Just went through a Evinrude “Junior” tank and noticed a couple of
things that made me go hmmmmm?
This original diaphragm (or at least the one that was in the tank)
has an extra hole in it, that lines up with a dome with a hole.
The new diaphragm I have does not have this hole.
Just curious as to what’s the deal with that?
Regardless, the primer works great with the old diaphragm.
This cap had no chain nor slot in the washer to attach one.
Were the Junior tanks like that, or someone switched out
the washer and eliminated the chain?
Hey Buc, I’ve never seen an extra hole that you’re referring to in the diaphragms. The only extra hole is in the earlier diaphragms for tanks that had the aluminum push rod like that tank, and not the black plastic button. And the Junior tanks did originally have slots and chains just like the 6 gal.
