Anyone here have a pressure washer with a Honda GX390 engine?

I have one and the engine runs great and it has pressure but the pump leaks water in some spots and water is getting in the pump oil. I am trying to figure out if I should just replace the pump for around 300 or so or if I can rebuild it for much cheaper. The pump is a general pump EZ4040

I would say buy a new one since that pressure washer is about $1200 new (think so...?) Anyhow I have the same setup and if mine were doing what your is then I would for sure get a new pump...? $300 is not that much for a new pump for one of those...

Only other thing you could try is a gasket kit for the pump...? Might save you a few bucks...?

I bought a new pump for 309 off Amazon and the square trade 4 year warranty for $18 more. I will buy a rebuild kit for the other one if possible

I would have gone the rebuild route, if you can wait to finish the work... tear it open and see if the rest looks good and it only needs a seal, then order the appropriate parts.
