when u pull the pump off the Kubota engine-does it have thin plastic shim underneath? dont lose it and if you send it off make sure to include it..the Stanydyne DB pump on the Case is a good pump Sonny you just need it freshened up with the updates they have for it..once again the ultra low-sulphur diesel doesnt supply the lubrication to the pump internals and they go bad more frequently..I usually get about 10yrs out of a DB2.
Absolutely do not do business with Diesel Care and Performance in Memphis Tenn, they bounced me around for 4months before getting my pump back to me..total BS..30days tops,very easy pump to rebuild..whats the total part number on the pump tag (on side of pump)
