W1 Fuel Pump Assembly
The FPA-007 is recommended
for factory HP upgrades to 600HP @ 58PSI 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. Our FPWH-007
wiring harness is recommended to maximize performance. Please contact
your local Racetronix dealer to discuss your fuel requirements.
What sets the Racetronix
W1 pump assembly apart from others?
A factory-style fuel tube
is clamped to the pump's outlet for added reliability under high operating
pressures. When the fuel module is placed back in the tank it must compressed
causing the tube to bend sharply which can cause standard rubber hose to
kink and fail. The fuel tube is highly resistant to the additives in today's
pump gas which will attack and dry out even the best R9 and R10 rubber
fuel lines. This is why G.M. uses them as OE equipment.
WARNING: Some copy-cat pump kits use a longer generic flex-tube or rubber hose which
can bind up and puncture once the module is compressed back into the tank.
The Racetronix W1 pump assembly
is equipped with an outlet which supplies the factory venturi system which
is required to keep the factory system fully functional! All other pump
solutions to date do not have this feature which requires a hole be punched
in the bottom of the fill-bucket thereby dangerously disabling its functionality.
WARNING: Some copy-cat pump kits use questionable venturi fitting insertion processes
which could lead to internal pump contamination and pre-mature pump failure.
Racetronix insertion process was perfected and proven after two years of
development and field testing prior to production. Racetronix has stress
analysis tests to backup our process.
The Racetronix in-tank pump
wiring harness eliminates the need for a wiring adapter or splicing which
can be unreliable and can cause performance loss. One end the Racetronix
in-tank harness has a Walbro connector that plugs directly into the pump
and the other end has a Delphi connector which plugs directly into the
sender. Teflon wire is used just like in the factory because
it is the most resistant to gasoline and its additives. We upgrade the
gauge of wire used from the factory to reduce voltage loss which maximizes
pump performance. All Racetronix harnesses are assembled using our computerized
crimp-quality monitoring system and then circuit checked for the utmost
in reliability. A truly plug & play wiring solution.
WARNING: Some copy-cat pump kits use fuel resistant plastic wire which is not as
durable as Teflon. As well they do not have a new connector installed on
the end of the in-tank harness which forces the customer to re-use the
questionable old factory connector body. This has also let to some confusion
as to the proper polarity forcing some people to remove their tanks again
in order to fix the problem!
Quality Pumps
The Racetronix W1 pump assembly
is based on Walbro gerotor pump technology utilizing the most powerful
armature and gear set currently available. Walbro has set the industry
standard in high-performance in-tank pumps. 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 F-LS1 pump). This
positive displacement design makes high-performance Walbro pumps small,
light weight, quiet, efficient and reliable. |
