Today the new accumulator came,I readied my tools and placed the old 420 on the lift,after playing with the stubborn fuel line and finally broke the slip nut from the line it came off.next that dang screw got its turn with the cut off wheel of my dramel,The new was ready to be put in place,No leek all was well,first thing I noticed was the fuel pumps got quieter not sounding like they where running there heart out to keep fuel in the system,this must be a plus,maybe they will last longer! The engine starts now when warmed,still a little shutter on start but not like it was.Miss Debbie and I took a nice ride in the country stopped to eat,Friday fish, and not one sign of trouble,restart was instant and pretty smooth. Hope this helps the next person with similar troubles.JNT
