I've been using my moroso 3 qt oil accumulator for around 14 seasons now with no issues. Noticed recently that when I open the valve the oil gauge doesn't move like maybe there's not enough oil in the accumulator. when I take my oil level check plug out of the pan it's over full so long story short I think I've got a seal(s) bad in the accumulator. Tried a new high quality shut off valve and it didn't help. Has anyone ever tried and had good luck replacing seals in one of these? Moroso doesn't offer anything parts wise from what I've found.

You can take it apart and take the piston out. There is an oring on it that will be worn or just hard from age.

Any Idea on where I can get that o-ring and possibly a part number?

Believe it or not, I have been using Harbor Freights o-ring kits for years with no problems. They cost hardly anything and you can get them in Viton also. The pumps I use in my business run 6-8 hrs a day at 300psi and I have had no failures from their O-rings.
