I used my last Bosch fuel filter this week (#311 133 511 C) and it appears that part is NLA. I see that round filters are supposedly replacement options but I am hesitant to trust them. Does anyone know of a vendor who might have the correct, discontinued filter or a suitable, spec-correct replacement?

the round Mahle filters are just fine, the square ones are still available

Let me look I might have a real Bosch left. I do not like the aftermarkets because the do NOT lock in to place. You end up using a zip tie to keep them from moving.

The square fuel filter(s) that are shown on your internet page are all for later model fitment (small/large) connections, rather than the same size connections for the early cars.

early fuel filter,,,,,,,

Got 3 coming next week. Correct for early cars.
