Marauder 25 cal leaking

[drsquall]

Hello,
My marauder started leaking out the very end of the fill fitting. It has never done it while I used a hand pump but I bought portable compressor and it does after I fill it sometimes. I can sometimes reattach the fill line and fill it up and disconnect and it will stop. Today however it would not stop and my gun is empty. What do I need to do to fix it?

Thanks
Jon

I would give the Crosman Customer service a call. They have all the parts needed to fix it.

It is probably just the O-ring on the fill nipple check valve. It can be an easy fix. Just remove the fill nipple, pop out the check valve and replace the O-ring. Clean everything and reinstall the check valve. Then fill nipple.

The other option is it just buy a fill nipple adapter with fill nipple installed. It is just as easy and lower risk. That is usually what I do.

Ok I will reach out to Crosman for parts

@drsquall I had that happen on a Marauder pistol. I was told by a Crosman technician to place a drop of some sort of silicone oil (iirc) down into the fill nipple. I was more comfortable replacing the nipple so I got a new one and installed it. Haven’t had any issues since.
