o-ring?

[ORayK]

where the fuel line hooks to the pressure regulator, there is what appears to be a tiny o-ring at the base of the "flange" on the fuelline where it seats in the regulator. Is this a true o-ring or something "Buick" and where do I get one? It's not leaking now, but I hate to be caught without a replacement.

Still available from GM...one you're looking for is the return line...might as well get some for the feed line too...I usually get about 10 of each to keep on hand...they tear up easily if you remove the fuel lines...

Return Line - 22516256
Feed Line - 22514722

Those are pretty much standard seals used on anything PFI as far as GM goes. You can get them at NAPA and AZ assuming a dealer doesn't have them in stock.

Here are some sizes listed in the GM catalog.
22514722= 7.35mm ID X 1.66mm Thick
22516256= 6.07mm ID X 1.30mm Thick
