FL98 Fuel Pump Kit (RXP255E)
RFPK-005 - 1985-1992 TPI / L98 Camaro / Firebird / Trans AM
Racetronix Fuel Pump Kit
The RFPK-005 is recommended for factory HP upgrades to 600FWHP @ 43.5PSI using the factory lines and fuel pressure regulator. HP support may vary for N/A or F/I motors. Please factor in a 20-25% safety margin between what your motor needs and what your fuel system can supply. Please contact your local Racetronix dealer to discuss your fuel requirements.
Racetronix Fuel Pump Assembly
All fuel pumps are voltage sensitive, the
lower the voltage the lower the fuel volume. High-performance pumps exhibit a significant
increase in fuel volume with increased supply voltage. A 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 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 weatherpack connectors which plug in-line with the
factory harness at the back of the tank. No cutting or splicing is required. High-quality
weatherproof fuse holders and relays are used for
maximum reliability. 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 supplies a spare fuse, black vinyl
wire ties, silicon grease and mounting hardware with each kit.
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.
