Update: Fuel tank not filling up >>>
Well, the dealer replaced the fuel senders and all seems to be back to normal again. There was a popping sound when the tank used to fill up earlier and that seems to have gone as well ...
Not sure if it was bad senders or whether there was an airlock in there that got cleared when they replaced the senders. Thought I'd share in case some of you have or may face a similar situation in the future ...
Thanks for all that helped with the diagnosis.
