Lethal Performance 99-04 2V Budget Return Style Fuel System. The best selling, best performing fuel system kit on the market!Budget return fuel systems are intended to be used with STOCK fuel rails. Does not work with aftermarket fuel rails.
Lethal Performance and DivisionX have done it again! This time we're going to change the way the fuel delivery market works by offering our customers the ability to go return style but without the entire cost of a full return style fuel system. Even better, with this new budget return style system you'll still utilize the stock feed line, stock fuel rails and the stock fuel tank. This system comes complete with everything you need. Just install it and get your car tuned for the return style setup and you're good to go.
NOTE: This system comes standard with Fragola PTFE fuel hose. PTFE fuel hose is more durable than the standard 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 we do recommend the PTFE hose which comes standard to ensure there's no fuel weep or smell.
How's it work?It starts with a DivisionX billet fuel hat that houses (2) return style fuel pumps. The fuel hat installs in your stock fuel tank. Then we use the DivisionX hat-to-stock line adapter to connect the hat to your stock feed line. The next piece is a industry changing adapter that installs a DivisionX two port fuel pressure regulator onto your stock fuel rail. Included is a 100psi liquid filled mechanical fuel pressure gauge, vacuum hose and t-fitting which allows proper installation of the regulator. From the regulator we provide a PTFE lined -6an return line which returns the fuel back to the tank through the DivisionX fuel hat. The last piece of the kit is our famous Lethal Performance Plug and Play dual return style harness which features (2) 40amp relays, (2) 20amp fuses, Fusible links for the power distribution box connection and our OEM 6 pin connector which plugs directly onto the 6 pin connector on the fuel hat making installation a breeze!
If you're unfamiliar with a return style kit here's how it works.
The fuel pumps are wired to run full time. Fuel pressure is set by the mechanical fuel pressure regulator. The excess fuel bleeds off the regulator through the return line and back to the tank. In this system we use a boost reference regulator. That means that for every 1psi of boost the regulator see's it's going to mechanically raise fuel pressure by 1psi. So if you start with a base pressure of 40psi and make 20psi of boost you'll end up seeing 60psi of fuel pressure when in full boost. What's great about a return style fuel system is that it's easy to tune, doesn't use any returnless style electronics and works great for both street and track applications. We run return style systems on all of the Lethal Performance project cars over the years with great success.
