Review: Specs seems about spot on. 5.7 gpm at 3200 psi. - I've been using this pump for about 2 weeks now. Roughly 3-4 times a week for about 45 minutes each time. I added full synthetic 10w-30 oil since that is what I had. This pump replaced my AR RKV 4G36 pump. It fit perfectly on my Honda GX390. Removal of old pump & installation of new pump took all of 5 minutes. I was really curious to see if the flow rate was correct or not so this is how I tested it at 3200psi. I have a 15 gallon steel drum. I added 3 gallons of water inside the steel drum & marked it with a sharpie. Stuck my wand with a turbo nozzle in the water. Set my timer for 1 minute. Started my pressure washer. Verified the pressure was set at 3200psi. Pulled the trigger. During the flow rate testing, my pressure gauge read 3000psi. When my timer went off, I let go of the trigger, pressure went back up to 3200psi. I set my motor throttle to idle for about 15 seconds then turned it off. I disconnected my wand to let the water flow to cool the pump while I start removing 1 gallon of water at a time. I removed about 5.5 gallons or so during my testing. I say or so because I was using an old milk gallon jug I was throwing away. You are probably wondering why I was cooling the pump after a 1 minute test. In reality, I got everything ready to do the test. Then I pressured washed for about 30 minutes. When I got done, I set my timer for 1 minute & started my test. You can't just turn off your pressure washer pump off and not cool it down. That will ruin any pump quickly. I also run my pump at 3000psi & not at max of 3200psi. The real question is, will this pump last as long as my other pump did of 6 years. That is the real question. Quality seems good. Sooner or later, I will rebuild my AR pump to have a backup.
Review: You get what you pay for. - I knew this wasn't going to be the best pump. Most with specs like this will be at least $800. This pump lasted 4 washes. I've been washing for over 30 years and know how to properly treat a pump. Sorry i skimped.

## Questions & Answers

**Q: Will this pump fit on a honda gx390 motor**
A: If you have a 1" right handed hollow shaft. Also the bolt pattern is 3 1/4" at the top and at the bottom of the mounting pattern is 4 1/2".

**Q: This part fit my pressure washer?**
A: Depends on your pressure washer.  There appears to be a standard for attaching to engines, so if your engine is about the right horsepower, it will likely fit.  I had an off-brand 13 HP engine and it fit perfectly.You can check the bolt pattern and shaft size and compare to yours.  If it looks close, it is probably the right match.Be aware that this pump requires 13 HP or more to get to the specific pressure/flow rate.  My engine starts slowing down before I can get the rated pressure and flow.  That is good, it means I am getting everything I can from the pump!

**Q: This part fit my pressure washer?**
A: This pump has a 1" shaft and the bolt pattern is 6 1/2" diagonally from center to center and 3 1/4" across on the short side. If your existing pump matches those measurements and the PSI and GPM of your unit does not exceed 3200psi and 5.7 GPM then it should work!

**Q: Will this pump fit a honda gx 270**
A: U have to check ur shaft size ,I believe it fits your perfectly, this pump it's very powerfull
