Can you find a local Kubota dealer?
JohnI don't know where Shell Point is, and we have an M25. I know I can find the M25 Kubota crossover number from our C34 website, but never heard anyone ask for an M18.The related link goes to Kubota Equivalent on our message board. One post says it's marked on the side of the engine. Give that a try.Try this link, too. If this doesn't work, go back to the related link, and use the SEARCH feature at the top, type in equivalent, and scroll down to Kubota injector numbers. Lots of good tractor sources there.http://www.c34.org/phpbb/viewtopic.php?t=978&start=0&postdays=0&postorder=asc&highlight=equivalentIf you can find a local Kubota dealer, take your old one off and bring it in.My difficulty is that the Universal dealer is right down the street and they don't sell a lot of tractors in San Francisco anymore. ;DYou're right about the outrageous prices for "marine" versions of exactly the same thing.Stu
