The rebuild kit I picked up for my Carter YF 787s was only $16.00 at my local Oreillys
Its a Walker kit #15306A. I dont know if its the same kit for a 2100s

Its on the shelf, not to expensive and no shipping cost.
The pumps don't seem to last very long, either due to the fuel or the type of rubber used.
Good Luck
