This kit is to add an inline Filter, includes 88mm FORE Filter with billet bracket, pre-made 8AN lines and the adapters to tap into the fuel line on the vehicle back by the gas tank. The internal filter is the Stainless cleanable filter, and of course E85 compatible. We designed this to be installed when removing the factory filter from the jet-pump module on the return-less configurations especially when E85 is being used. This gives you injector protection at a better rate than factory, with more flow which helps some with pump pressure. In the future if you require a full return configuration, just remove this and relocate as it's the same filter used in our full return systems.
