It comes with the fuel pump. Sherco sells them individually. Zipty has metal ones, but I would ask them if they fit your 610.
The plastic one from txc250/310 works just need to make a clip/ or clamp to make sure they don't come out.We have both in stock. ; metal or plastic.
Plastic try Ryan Young products http://www.rypusa.com/ Use Sherco part 0805 $42 plus shipping. I broke my plastic elbow and replaced with the Sherco part and its a perfect fit. Here is a link for another approach http://www.advrider.com/forums/showthread.php?p=8664047 Whether you go with metal or plastic you can remove the old part like the guy in the link above did.
Could you give me some advice how to remove the broken plastick part from te fuel pump? it\s stuck...i cant take it out
Put something on metal so not to gouge it, lock some vice grips on the plastic and with a screwdriver pop it out. Cantilever method.
