Customer Question

2004 Mack. I KNOW there are two fuel filters on this truck. New husband doesn't believe me and can't find second filter. I can't ask my ex. Please help. I had this issue when the truck was first purchased (used) and cannot remember where we finally found the second one. Then and now the Mack dealers around me are zero help.

Here is basic Mack, it will have a primary filter and a secondary filter. Primary can be near fuel suction line, mounted on frame or can be on engine. See link attached.
