Fuel pump; fuel gauge; speedometer/tac
 
I'm changing the fuel pump sometime this week or next because it started cutting out a little bit. While I'm at it, I want to fix the issue of the improper reading of my fuel gauge.

The previous owner swapped a ten gallon tank with a 20 gal and the gauge reads 3/4 when it only has about two or three gallons left. How can I resolve this issue?

Also, my speedometer is not reading but the wires are still connected to the tcase. I heard I need a fuse for that. But how do I get the tac working again??

you need a new sending unit for the tank, there all 20 gallons since the 15 gallon sending unit is no longer made.

if it still reads wrong you might want to try cleaning the contacts on the back of the gauge.
