The Lethal Performance / DivisionX mustang fuel systems are the most widely used, best performing return style fuel systems on the market. These systems come complete with everything you need to convert your car to a return style fuel system. These systems are also completely upgradable so later down the road if you need to support more power or a different fuel type all that's needed is a pump upgrade and you're good to go.
This system comes standard with pre-assembled Fragola PTFE fuel hose. This hose has a PTFE inner liner, stainless steel braid and a protective black vinyl cover so the hose will not scratch any paint or parts of the vehicle or engine. PTFE fuel hose is more durable than the standard hose and prevents fuel smell typically found when using non PTFE lined hose.We have used the standard Fragola pushlite fuel hose on several of our shop cars with both gasoline and E85 with excellent results and no fuel smell. If you would like the non PTFE hose please choose that option from the dropdown menu. If you decide to purchase this kit with the standard hose Lethal Performance will not be liable for claims of fuel smell after installation.
The Lethal Performance return style fuel systems come in two different ways. For the 07-09 cars we use a traditional style setup where the regulator is placed after the fuel rails. For the 2010 model however we use a deadhead setup which places the fuel pressure regulator before the rails and dead heads the fuel rails. We have used the system in both configurations with excellent results even in the 1250rwhp range on E85.
The fuel lines in this system come pre-assembled. Due to this, the installation of the system becomes much easier as you will not need to install any hose ends. With that said, the system is designed to be installed one way. If you try and install the lines in any other configuration then the one we designed it for you won't be able to properly install the system.
Lethal Performance is not responsible for any additional hose or fittings required due to custom installation.
Easy to Upgrade- If at any point you grow out of the system you're in and need to step up to the next system to support more hp all you need is the pumps as all of the systems are the same except for the pumps.

NOTES: 2005-2009 Mustang GT's and 2007-2009 GT500's to re-use their factory level sender. 2010+ GT's and GT500's use a different level sender than the 05-09 GT's and 07-09 GT500's. Due to that all 2010+ GT's and GT500's need to re-use their stock level sender with this hat and purchase the adapter to mate the level sender to the fuel hat.
