Torino 15 #1 Posted March 2, 2014 I am cleaning out my gas tank on the 520. The gas gauge works but I was wondering if it is anything I should do to the sending unit while I have the tank off of the tractor? Share this post Link to post Share on other sites
chazm 413 #2 Posted March 2, 2014 If its an in-tank sender, just check to see of any signs of leaking, if so you may need to reseal it Share this post Link to post Share on other sites
Save Old Iron 1,571 #3 Posted March 2, 2014 (edited) definetly remove the sender from the tank during the cleaning if not then recheck the sender with an ohm meter to see if the resistive element in the sender still responds to the float movement. check the demystification guide for expectations on full and empty ohm values. check for dead spots in the readings as you raise and lower the float. the readings should change smoothly to make these mesurements, attach one ohm meter wire to the mounting plate and the other to the wire terminal on top of the plate.
