Racetronix introduces its new E85-compatible in-tank wiring harnesses for use with new high-performance pumps and G.M. / Delphi fuel modules

FEATURES:

  • Plug & Play with factory bulkhead and pump connectors
  • E85-compatible connectors and Teflon wire
  • Upgraded terminals and wiring for best performance

ITWH-029 - Delphi modules up to 2003

ITWH-028 for Delphi modules 2004 and up

Most Delphi fuel modules 2003 and older use their MP150-type bulkhead connector shown below. These connectors are prone to failure hence Delphi's change to their newer MP280-type connectors. The MP280-type connectors provide double the power handling capability when used in combination with one of our fuel pump upgrade harnesses.

NOTES:

  1. If the fuel module has been serviced/replaced, the connector type may have already been spliced/changed to the MP280-type. If so, the RCS-028 bulkhead connector would not be required since the new fuel module would come with it. The MP150-type input connector on the FPWH-017 will not be compatible with the new connector splice so our FPAH-001 would have to be used to adapt the input connector.
  2. Purchase of the bulkhead connector is typically not required because it is native to factory module.
  3. Not all pumps listed are compatible with the factory venturi/jet pump systems built into the factory modules. Racetronix does not provide technical support for DIY modification of the factory modules.
  4. Tall SUV modules may require the 12" ITWH-024. Contact Racetronix with your VIN# for confirmation.
  5. Non-E85 versions of AEM, Stealth 340 and other brands of pumps use the standard Walbro-style connector (RCS-001). New E85 versions of these pumps have power leads and an in-line / external Delphi MP280-series connector the same as the Walbro F90000267 and F90000274 pumps. Check your pump's connector to make sure you have chosen the correct in-tank harness (ITWH) for your application.
  6. If your vehicle has had the factory fuel module changed/serviced, the new replacement fuel modules have the Delphi MP280 RCS-028 connector on top. The factory harness would be cut/spliced with the mating connector for the RCS-028. If this has been done you will require our FPAH-001 harness to adapt it back to the Delphi MP150 connector so that it may plug into the input connector on our new FPWH-017 harness.
  7. C5 Corvettes manufactured 2003 1/2 and later with VIN # 114931 (last six digits) and up as well as all C6 Covettes through 2013 excluding the ZR1. The F90000274 E85 pump is recommeneded over the F90000267 because of its higher pressure handling capability. Use of these pumps will disable module's jet pump which requires other considerations. Corvettes with the Z06 TU476 module will not benefit from a 340LPH aftermarket pump upgrade.
  8. ITWH-033 is for aftermarket pumps equipped with the standard Walbro GSS-style connectors.
