Wix Fuel Filter P/N:33837
Keep clean, contaminant-free fuel flowing to your injection system with the WIX Spin-On Fuel Filter 33218, a heavy-duty (HD) filter that traps particles from the fuel before they reach downstream fuel components. It drops in as a direct-fit replacement for a long list of MACK medium- and heavy-duty trucks — including CM-, CS- and MS-series MID-LINER models, spanning the 6-7.8L, 6-9.8L, L6-5.5L, L6-6.2L and L6-8.8L engines — so check the "Vehicles it fits" section for the full application list.
If a clogged or restricted fuel filter is the cause of hard starting, hesitation or a loss of power, replacing it with this filter helps restore proper fuel flow. Made in the United States. Each listed application uses one filter.
