Shop Warning!
These Yanmar Injection pumps are very durable. If your pump failed then odds are that there is something wrong with your fuel. Please flush your fuel system with clean, fresh fuel & install a new filter before installing this new pump or you might end up with the same problem. Warranty does not cover pumps that are damaged due to trash or water in the fuel system. 

Shop Notes:
You will really want to time the pump after installing. The timing is adjusted by the number of shims under the pump (between the pump & engine). You can usually get the tractor to run by just using the same shims that were under your old pump but to get it to run correctly you will want to time it. Full timing instructions can be found in the link below:

Shop Notes #2:
Don't forget to bleed the air out of the system. See instructions on our bleeding fuel system article.
