH-024 - Direct hookup to the fuel pump's connector, NO SPLICING. Compatible with Walbro, DeatschWerks and other aftermarket fuel pumps. Extra long for tall modules used in some G.M. trucks / SUVs.(Positive terminal on left when pump's outlet is held at 12 o'clock. If you are using an Aeromotive pump you will have to reverese the terminals in the pump connector.)

If the vehicle has had the factory module replaced then most likely the vehicle harness has had its 150-series connector replaced/spliced with a 280-series pigtail. This splice is included with most new modules. Our FPAH-004 is required to make the chassis connector backwards compatible with the 150-series input connector on our FPWH-017 upgrade harness.
