I'm updating the this pump issue. It seems that the activator assembly is flakey. It only works when I press firmly on the inner connection on the upper assembly. The wire connection is fine. The issue is inside the plastic housing to which the wires connect.
I haven't been able to locate the part itself as an end user. I don't see any salvage yards nearby.
I can get a new replacement from
Scamp for $69 plus shipping, which is less than local camper dealer would charge.
I'll post two pictures. The pump with its description plate and the end where the two red wires connect. The connection closest to the pump is flakey.
