Wink - I'm glad you joined.
But you may have missed the email that Scott sent you asking you to go to the New Members Start Here folder and start a new thread/topic there to introduce yourself. One of the reasons we ask that is because the guidelines are posted there and we want to ensure you've had a chance to read them as we hold everyone to them. So, have you?
As for the sending unit, go to the page at Documentation/Fuel Systems/Fuel System Part #'s/Fuel Senders & Pumps. There you'll see the various tanks and the sender part numbers to go into them.
