They need to be Viton 90. I think the size is -906.

Sometimes. The other option is to search for an o-ring dealer near you, but they will likely be a M-F type place.

If you're in a pinch, a regular Buna N o-ring will work for a while. Using loctite 680 on the threads will also help if you make sure the threads get spotless clean and let it sit for at least a few hours before start up.

If they're in stock and the kit contains the right size, then I'd say yes, they will probably work. They don't list the Viton rating, but they should do just fine.

Kind of pricey though. If they are -906 o-rings, then you can get them much cheaper. O-Ring, Viton, AS568A-906, Round, PK25 - O-Rings - Supplies - 1WHN4 : Grainger Industrial Supply

Of course, if you need it now, then around $8 on a Sunday is hardly worth complaining about. Might be wise to pick up an o-ring kit from Guzzle though so you're ready for next time something pops up.

Those are the super duty HPOP o-rings. I'm not certain it's the same for the OBS. Bob would know, but I don't know if he would, or should share.

Others will probably know also. Just for reference, here's Alan's o-ring chart from the SD 7.3 Powerstroke O-Ring Chart

This is what i found does this sound right ?

For the -6 fitting (the ones on the HPOP) the o-ring is a "-906" (.468" id x .078" wd).

-906 (dash 906) is what I linked above at grainger, so it would make sense they are the same as on the SD fittings.
