Umarex Fusion 2 HPA Adapter

[desertplinker]

Was wondering if anyone has used HPA with a Fusion 2 as it will accept the 88 g Cylinders.

I saw this one here > https://www.airgunnation.com/topic/umarex-fusion-2/
or you can also install a fill nipple on a 88gram and fill it around co2 max (<1500psi) with air.

Thanks that is what I was thinking some kind of tether set up but I don't know much about paintball stuff like what type of fittings and size and that kind of stuff.

I'd thought about it...but don't have one....just looking at pictures.

Looking at the few pictures of the Fusion II with 88gr. attached,amd thinking it won;'t be that easy.

Typical 88/90gr. AirSource tank is about 1.35" in diameter...and it comes pretty close to the barrel.  Typical current  13CI HPA tank is more like 2.08" in diameter. So basically  1/4" fatter "up" and 1/4" fatter down.

So am thinking a straight line type of mount wouldn't quite fit.  Would need to add a "drop down" type (QB79)tank block...add a stock cut/mod to deal with the low hanging fat tank.

Typical 88/90gr. type co2 tank is aboutn 8" long.   Typical 13CI HPA tank(with regulator) is about 9 13/4" long....plus the screwed on adaptor to AirSoruse length....call it 10 1/2"....so the triangular LDC whould have to come off.

It's not made to come off.

Do think folks HAVE done an HPA tank mod....but it doesn't look like it's "plug and play".

IVE used the 88 grams on some hpa projects , up to 2000 even.. 1800 is recommended.. a fill nipple installs nicely right at the end.. cheap , reliable , already threaded for the gun.. get this fill nipple , its already presprung inteernally , so ur all set

I should not have said 88 gram what I need is a bulk fill adapter for the end cap where the two CO2 carts would go, is that what this is Rob? My plan is to tether a small paintball tank set for 800psi.

next message sums up the misunderstanding

ok back on track , you have a Fusion 2 , NOT an rws850-2 .. MY bad..
SO those tubes are essentually xisico xs60 tubes as i recall , with a different endplug..Off the top of my head , Im not sure the valve is sealed to the tube .. thats the first thing to find out.. If it is , You can do a bulk co2/hpa set up at the front nipple.. Generally , if it bleeds 2 co2 carts, that means the main airtube is sealed.. Meaning , all you would need is the fill nipple i mentioned for 8 dollars, and a way to drill and tap that front cap of the gun.

[Rob M]

if you add the fill nipple to the factory cap , you can no longer pierce the front co2.. SO youd really want a seperate bulk fill cap.. the fill pressure iis limited by the original intention of the airtube , which is about 1000 psi hpa.. ( co2 on a summer day _

[desertplinker]

yes, I think same as QB CO2 rifles and yes the tube seals when you pierce the carts. They used to have a bulk fill adapter but no one seems to make them that I can find. I don't have the tools to drill and tap, would rather just buy a cap with nipple already installed.

correct. My tank will be 800psi output max.

well those 2 links should solve it

Dennis Baker AG has the fittings you need to go from 88gr to paint/ball regs BNA adapter 6 and one for the hammerli/ umarex 850 these converted my Umarex 850 to HPA

[Ribbonstone]

Don't think there is enough room under the Fusion 2 barrel for the 850 type "straight line" set up to work....might be wrong, but sure doesn't look like it from the phots of ones set up on 88gr. tanks.

[Bentong]

If all you want is to tether..you can source all from ebay or amazon/ Just put the slide check the other way to make it work.

[desertplinker]

I should have left the 88g out of the discussion. What I really need is the bulk fill cap on the end of the tube, forget the 88g, it's not in the equation, my fault.

[desertplinker]

I want HPA in the entire tube kind of like a pre plenum. Someone posted on another forum running a tether tank right on the end of the entire tube and shot string was more consistent then on CO2.

I'm not opposed to buying stuff from across the pond but the description I read on their site is what you get you still need to drill out to attach the nipple. the one I see at GMAC that has the nipple says currently unavailable.
