The water pump on my 1983 F-250, with 6.9 diesel, needs to be
replaced.
There are several brands of pumps available.
Most likely will opt for a new pump instead of a rebuilt.
I am trying to decide on which brand of pump to purchase.  Prices are
all over the map.  Cardone, Airtex, Motorcraft and others are
available.  Quality and price are important.
