Pump Wiring Kit MP150/280, W450 CK*
FPWK-017WD - Fuel Pump Wiring Kit MP150/GT280 Walbro 450/525 98-03 GM SUV CK
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 30-Amp rated connector replaces factory 14-amp unit.
- In-tank Teflon wiring harness ITWH-029 - Direct hookup to the fuel pump's connector, NO SPLICING. Compatible with Walbro DCSS 450, 525 AM340 and other E85 pumps with the Delphi MetriPack 280-Series connector. This harness is 12" long for use with tall modules. (Tall modules may use our ITWH-038 in-tank harness bundled with our FPWK-017WDX kit.)
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 FPWH-023 harness is required so that the chassis connectoris compatible with the 280-series input connector on our FPWH-023 upgrade harness.
Always check the pump polarity markings on top of the pump. RED +, BLACK -
