MPR Target Air Leak - Need Help

[Scrench]

My white MPR Target version leaks air from where I screw the air tank onto the receiver. I'm thinking there should be a rubber seal there but don't see one. I can't find any info on the web that tells me how to fix it. Am I correct in that a seal should go there that is now missing?

Thanks,

Scrench

I'm an idiot. There is an O-ring in a recessed slot at the base of the receiver where the air tank snugs against it. The O-ring size is 7x2mm. I accidentally put in a 8x2mm ring and it still leaked. A 7x2 fixed the problem.

If your stuck for seals Julian Bond will have them in the sales section.
