At the risk of sounding like a wise guy I don't think I have ever seen a torque spec for the cover nuts. I coat the gasket as one does not want air leaks in the tower and I "snug" the nuts down but not super tight. Don't overdo the coating as cleanliness is next to Godliness when working with the fuel system. I'm one of those that think a little gooey is always good on the gasket. Too much torque may also warp the cover. Check the cover to make sure it is flat.

Thanks for the advice D4Jim. We torqued the nuts evenly to 35Ft Lbs. No leaks.

aaaaaaah!!!! Dozerman, Sounds like you did er right! That is good info so will keep that torque number on file. Unfortunately I have too much of the "shade tree" mechanic in me and I never reach for the torque wrench unless its over 75 ft lbs. As a kid in the '60's I don't remember having a torque wrench on the farm but head bolts and lug nuts had to be "darned tight".

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
