OK, so the FL1A and FL300A filters have the antidrainback valves. Went by AutoZone to check stock and prices.
FL1A they had, $3.49. Not bad. It's longer than the type I use, and I don't know how it'll fit in there.
The FL300A they did not stock. The FL300 was there, at $3.29, and it is the same size as the type I now use. (Fram PH43, longer than the Mann OEM size) So now how do I find out if the FL300 has the antidrainback valve? I can't tell anything by trying to look down in there. Is there another way?
Thanks all you patient readers.
