The Pump Assembly

The RXP255 pump uses new turbine technology to reduce pump noise, improve reliability and provide enhanced compatibility with Ethanol enhanced fuels.

It is a known fact the the factory BLT1 sender suffers from corroded and burnt fuel pump wiring. Generic fuel pump kits come in-tank wiring adapters forcing you to use these old corroded and burnt wires. The Racetronix BLT1-FPA comes with a complete new gas-resistant Teflon in-tank wiring harness to replace the factory wiring. Generic kits include a piece of rubber hose to replace the factory fuel tube. Racetronix supplies a factory-type non-kinking fuel tube which is more resistant resistant to the additives in modern pump gas (i.e. Ethanol).

The Racetronix pump assembly is fitted with a factory style fuel tube not a rubber hose. This hose is important as when the fuel module is placed back in the tank it must pivot which can cause the rubber hose to kink. This fuel tube is much more resistant to the solvents in today's gas and it will not crack, split, swell and collapse like a rubber hose. Generic pump kits comes with a short length of rated rubber hose. Racetronix in-house manufacturing facility produces a replacement one-piece in-tank harness. This in-tank harness plugs directly into the pump and into the factory bulkhead connector thereby eliminating all the factory wiring and the need for adapters or splicing. The Racetronix harness is made with Teflon wire. Teflon is the most resistant to gas and solvents. All connections are assembled using our computerized crimp-quality monitoring system and then circuit checked for the utmost in reliability. There are no wires to cut, crimp or splice.

Many of the in-tank connectors are corroded due to age. The Racetronix harness replaces all these questionable components. Generic kits come with a plastic coated in-line wiring adapter. This adapter must plug into the existing questionable factory in-tank wiring thereby adding additional connections and length.

Many of the factory bulkhead connectors are now failing. This is the yellow molded connector which is pressed into the top of your fuel sender. This kit includes our BLT1 bulkhead connector assembly which replaces this connector and wiring with new upgraded components.

Why use a Racetronix Fuel Pump Upgrade Harness?

  • Plug & Play (no cutting or splicing required)
  • Weatherproof factory connectors
  • Heavy automotive-grade copper wire
  • Heavy-duty weatherproof relay
  • Weatherproof fuse holder with stainless hardware
  • Alternator-direct power for maximum voltage
  • Silicon grease, spare fuse, wire ties included
  • Body ground upgrade with battery nuts (optional)

High performance fuel pumps require a good power source in order to perform to their full potential. On average a high-performance fuel pump requires twice as much power as a factory fuel pump. Factory wiring is just enough for a factory pumps power requirements because manufacturers need to save cost and weight. Racetronix field tests have shown that running a high-performance fuel pump off of the factory wiring can cut pump performance by 30% or more. Problems with failing factory relays, connectors/terminals and fuse contacts are also common when excessive load is placed on them.

The Racetronix plug and play harness is designed to remove all fuel pump load from the factory pump circuits while providing the pump with a new heavy-duty power source. The Racetronix harness gets its power directly from the alternator's battery terminal. The voltage at the alternators output is typically 1-2 volts higher than at the battery when the motor is running (high charge/load conditions and WOT). This means that your high-performance pump can provide as much as 20% more fuel in some cases. The Racetronix harness uses high-quality automotive-grade wire which is resistant to oil, gas, heat and rot. This Racetronix harness uses wire that is three to four gauges thicker than factory wire which helps reduce resistive power loss to almost non-existent levels. This helps improve pump performance by as much as another 10-20%. High-quality weatherproof fuse holders and relays are used for maximum reliability. The Racetronix harness has factory-type connectors which plug directly into your fuel pump module/sender so no cutting or splicing is required. The Racetronix harness has a redundant ground upgrade as it is necessary to improve the harness on the negative side of the pump's supply as well.

Racetronix harnesses are considered the best by which all others are judged. Attention to detail in every Racetronix harness is evident at first glance. Racetronix spares no expense to ensure reliability, ease of installation and performance.
All Racetronix harnesses are assembled using our computerized crimp-quality monitoring system and then circuit checked for the utmost in reliability. This Racetronix harness is backed by our limited lifetime warranty.

There is nothing worse than being in the middle of an installation only to find that the manufacturer has skimped on installation hardware. This is why Racetronix supplies a spare ATM fuse, 25 black nylon wire ties, silicon grease and stainless mounting hardware with each kit.


An optional battery to body ground upgrade kit is available. This kit upgrades the under-rated factory ground wire running from the battery to the chassis. It includes an 8 gauge copper wire fitted with terminals and battery nuts with accessory taps. We highly recommend this inexpensive option because this is a weak point in these cars.
