    Does anyone happen to know what size it the vacuum port on the side of the Riva racing fuel pressure regulator for a seadoo rxt. I was changing my batt and accidental broke my fitting of my regulator?

    1/8" NPT male thread with a 1/8" or 5/32" nipple will work. A 3/16" nipple will also work if you can't find the smaller ones.

    You sure? I think 1/8 NPT is for the intake manifold... On the regulator it's smaller than 1/8 NPT...
