Sourcing seal kit for greenworks water pump?
I’ve been messing with a pressure washer I got from a neighbor that wasn’t working properly. Thought it was just the gun, but with a new gun I’ve confirmed the manifold is leaking. My engineer brother said it looked like the housing was actually in good shape and probably needed a rebuild. So the ports in the manifold are all ~15mm I’m assuming that is the size of kit I need but I’m just wondering if anyone can offer any guidance on what to replace or what to look for online specifically. It seems like the seals are basically shot, it flows like a sieve but no visible damage is present.
I attached one quick photo but I can take better pics if needed. It’s off a greenworks 2000psi electric washer. There are complete new pump heads available on eBay but I’d prefer to rebuild with a kit if possible.
