I also have one between the pump and carburetor. I need to change the filter that is between the tank and the pump.
Do I need to disconnect the line at the sending unit? Or can I equalize the pressure by just taking off the gas cap so the gas isn't sucked down into the line? Not sure how to proceed. Best case scenario I would only want to drain the gas that is already in the line. I have this fear of having jugs of gas all over the garage.
Thanks for your help.

I take or loosen the gas cap first.
Your PO had it right.
