Interesting...I'm not sure how old the Rule
is but I have had to patch the strainer and was looking for robust. The Johnson (at least in the picture) looks pretty good. As far as my manual diaphragm
pump, I have a Bosworth Guzzler 500, which has worked intermittently the entire trip down to Mx. I'm trying to splash and I'll be damned if I'm going in without a way to remove water
. So I took the manual apart today and lo and behold, both diaphragms were in backwards! The fabric
side of the check flapper was to the seat. The rubber seal size was pointing away from the flow. I switched them around and it works great!
