I did a sender swap in my 56 with a stang tank a while back. What I did was to clamp the stang sender to the bench and magic mark a line along the float path. Then remove the sender from the tube and replace it with the chevy unit. Play with the positioning on the tube and the float arm lenght until you mimic the origional float path. Make sure that the Chevy sender goes to the full limits and that's it. A little solder and a new ground strap and it's over. Good luck Richie Z
