Problem solved!
Moodymike you'r the saver of the day...I put my Pela to the engine pump line and got a river of diesel to the filters and even the bad black button pump started to work again!
Engine running...Winterizing done...ALL is well
And I even learned a new trick today...
In 8 years of ownership I never had this problem ,I wonder why now?
Anyway many thanks to ALL of you!
This forum is a joy!
