Resolution:
I want to thank everyone who replied with such valuable information.
The reason I went to the Ford Dealership is becaused I did some grunt work trying to find a shop with a lift that could go high enough and was long enough for the 27 ft RV. (in this little area) My regular mechanic could not accomodate nor could anyone he trusted. I checked with Ford and our RV dealership as well. While Ford wasn't cheap, it was less expensive of the 2.
In addition to this forum, I checked with my mechanic and he put me on to his parts guy. He asked for these specifics:
Production Date - is 11/19/90
Motorcraft Part # - f1uz9h307aa
36 or 40 Gal Tank - 40
Mid chassis or after axel - after axel
The closest he could come was June of 1990 and f1uz9h307ba
Ford called me today and the part works and the RV runs fine.
However, now that I have read all the posts, I need to make sure the gas gauge works.
I hope this information helps anyone else with this problem.
Thanks
Dave
