I have a foreman 2001 450 es and found this weekend after riding a small gas leak on the right side of the carb:
I would think it called the pump set part # 16048HM5L00
I see the leak by the rubber boot are there any replacement gasket or do I need to buy the complete pump?
ATV runs fine I did add some Gas Stabilizer a few weeks back 2oz for the 4 gallon gas tank
I don;t think it would harm the gaskets it is made for gas that the bike is stored for a month or two upstate in cold weather
I see there is 2 small screws that mount it too the carb: I wonder how hard is it to remove the pump or do you have to remove the carb: for this repair?
I was told just to make up a by-pass cover plate and to remove the pump from the body of the carb: redrill the cover plate and a gasket to seal it off.
I see honda get $75.00-to 85.00 buck for the replacement pump

 

You have to buy the entire primer pump,you can remove it with the two screws with the carb on the bike,there is a spring behind it,very easy to replace
