Repairing hairline crack on pressure washer?

[M.alex]

My water pump has a hairline crack on it.

I can't weld it because it would damage all the internal seals.

I tried jb welding it, but the water poked holes through my repair (@2200psi)

Is there anything that's water proof and could stand up to that much pressure? Some really super duper form of epoxy? :dunno:

Might be worth tearing it apart and throwing a quick weld on it
