GP Injector Rebuild Kit
I ordered several of these kits because they go bad so quickly. Unfortunately this kit has a ball that’s to big for my injector as mine has a metal ball bearing size ball and this was a larger plastic ball that comes in the kit, so I replaced the o ring and the spring, but used the ball I already have. This unfortunately didn’t fix my soap injection issue.

Money saver
Pretty easy to rebuild. Saves me about $20 on replacing the whole injector. Love that Pressure Tek actually stocks this unlike some other vendors.
