Retro valve leak

[Wayne]

OK so I picked up a retro valve and it has a leak out of the side of the gun. The tiny hole found on the left side to be precise. Which o ring is this usually attributed to? I ask because I am running low on orings and can't replace everyone. Thanks.

That would be your reg valve assy orings. #30

[Wayne]

I don't remember but are those included in the parts kit.

[Ando]

Yes.
