AAA Pumps 90038 Horizontal Triplex Plunger Replacement Pressure Washer Pump Kit, 3800 PSI, 3.5 GPM, 1" Shaft, Includes Hardware and Siphon Tube, for Industrial Gas Powered Machines, Black

Easy to install. Matched right up with the old pump. Working as should.

Fits perfectly on the dewalt 3800 PSI power washer

I had an old pressure washer that sit for 10 years with a bad pump. I was able to clean up and revive the 9 HP Honda and picked this pump, knowing it was rated at 800 PSI higher than the OEM pump. The pump works well with plenty pressure. A 0-degree red tip pulls hard on the engine. I reduced the pressure but I would not use this pump with a smaller engine. I wish it has a valve for the chemical injection line, like the OEM pump. This pump is more powerful than any of the pressure washers I have owned in the past.

Only have had this pump for about a month and already is going bad

Bought this pump replacement for my Dewalt pressure washer. Replacement was simple. Used it very infrequently and for basic homeowner tasks. One day I went to use it to wash off the driveway from mulch and topsoil residue and just after beginning to use it I heard a loud pop sound. Pressure dropped and water was spraying out of the area where the hose connects to the pump. At first I though I blew a hole in the hose but later I realized the brass housing itself split. There is no other explanation than it was a bad casting of the brass. It simply should not do this. So now I’m faced with spending another 319.00 for a replacement. On top of that, because of where the split happened ( right at the hose attachment point) my house is permanent stuck in the fitting. Mind you this hose is literally weeks Old because my old one did blow out from use and sitting in my barn in between uses. So I’m also forced to buy a new hose as well. Just very frustrated and disappointed with this Amazon product.

Works good not as strong as original! Bolted right on. Fast shipping was great!!

This was a replacement for the one on my Honda engine. Another review said this pump is at the top of my engine’s capability. But it fit well, and it boosts the performance of the old pump considerably. Only warning is to be careful with the mounting bolts on the Honda engine. Easy to cross thread in the soft engine housing metal. Another warning, be sure the water connections are oriented correctly to work with your power washer.

Fast install works great on dewalt 3800 psi with Honda 270 engine

Worked as advertised.
