When I fill the tank with gas it reads 3/4 and goes to E very fast and I still have gas in the tank. So I took the sending unit out and moved the float to full and the gauge goes to 3/4. I also grounded the wire to the gauge by using a battery and the gauge stayed on E but when I grounded it with a body ground the gauge when past F. So I dont know if I need a gauge or a sending unit? Let me know if you need for info.
Thanks for the help.
