18 h.p. FD(L)-11 thru 15F, (1957 thru 1961);

The 1962 model series QD and FD engines use a new fuel filter, part #378576, which has an improved filter element of saran plastic similar to the filter elements used in 40 and 75 h.p. engines. An additional change is a relocation of the fuel outlet passage in the body and nipple assembly which provides for an improved flow of gasoline through the filter with the new filter element.
The new filter assembly will also be serviced on the older engines listed above. However, because of the change made to the body and nipple assembly, the new filter element cannot be used in the old filter and vice-versa. Therefore, whenever the old style filter assembly, part #377599, or the old body and nipple assembly, #376836, require replacement, the new filter assembly complete, #378576, must be installed. Thereafter the following detail parts must be serviced as required. These parts also appear in the parts catalogs for the 1962 QD and FD engines.

Correct your Master Parts Price List and other applicable records to show part numbers 376836 and 377599 superseded by 378576. This supersedure, however, becomes effective only after Parts Distributors' stocks of old style parts become exhausted. Until such exhaustion occurs, the old style parts are still serviceable on those engines requiring these parts.
