    I'm going to be pulling my '71 GS gas tank soon to replace the gas gauge sender. Regarding the wire from the sender that feeds the dash gauge: Can I tilt the tank down during removal, and unhook this feed wire from the tank sending unit with my hand....OR, do I have to unplug this gauge feed wire at the connector in the trunk prior to beginning the tank drop, and remove the entire feed wire with the tank, before being able to unhook the wire from the sender?

    Second question, please: I have the factory N-25 bumper exit tailpipes on the car. It looks like I DON'T have to remove them from the stock mufflers in order to give the tank room to drop down. Could someone please confirm that this is correct?

    Thank you very much for any help, Gang. John in Wisconsin

    Disconnect the tan wire from the trunk. Once the tank is down and out, you can remove the wire. The tank should have just enough room to pass in between the pipes. You shouldn't have to mess with the exhaust at all. Make sure you run the tank to almost empty. Gas weighs 7 lbs or so per gallon, so a few gallons adds a lot of weight. Plus it sloshes around which is a problem if your trying to balance it on a floor jack
