repaired the Excell bi-radial pressure washer

So more than the thermal fuse was leaking on my old pressure washer.  Replaced the thermal fuse and it was still leaking.  Apparently because of the bi-radial piston design it uses a "dead" hose to balance
pressure surges and it had worn a hole after 14 years of use.


It was the first item that popped up on Amazon parts search








new part

need to remove hose and outlet to remove shield to replace "dead" hose and thermal fuse

So now that the leaks are solved I can make a update on the foam canyon pressure washer switch.
