Dumb question, does a generation 1 marauder 22 caliber have set screw in the barrel band? I have a slow leak and I'm thinking the the valve o-rings need to be replaced, I've replaced all the other o-rings and I still have a slow leak. Tried to remove barrel band today to try to get at the valve, but it appears there are no set screws at the top or bottom of the barrel band. please advise.

Barrel band has TWO screws than anchor it to the filler housing.
The 118 o-rings used to seal the MAIN TUBE parts ( Fill cap, gauge manifold , valve ) are one potential leak. The fill foster itself uses a polyurethane 006 on the bobbin within the fitting and over time absolutely breaks down & leaks.

Do not overlook the gauge itself.
Put some bubbles down there, especially near the weeper hole in the rear.
Put a balloon over the muzzle over night.
Inflate?
Bad poppet or o-ring inside the valve..

My gen one marauder had a leak like you are talking about and it was the valve steam it had a very small chip in the sealing edge do no if it the same thing that is wrong with yours but worth a look

did you check the fill valve threads? they can be a bugger to stop from leaking if they are leaking.

I'm pretty sure I have a leak around the valve orings, (I've replaced all the other rings). Do I have to remove the barrel band to remove the valve orings? That's why I originally stated this thread.Please remember my initial issue about having no sets screws on the barrel band. Thanks

Dark,
I have 2 Gen1 Marauders, one I have set up for Field Target competition, and is a nail driver.
The barrel band is attached to the threaded end piece at the end of the air tube. This end piece also has the Foster fitting screwed into it. This end piece should be just hand tight, and a little extra. The barrel band must come off in order to remove the end fitting. If you need more clarification, I tear down and reassemble a Gen 1 Marauder on my U Tube Channel, Field Target Tech. The issue that you have in removing the barrel band is odd.....it is held in by 2 small hex grub screws that are not visible. There are 2 small holes in the bottom of the barrel band that house these 2 screws. This is better seen in the disassembly video, the assembly video I edited a portion of the barrel band install.
Also, if you look at the Marauder rebuild video, I use a tool by Steven Archer of Archer Airguns to assist in the valve getting past the holes without damage. I highly recommend this tool, and I wouldn't rebuild my Marauder without it. Check the videos out, and get back to us on what you find.

I highly agree with Tom on the gauge port hole block off tool by Archer Airguns, it’s too easy to nick or kink the o-rings without it. Own one myself, works like a charm.

I think I found the leak, finally. It was the o-ring in the fill adapter assembly in the air pressure tube. Been holding steady for 2 days at 3000 psi. Thx and wish me luck. dark
