We have updated our filter bases on for our non competition fuel systems to really dial in on the needs of this customer segment. These bases feature vacuum ports when placed pre pump and pressure ports when they are placed post pump. The arrows are also placed on the side of the base to show the direction of flow, which should be towards the engine. The in and outs are also labeled so there can be NO confusion.
Mounting bolts are 1/4" x 20, inlets are 6 ORB and the pressure ports are 1/8" NPT. The threaded nipple is a stainless 1-14" thread that accepts most common fuel filters on the market for diesel pickups.
Each base will come with 2 pipe plugs for the ports if they are unused.
