TREperformance has been manufacturing our own 255, 300, and 340 LPH fuel pumps for over 10 years. Do not be fooled by other companies who claim to have tested their pumps, we have each fuel pump, sending unit and housing tested before shipment. Have confidence in our products, we have sold over 100,000 of these fuel pumps and have had the flow tested by RC Engineering to verify the output. Our fuel pumps flow very similar to other pumps but they DO NOT have the loud, annoying whine of those pumps, and TREperformance fuel pumps are nearly silent when the vehicle is running. This makes our high performance 300 LPH pumps perfect for performance cars up to 700hp.

TREperformance Fuel Pump Guarantee:
TRE in-tank and external in-line fuel pumps have been tested to perform for many years even in heavily driven applications. We back our fuel pumps with a 1 week 100% money back guarantee, less expedited shipping, and a 1 year free replacement guarantee! We rarely have issues with our pumps, and you will not find a guarantee like this from other fuel pump manufacturers. If there are any problems when you receive your pump, just contact us within 1 week of receiving your fuel pump in the mail and we will either replace the pump for you, or refund your full payment less any expediting shipping fees. In addition, if your pump is defective or broken we will replace it free of charge anytime within the first year! However, make sure you clean your entire fuel system including the fuel tank before replacing a fuel pump, failure to do so will void the guarantee. Just contact us via email to receive return information. No returns are accepted without an RMA number. Our pumps are manufactured according to strict guidelines in order to maintain ISO 9002 and ISO/TS 16949 quality system certifications.

Boosted applications that see higher fuel pressures can still make 650 hp with this pump, but not when over 90 psi because the fuel heats up and can cause problems. Also, a fuel pump can't pump when it doesn't get enough voltage. If you are running high horsepower in the 500+ range you should upgrade your wiring and relay to support your new high flow fuel pump properly or your fuel pump may suffer low flow rates due to low voltage if your stock wiring is too thin and relay too weak.

Save some money and try one of our pumps. We back them with a 1 year warranty!
