A GM to Walbro direct wiring harness is provided to totally replace the most often burnt and / or corroded factory wiring . Brand X systems require the use of an in-line wiring adapter. (slight module alteration required) |
Voltage differential increases to over 2 volts with increase in line pressure / pump current draw @ W.O.T. This equates to as much as a 20-25% increase in pump volume based on Walbro specs and Racetronix tests. |
|
Weatherproof fuse holder simply mounts with supplied stainless hardware.  |
Redundant ground leads improve pump supply voltage and reliability beyond factory wiring. |

The Pump Assembly Racetronix uses Walbro Fuel Pumps which have set the industry standard in high-performance. Walbro pumps are QS9000 certified and are used as OE equipment in many production performance vehicles such as the C5 Corvette. Walbro's gerotor design is able to maintain high pressure while providing high volume as well. This positive displacement design makes high-performance Walbro pumps small, light weight, quiet, efficient and reliable. 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. The standard Walbro kit comes with a short length of rated rubber hose. The Racetronix fuel module is equipped with a one-piece wiring harness made from Teflon/silver wire. This is the same type of wire used at the factory as Teflon is the most resistant to deterioration when exposed to gas. This harness has a Walbro connector at one end and GM pins at the other which fit directly inside the factory connector. Due to the age of the B-LT1 cars much of the in-tank connectors are black / corroded due to age. The Racetronix harness replaces all these questionable components. The standard Walbro kit comes 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. RACETRONIX WIRING HARNESS High performance fuel pumps need a good power source in order to perform to their full potential. On average a Walbro high-performance fuel pump requires twice as much power as a factory fuel pump. Factory wiring is just enough for a factory pump’s 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 alternator’s 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 Walbro 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. The main length of wire in the Racetronix harness is ten-gauge stranded copper. This 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 40 amp silver-contact 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. A battery to body ground upgrade kit is included. This kit upgrades the under-rated factory ground wire running from the battery to chassis. It includes a crimped and soldered piece of flexible 8 gauge copper wire and battery nuts with accessory taps. We highly recommend this inexpensive option because this is a weak point in these cars. 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. As with most Racetronix harnesses the FLT1-FPWH 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 ATC fuse, 25 black nylon wire ties, silicon grease and stainless mounting hardware with each kit. |
