DmaxStore put together this ultimate fuel filter head package, combining all of the upgraded fuel filter head accessories into one easy to buy kit. This fuel filter head assembly eliminates the heater wire from the head that is common to leak on the older style filter heads. We also threw in all of our upgrades for the filter head, including the aluminum bleeder screw, WIF plug, and the filter head spacer. Lastly, the Racor coalescing filter system inside has up to twice the life and improved water removal in all blends and types of diesel fuel when compared to other paper media filters.
