Why RFPK-002 Was Retired
RFPK-002 upgraded the chassis side only. Its FPWH-002 hotwire harness took power from the battery through a fused relay and delivered it to the factory bulkhead connector on the hanger. From the bulkhead down, the kit relied on the car's original pass-through terminals and the pump's pre-installed in-tank pigtail.
That was a solid upgrade in its day, but it left two known weak points in place:
- Factory bulkhead and in-tank wiring — the original small-gauge pass-through and in-tank leads still carried the full pump current, so some of the voltage gained on the chassis side was lost again inside the tank.
- Shared sender ground — the stock in-tank layout ties the fuel-level sender return into pump ground. With a higher-current pump, that shared return can skew the fuel gauge reading.
RFPK-028 fixes both. It adds a heavy-duty intermediate harness (IPH-002HD), a new 4-way bulkhead connector assembly (BCA-4W) and a dedicated Teflon-insulated in-tank harness (ITWH-058), carrying full 10 AWG power and ground all the way to the pump with the sender ground kept fully isolated end to end.

Already Own an RFPK-002?
Your installation continues to be supported through the forum. For replacement parts:
- Pump — the FPA-002A pump assembly is still available and drops straight into your existing setup.
- Harness — the FPWH-002 has been discontinued and is not available as a replacement. If your harness needs replacing, the FPWK-028W wiring kit supplies the current FPWH-028 chassis harness together with the IPH-002HD, BCA-4W and ITWH-058, bringing your existing 255 L/hr pump installation up to the full RFPK-028 specification.
Frequently Asked Questions
Can I still buy RFPK-002?
No. It has been discontinued and replaced by RFPK-028, which includes the same pump plus the full HD wiring path.
Is the pump the same?
Yes. Both kits use the Racetronix RXP 255 L/hr FPA-002A assembly, rated 255 L/hr free-flow and a nominal 225 L/hr at the F-body's 58 PSI base pressure.
Does RFPK-028 fit the same cars?
Yes — 1998 LS1 Camaro, Firebird and Trans Am with the metal tank and swing-arm hanger. 1999–2002 cars need a different kit.
My FPWH-002 harness failed. Can I get another one?
No, the FPWH-002 is discontinued. Order the FPWK-028W wiring kit, which replaces it with the current FPWH-028 and adds the HD bulkhead and in-tank components. Your FPA-002A pump is retained.
My pump failed but my wiring is fine. What do I order?
Just the FPA-002A pump assembly. It is the same pump used in RFPK-028 and installs in place of your original.
