I am replacing the old Racor 500FE filter on my boat with a new Racor 500MA.
On the 500MA, the fuel ports are #8 O-Ring Boss (3/4 - 16 thread). However, I cannot find out what size ports the old Racor 500FE filter had. It almost looks like they are either #4 or #6 ORB, but I am not completely sure. For all I know, they are some sort of BSPP thread.
Since I don't want to disassemble everything to find out that I don't have the correct fittings, I was hoping someone might be able to answer the question. Thanks!
