follows: First, hand tighten all nuts. Then tighten one
nut to a snug fit. Next, tighten the one opposite to a
snug fit. Proceed, tightening the others in opposite
pairs to a snug fit. Recheck all nuts in same opposite
patterns to be sure they are evenly tightened and you
have a good seal. DO NOT overtighten, as you may
twist the studs off the tank. With a torque wrench,
tighten to 85 inch pounds.
