Why a Racetronix F-LT1 Fuel System?
The LT1 F-body cars have a pump that is inside a plastic fill-bucket. The fill-bucket's inlet and check-valve system in combination with the fuel pump are designed to draw fuel from the bottom of the tank via suction. This keeps the bucket full at all times and the pump fully immersed in fuel regardless of the tank level so that when the tank is low on gas and you are doing some hard cornering or acceleration the pump does not run dry and start aerating (air bubbles) the fuel. This happens as the fuel sloshes from side to side in the tank leaving the center low on fuel. The F-LT1 cars have minimal to no baffling in them. This can cause detonation and possible engine damage. The bucket also allows the car to operate with lower fuel levels in the tank due to its scavenging effect. The bucket can also effect motor cranking time as the priming time is reduced under certain conditions. The return line from the fuel pressure regulator is diverted back into the bucket via a filter sock inside so that the unused fuel also helps keep the bucket full at all times. Keeping the pump constantly immersed in gas within the bucket can extend the pump's life by not allowing it to be exposed to open air. Open air within the tank contains moisture and in time will cause the pump to rust / seize up especially if left to sit for long periods of time without the tank topped-up (i.e. winter storage). The Racetronix pump assembly is modified so that it will seal in the bucketís rubber check-valve so that its function is retained. 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 todayís gas and it will not crack, split, swell and collapse like a rubber hose. The standard Walbro kit comes with a short length of 50PSIA rated rubber hose. The Racetronix fuel module is equipped with a one-piece soldered wiring harness made from mil spec. 14 gauge Teflon/silver wire. (upgraded from the factory's 16 gauge unsoldered harness) 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 F-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.
Walbro Fuel Pumps 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 pressures while providing high volumes as well. This is done by squeezing the fuel out between two gears instead of pushing it like most factory vane pumps do. (i.e. factory C4 pump). This positive displacement design makes high-performance Walbro pumps small, light weight, quiet, efficient and reliable. The Racetronix F-LT1 fuel pump assembly uses a 255L/Hr @ 43.5PSI @ 13.5V (300KPa) rated fuel pump.
The Wiring Harness
All fuel pumps are voltage sensitive, the lower the voltage the lower the fuel volume. Gerotor pumps exhibit a significant increase in fuel volume with increased supply voltage. A Walbro pump's average fuel volume increases over 18% by increasing the supply voltage from 12 to 13.5 volts. The factory harness is marginal at best for supplying a factory pump with enough voltage to perform well. This is why the 'hot wire' modification is so popular. Replacing the factory pump with a high-performance pump such as the Walbro GSS340M can easily double the current demand under W.O.T. pressures. The voltage drop in the factory harness increases proportionally to the current demands of the pump. Racetronix has documented tests where the voltage drop in a factory harness has caused over a 25% drop in fuel pump volume. The Racetronix harness uses heavy 10 gauge copper wire to reduce voltage-drop to very low levels. The factory gauge of wire used is three gauges thinner. Our power feed comes off the back of the alternator where voltage is highest. It then runs through a Delphi weatherproof fuse holder and then to the back of the car. The Racetronix harness uses three-position male and female Delphi Weatherpack connectors which plug in-line with the factory harness at the back of the tank. No cutting or splicing is required. A Siemens weatherproof 40 amp rated mil-spec. relay is used. These relays have silver plated contacts and are the best money can buy so that you can be guaranteed to have trouble-free operation. 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. All the harness connections are crimped using certified Delphi crimpers and are soldered as well. All the harnesses we have seen to date from the competition are not soldered. Racetronix supplies a spare ATC fuse, black vinyl wire ties, silicon grease and mounting hardware with each kit. We are including as a bonus our optional battery to body ground upgrade kit. This kit upgrades the under-rated ground wire running from the battery to chassis. It includes a crimped and soldered piece of high strand count 8 gauge copper wire and brass battery nuts with accessory taps.
