Are the gas tanks the same in the '90 hatch and '90 convertible? Got a dead gas gauge in my 'vert and access to a hatch for parts, and thinking that a tank swap would be simplest (and best since the hatch tank has a 190 Walbro in it too!). Am I right that dropping the tank is about as complicated as pulling the cluster to test what's wrong, and that the sender is the more likely culprit? Or would I be better off pulling the gauge cluster first to test for sender voltage?
