I am confused....
if the fram will fit on the engine provided filter head, (which the Fleetguard also fits) why won't the Fleetguard fit the filter head that the Fram will fit? Fram filters do not seem to be very well liked on this forum.
I do not know where to access a remote mount filter head, unless you are talking about Amsoil's set-up. Have you tried NAPA (that is the place I always try first) or Summit Racing?
