Perkins fuel filter adapter
 

Received my spin-on fuel filter adapter today. Just what I was
looking for. Interestingly, it is not any sort of custom unit. It is
a standard part made by Parker and fits any CAV filter mount
on a number of different engines (Perkins, Ford, Volvo, SAAB,
etc). Thanks to all that offered advise!
