ok then...no replies on my previous post (I thought I would append an old similar post rather than open a new one).
The valves look clean and seem to operate as designed. The o-rings and plastic washer look ok as well.
Do they wear out such that a visual inspection is worthless?
I can't find the source of the leak but I suspect there is a gasket between the pump and the rear-end. The "L tube" is snugged tight.
It's a 1250 with a 2050063 SN and I think was one of the first in the QL series.
