Customer Reviews


Lethal Performance fuel systems are by far the most widely used, easy to install and best performing systems on the market. With our drop in direct fit billet fuel hat and multiple fuel pump options we have systems for all horsepower levels and fuel types. Horsepower above 1600 and beyond 2000 can be achieved with pump choice.

Our systems come complete with everything you need excluding fuel injectors

Our systems come standard with Fragola pre-assembled PTFE fuel hose. PTFE fuel hose is more durable than the standard pushlite hose and prevents fuel smell typically found when using non PTFE hose.We have used the standard Fragola non-Teflon based fuel hose on several of our shop cars with both gasoline and E85 with excellent results and no fuel smell. However if you would like ensure that you have no fuel smell we highly recommend the PTFE hose which is included as a standard option. The Fragola PTFE fuel hose has an PTFE inner liner which is then covered in a stainless steel braid and then covered in a black protective vinyl coating. This prevents the hose from scratching any parts of the vehicle or engine. The hose ends are all black anodized for stealth look.

The Lethal Performance 99-04 return style fuel systems are designed as a "dead head" setup. This places the regulator before the fuel rails which we've found works excellent and we've proven it over the years both on the track and the dyno with all of the Lethal Performance project cars.
