The factory fuel pump wiring may not be sufficient tohandle 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, youmust ensure that the polarity is correct for your new pump. If neces-sary, re-pin the existing connector or use the included connector. Ifyou use the new connector included in the kit. Make sure to solderthe connections and use shrink tubing to protect the connection.• The ACCEL THRUSTER 500 pump is the same physical size asmany OEM in-tank pumps. This does not necessarily mean it issuitable for a particular application. Consult the ACCEL applicationguide first to determine if a THRUSTER Pump is recommended foryour car, before proceeding with installation.• The fuel pump basket or integral in-tank baffling may requiremodifications to allow sufficient inflow of fuel from the main tank.Failure of the basket or baffling to remain full of fuel during highengine 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 yourautomobile’s complete fuel system.

Improper installation will voidall 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 maintenanceincreased. Be certain alcohol compatible filters are installed andfrequently maintained.APPLICATION INFORMATIONACCEL 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 installingthe product.INSTRUCTIONSFor those familiar with purchasing aftermarket fuel pumps forinstallation as a replacement for the stock fuel pump, selecting thecorrect THRUSTER 500 pump is easy. Note: P/N’s 75340, 75341, 75342and 75169 are configured as universal, in-tank replacement pumps,and feature the same form-factor (external dimensions) as 4 popular255 LPH fuel pumps commonly sold under P/N’s GSS340, GSS341,GSS342 and 111169 respectively. There are many applications wherethese common, 255 LPH pumps are used effectively in the stock tank,without major modifications, and those same applications may workas well with the new ACCEL THRUSTER 500 Pumps.To ease the determination of which ACCEL THRUSTER 500 pumpmay be used as an alternative, note that the last 2-digits of theACCEL THRUSTER 500 Series part numbers correspond to the lasttwo digits of the 4 common, 255 LPH pumps. For those that knowwhich of the 255 LPH pumps will work in their tank, simply selectthe ACCEL THRUSTER 500 pump with the same last 2-digits.For example, the 255 LPH GSS340 and the ACCEL 75340 will havesimilar form-factor and application.There are many applications where the ACCEL Pumps (and thesame form factor 255 LPH pumps) will not work as a direct replace-ment. In these cases it is likely that some modifications have beenmade to the tank, the internal basket or baffling, and/or the fuellevel sending unit to perform the installation.ACCEL neither sanctions or approves any modifications be madeinside the tank to install one of these pumps, and any modificationsthat are made are done so at the sole discretion of the purchaser/installer, with no guarantee of pump performance, service life, orassurance of compatibility made by ACCEL.Note: Flow tests are done in a test lab. Length, inner diameter offuel line/hose and amount of sharp bends in the line can diminishits flow rating. As a rule of thumb, consider utilizing 85% of thepump’s flow rating as a safety factor/cushion. Always remember;the fewer bends in the line, the fewer 90 deg fittings used and theshorter the line is from the pump to the engine will allow for morefuel to get to your injectors.ACCEL Thruster 500 Fuel PumpsPART NO. 75169, 75340, 75341, 75342INSTALLATION INSTRUCTIONS |
