FORM INST500ITFP

NOTE: We recommend that the installation of this fuel pump be 

done at a qualified and licensed installation center by a licensed/

certified technician. Installation of this product requires handling 

of gasoline. Ensure you are working in a well ventilated area with 

an approved fire extinguisher nearby. Extinguish all open flames, 

prohibit smoking and eliminate all sources of ignition in the area 

of the vehicle before proceeding with the installation.

WARNING:

You are about to start working on the vehicle’s fuel system that when 

opened, can be highly flammable.  DO NOT ATTEMP THE WORK 

WHERE OPEN FLAMES AND OR POSSIBLE SPARKS CAN OCCUR OR 

ARE PRESENT. Extinguish all open flames; do not allow smoking and 

or any other type of flame ignition in the area where the vehicle is 

being worked on before proceeding with the installation. A working 

Fire Extinguisher must be present/nearby during the installation.

Always remember that the fuel system is under pressure even if 

engine has not been started during a lengthy period. Safely relieve 

all pressure before attempting to open the fuel system. Refer to the 

vehicle’s service manual for the proper procedure.

Vehicle Electrical System Check

• Before attempting to install this fuel pump, you must check the fac-

tory wiring for the proper wire gauge thickness that supplies power 

to the pump.  The factory fuel pump wiring may not be sufficient to 

handle the current draw of this high performance fuel pump.  We rec-

ommend the use of an aftermarket wiring kit.  Please refer to page 4.

• If you use the existing electrical pump connector in your tank, you 

must ensure that the polarity is correct for your new pump. If neces-

sary, re-pin the existing connector or use the included connector. If 

you use the new connector included in the kit. Make sure to solder 

the connections and use shrink tubing to protect the connection.

• The ACCEL THRUSTER 500 pump is the same physical size as 

many OEM in-tank pumps. This does not necessarily mean it is 

suitable for a particular application. Consult the ACCEL application 

guide first to determine if a THRUSTER Pump is recommended for 

your car, before proceeding with installation.

• The fuel pump basket or integral in-tank baffling may require 

modifications to allow sufficient inflow of fuel from the main tank. 

Failure of the basket or baffling to remain full of fuel during high 

engine load may significantly diminish the pump’s performance.

• Installing a new factory down-stream filter is HIGHLY recommend-

ed when installing this pump, and it should be monitored and ser-

viced as needed to ensure fuel pump performance and service life.

• Your new ACCEL Fuel Pump is only one component part of your 

automobile’s complete fuel system. You must ensure the complete 

fuel system is up to the task of supplying fuel to your engine for 

the specific horse power needs to avoid severe engine damage. 

Contact ACCEL if you have questions regarding your complete fuel 

system needs and requirements.

Note: Failure to follow the above recommendations may result in 

fuel leakage, bursting of the fuel lines, poor vehicle performance 

and/or decreased fuel pump life!  Improper installation will void 

all warranties for this product!

CAUTION:

Compatible Fuels – Race Fuel – Ethanol – E85- E95

• Due to the dielectric properties of Alcohol fuels like E85, 

fuel pump service life will be reduced and filter maintenance 

increased. Be certain alcohol compatible filters are installed and 

frequently maintained.

APPLICATION INFORMATION

ACCEL has made available specific application information inform-

ing what known vehicles have a fuel pump form-factor that is com-

patible with the ACCEL THRUSTER 500 pumps.

Please find the application MML guide on our website at www.

accel-ignition.com under the Support tab.  Always check for prod-

uct instruction/operation updates on our website before installing 

the product.

INSTRUCTIONS

For those familiar with purchasing aftermarket fuel pumps for 

installation as a replacement for the stock fuel pump, selecting the 

correct THRUSTER 500 pump is easy. Note: P/N’s 75340, 75341, 75342 

and 75169 are configured as universal, in-tank replacement pumps, 

and feature the same form-factor (external dimensions) as 4 popular 

255 LPH fuel pumps commonly sold under P/N’s GSS340, GSS341, 

GSS342 and 111169 respectively. There are many applications where 

these common, 255 LPH pumps are used effectively in the stock tank, 

without major modifications, and those same applications may work 

as well with the new ACCEL THRUSTER 500 Pumps.

  To ease the determination of which ACCEL THRUSTER 500 pump 

may be used as an alternative, note that the last 2-digits of the 

ACCEL THRUSTER 500 Series part numbers correspond to the last 

two digits of the 4 common, 255 LPH pumps. For those that know 

which of the 255 LPH pumps will work in their tank, simply select 

the ACCEL THRUSTER 500 pump with the same last 2-digits.

For example, the 255 LPH GSS340 and the ACCEL 75340 will have 

similar form-factor and application.

  There are many applications where the ACCEL Pumps (and the 

same form factor 255 LPH pumps) will not work as a direct replace-

ment. In these cases it is likely that some modifications have been 

made to the tank, the internal basket or baffling, and/or the fuel 

level sending unit to perform the installation.

  ACCEL neither sanctions or approves any modifications be made 

inside the tank to install one of these pumps, and any modifications 

that are made are done so at the sole discretion of the purchaser/

installer, with no guarantee of pump performance, service life, or 

assurance of compatibility made by ACCEL.

Note: Flow tests are done in a test lab.  Length, inner diameter of 

fuel line/hose and amount of sharp bends in the line can diminish 

its flow rating.  As a rule of thumb, consider utilizing 85% of the 

pump’s flow rating as a safety factor/cushion. Always remember; 

the fewer bends in the line, the fewer 90 deg fittings used and the 

shorter the line is from the pump to the engine will allow for more 

fuel to get to your injectors.
