I love the smell of diesel in the morning
As a side note, I bought the 1 13/16" socket from Sears...IMO not worth a special tool nor shipping costs...it was a tight clearance but it worked...the same size fits my fuel guage sending unit as well...might as well clean that puppy too if you're really hunting for goo....
Search the threads on the sending unit, if you're tank strainer is fudged up, the sending unit will be too.
Cheap fix and you can use the clothes you wear to start your next fire to grill up lunch!
