FASS 17-19 Duramax L5P Crew Cab Short Bed / 17-23 Crew Cab Long Bed Drop-In Series Fuel System

THIS IS NOT A LIFT PUMP! This is an air separation/filtration system that utilizes your factory in-tank lift pump. ATTENTION! The Drop-In Series System for the L5P Duramax was designed to mount in the OEM water separator location and may not work with aftermarket fuel tanks that have greater fuel capacity than the stock tank. YOU MUST VERIFY THAT THERE IS ADEQUATE SPACE TO MOUNT THE DROP-IN SERIES FASS SYSTEM IF YOU HAVE AN AFTERMARKET FUEL TANK!!
