Well I’m back again...discovered I was having ground problems but now gauge reads full with key off and moves to empty or near empty when key is on...works fine with sender outside the tank..this a 12v conversion with a new 12 v gauge and 30 ohm sending unit. I have the sender grounded to negative post of battery. Don’t mind not against carrying gas can but Mema won’t ride with me since the only 2 times she rode with me we ran out of gas!😜😜😜
