Why use a Racetronix F-LT1 Fuel Pump Assembly?

THE PUMPS

The FPA-003A incorporates our new RXP Turbine-Tech fuel pump which supplies 255LPH of fuel @ 43.5PSI @ 13.5V*. Racetronix RXP pumps use new turbine technology to reduce pump noise, improve reliability and provide enhanced compatibility with Ethanol enhanced fuels. This pump and harness combination will typically support 600 flywheel horsepower. This HP number may be less with forced induction applications which require richer air/fuel mixtures and higher fuel pressure.

* Our FPWH-003 is required for for a HP pump to meet stated performance specifications because the factory wiring was not designed to handle high-performance pumps which draw more than twice the power of a factory pump. A performance reduction of 15-25% in pump performance can be expected along with reduced reliability when a HP pump is run off of the factory harness.

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 buckets 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 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 14 gauge Teflon wire. (upgraded from the factory's 16 gauge 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.
