Well after doing 3 weeks of pain staking looking on the net and PWC wreck yards I couldnt find anything for my MSX 110. I was so upset that a simple $49 part was going to keep me out of the water so I modified the fuel rail just to run them. Needless to say I did more searching and found YES THEY DO MAKE PARTS. now mind you not all these parts will work but im sure 99% of them will. See the reason I say this is because these parts are for snowmobiles. But what I found out is that the motors for the MSX 110 and 150 are a weber motor. So I went from there and found from 2007-2011 Polaris FST snowmobile has the same motor.

Its a different part number but by the looks of it she looks the same. I know because Ive had both my MSX 110 fuel rails in and out 30 times trying to mod them. I hope this helps some out! I noticed the lack of people posting on here to help others.
