Instead of buying an entire new injector I want to just replace the orifices. They get blown out over time which alters the final mix ratio, and they’re easy to replace. I know that they can be had but sourcing them is somewhat difficult. Flowpro has a kit that clips onto their bypass but I don’t want one of each, I want a sack of 1.8 & 2.1’s. I suspect Dultmeier has them but their website is so difficult to search/navigate.
Anyone know where I can order some at a reasonable price?
Well, you can certainly do that but you are spending money on a $19 part. An injector rebuild kit is like $9. General Pump Injector Rebuild Kit
Now, if you want just different sized orifices, there lots of them around. Here is just a quick google search
A lot of people keep an air can and blow the injector out, cause the ball will stick sometimes. Just keep a few injectors on the truck, they are known to go bad often. I keep 3 on the rig and I am just a part timer. Make sure to always rinse your line out with water to extend the life of the injector and other parts.
On a side note, there is a tinkering fella on this forum who claims to have the greatest injector of all times @dperez
