For the past couple months, I haven't been able to get my MEP-016B started. Yesterday I tried again, and as I was operating the manual fuel pump lever, I heard a sucking sound coming from the fuel filter. Turns out, the bolt for the fuel filter housing that holds the lid on has stripped. Looking in the TM, I find that the housing is part number 149-2147 (44940), but there's no NSN. Googling those numbers so far has just given results that point back to the TM. Are there any sources for the filter housing? Since I'm having to replace the housing anyway, is there a good spin-on fuel filter base that will fit in the space?
