Injectors and injector pump

[Aurora]

Old 27’with yanmar turbo diesel....any product I can use to clean the injectors and pump? Thanks

There are scores of additives that claim to do this. And you’ll likely find folks who claim each one worked.
I’ve used Startron in the past and it seemed to have worked. There is also a Stanadyne product, Howe’s and fppf.
I would recommend NOT using Marvel Mystery oil but some claim that works.
Bottom line pick one made for diesel and try it.

American product I use over here - BG244 by BG products. I’m not one for snake oil but this stuff I found actually worked.
