O boy what fun. Good pumps until they go out. A similar wale gusher has the lever going the wrong way.
I bought a rebuild kit and gave it a shot, then discovered because of all the spring tension I needed a special vice to hold it during reassembly. Either that or two pairs of oyster shucker's hands.
I tried to make a jig that fit in my bench vise but only ended up bending a screw and cracking the pump housing.
Happily, the AUD to US exchange rate is a lot better than US to CAN, so visa ended up crediting my account. O yeah, from Australia shipping was 70.00. The pump, 83.92. AUD
Their part number was RWB-519 Galley Foot Pump.
This was in late 2019, so you should probably reconfirm all of this, but rebuilding ? Tough
Good Luck,
Dave
