Fragola 491989-BL Black GM Fuel Rail 3/8" Clip Type To AN -6 Male Adapter Fitting

These adapters are for stock LS style fuel rails. They adapt the factory 3/8" feed fitting to #6 AN. They are proudly made here in the USA from a solid piece of 6061-T6 Aircraft grade aluminum. This size usually fits the feed side of an older two line system. It will fit most GM applications with the smaller 3/8" hard line. If you have an older LS1 or a truck, your application requires an inlet and return.

Push on style from Fragola. You simply push this fitting onto your 3/8" fuel rail and it clips over the hump on the fuel rail, sealing with two o-rings.
