    Tech MEP-802A MEP-803A Filters and Parts

    Howdy,

    MEP-802a and MEP-803a use all the same filters and such
    MEP-802A ONAN DN2M 2-cylinder engine (Lister-Petter LPW2) Liquid cooled diesel, aluminum housing
    MEP-803A ONAN DN4M 4-cylinder engine (Lister-Petter LPW4) Liquid cooled diesel, aluminum housing

    Oil Filter Spin-On (FILTER ELEMENT, FLUID NSN# 2940-01-154-5127 )

    WIX 51374, Napa 1374, works also (WIX 51348, NAPA 1348 ), FLEETGUARD LF3335, BALDWIN BT223, DONALDSON P550335, FRAM PH3614, PUROLATOR L10241, CHAMP PH2835


    Fuel Filter cartridge (FILTER ELEMENT, FLUID, CARTRIDGE NSN# 2910-00-099-5467 )

    WIX 33348, NAPA 3348, FLEETGUARD FF4012, BALDWIN PF-847, DONALDSON P13, FRAM C11941, PUROLATOR F53121


    Fuel Filter, Spin-On Fuel/Water Separator Filter (FILTER, FLUID NSN# 2910-01-376-5666 )
    True Military filter with drain connector 85285-F

    Alternate replacements, with bottom drain, but, factory drain with hose does NOT connect WIX 33472, NAPA 3472, FLEETGUARD FS1251, BALDWIN BF1226, DONALDSON P550248, FRAM P8043, PUROLATOR F64424


    Air Filter (FILTER ELEMENT, INTAKE AIR CLEANER NSN# 2940-00-934-7989 )

    WIX 42276, NAPA 2276, FLEETGUARD AF435KM, BALDWIN PA1690FN, DONALDSON P181050, FRAM CAK256

    When looking for engine parts and gaskets, always search for both
    ONAN DN2M or Lister-Petter LPW2 for 2 cylinder
    ONAN DN4M or Lister-Petter LPW4 for 4 cylinder
    Engines are all the same parts 2-cylinder or a little longer 4 cylinder. pistons, rings etc are the same.


    There are many other filters out there. The best is a quality filter for a good price.
