how can I find a longer filter that will fit the mating plate on a Onan gen set. The OEM filter is a Onan 1220645 and is 3.5" long. It is difficult to change due to lack of clearance of the shrouding. The gasket is OD.- 2.74" & ID. -2.37" with a 3/4-16 thread. I've been looking through the Wix interchange site but can't come up with anything with the same footprint but longer.
