Fuel Sending Unit Question

You shouldn't have a problem. Clean the general area before taking anything apart. Dont use pliers to try and adjust the keeper to tank spacing. That could alter the tanks sealing surface as cause a problem. Hold the sender and seal in place with one hand and start the locking engagement with the other. Get it as tight as you can by hand. Use gloves. Cuts with gas in them are no fun. Use brass pecker to rotate lock ring fully against the stops. Happy moparing.
