I really hate those aftermarket tanks. Be sure to pressure test and make
sure the carbon canister is clear and that the valve near the air filter is
working. I have seen these tanks both expand like balloons and also collapse
from fuel pump suction when the carbon canister fails.

Thanks Dennis - The new sender I installed didn't seat properly on the new
gas tank (it felt and looked good at the install). The metal on the tank cut
into the plastic tabs on the sender in two places, rather than getting
"pulled" into place correctly. Looks like a bad combo of new parts - thinner
metal on a new gas tank, coupled with softer plastic on a new fuel gauge
sender. I installed my old sender with a new o-ring - will see if that does
the trick.
