Questions
This is different from the one I removed. I believe I have the Whale Gusher Mk 3, I previously ordered and installed the pump rebuild kit which fit fine. The gaiter I took off is taller and the hole is offset and angled. Is this indeed the correct one?
I think it’s likely the correct replacement. The old one is probably stretched and the angle of the hole from it forming to the pump lever receiver while at rest. My MK 3 kit looked just like your photo and fit perfectly.
