Fuel filter for 87-91 blazer question.

[85 Jimmy]

The fittings for the fuel filter on a TBI blazer, do the have o-rings on them like the fuel sending unit does or is it just straight threads? The filter for reference is an AC Delco GF652

When I swapped to TPI I ran braided stainless from the tank to the fuel rail with -6 an fittings. I'm currently running a Russell filter, but want to swap to a fuel filter that I can get from any parts store. So I need to get adapters to go from -6 an to 16mm x 1.5 and need to know if I need the o-ring type or not.

Iirc, mine has 1 o-ring and 1 flare fitting (presumably to keep you from installing it backwards).

Been awhile since I replaced mine,but I seem to remember it would only go in one way,but they do have a flow arrow on them

After watching a few YouTube videos, it looks like both sides should have o-rings. Also, after looking at the filter I have, both sides seem to be the same.

Yep, what I recall as well. Both ends are "saginaw" flares.
