The micron rating of the last chance filter would be the same as in the car
the injector came from or was used in. Find a filter with that micron rating
(the one from the car) and cut it open. Lay out the paper or wire media and
measure the square inches. Double that number and buy a filter(s) that have that
numberof square inches of media and AN fitting capability.
There is no application for hose barb fittings on an airplane or a
race car. Change the filters at annual.
Sintered bronze elements can be plugged solid by a dose of water. I would
not use them. This is race car stuff. My BD-4 hangs from the ceiling
unfinished.

Hi
Finn,
Since you appear to be uncomfortable with barb fittings, here are
the ones I used for over 10 years that have a screwed on fitting, never
had any problems. Replaced them ever 2 years, cut them open and
could never detect any trash in fuel system. I started with an AC
GF-481 which became hard to find and then switched to a more readily
accessible NAPA filter the GF652 NAPA FIL-3481. They do require the
Saginaw fitting and an "O" ring.
Fuel Filters:
OEM Auto Fuel Injector Fuel Filters (Two in
Parallel) Type: AC GF - 481
Pkg: 25056052 OEM:25055129 (or equivalent)
Replaced by GF652, NAPA FIL
-3481 Fittings: 3/8 Saginaw to AN6
Adapter, “O” ring required
Best
Regards
Ed

http://mail.lancaironline.net:81/lists/flyrotary/List.html Have you
searched for an inline fuel injection filter with NPT threads? You can use
NPT to hose barb adapters. Summit has one that looks like the NAPA all
metal filter several builders have used. It doesn't list filter media or
max psi on the site, but it might be worth a
look.
