Replace screw if broken. Photo is not of the original spring. The original spring had corroded and broken into 50 pieces. The spring doesn’t have to be a perfect fit, just has to hold the part in place. The original spring was approx 6mm wide, 20mm tall and 0.5mm thickness wire.

do you know the replacement part numbers just in case?
The replacement parts are not listed in the manual and not available for sale. Hence this workaround.
what type of spring did you replace it with?
Random screw I found from a 3D printer part. Size and shape were both different than the original spring. As long as the dimension are similar to 6mm wide and 20mm tall, it would work. The spring I used was not 6mm by 2omm but close enough that it worked.
Replaced and still leaks. Tried replacing o ring and still leaks.
