Umarex Fusion 2 O-Rings list?

My Umarex Fusion 2 first needed o-rings for the pellet probe / bolt. They sent me a whole new bolt which I had no clue how to put in. I removed the o-rings and swapped them to my bolt. My determination is 4.7 OD, 2.5 ID and 1.0 thick (.185 / .0984 / .040).

Now the INNER o-ring on the CO2 tube cap has failed (the middle screw-in piercer) and I need to know the size?

Can anyone help or direct me to a vendor that sells rebuild kits for the gun? Archerairguns only lists the outside seals or the whole assembly.

Wish I could find an exploded view with a complete list of parts!!

Thanks .... Got to keep the wife's varmint gun working!! I think I need to move her into PCP like myself.

It should be under warranty if it's within one year from original date of purchase. I would contact Umarex USA to request the parts you need because the Archer parts may not fit which may only be specific to the Fusion 1 that may have a different Co2 cap.

This may be another option if the gun itself can use 88 gram Co2 threaded directly into the gun probably less problematic if it threads in? Maybe they give you a real good deal if they don't have the replacement piercer cover you need. Search if the Umarex 15% discount code is still valid as well.
