Review: FIT my Simpson with a Honda motor!!! - I have an excellent Simpson w/Honda motor Power Washer that I bought either from Sam's Club or Costco. These injectors are brass (light metal) and somehow, something hit it while stored over winter. It was a pain to extract the threaded part, still in the machine, but once I did this fit like a glove!!! The problem was that everything had fitment for Briggs and Stratton, etc... NOTHING for Simpson/Honda. I imagine that the big box house sold a ton of units so if you are in my boat and needing a replacement injector, this worked well for my unit!
Review: Works with most pressure washers, easy to change. - Absolute perfect fit for my Troy-Built 2800! Takes less than 10 minutes to change. It includes two extra small Orings. Installation tip: look inside the brass fitting, the small Orings are already installed, they send two spares for future use. No need to scrunch that tiny Oring inside. Just remove old fitting, ball and spring. Take the new fitting, drop in the little ball, insert spring with small end against the ball, then re_attach it back on the pump. Do not over-tighten. Your done! Instructions are exact and correct, their help desk responded in 6 hours. I’m willing to bet this fitting fits a majority of major retailers pressure washers with a vertical shaft motor (pump is on the bottom). A+ seller!

### ⭐⭐⭐⭐ What to do with the O-ring
*by N***G on August 30, 2025*

The instructions were not clear on what to do with the extra O-ring. It looked like it was supposed to hold the spring in the center of the fitting the device get screwed into. So i carefully put the O-ring in place and screwed in the fitting. It works!
