Gas Guage
I installed a new fuel tank sending unit on my gas tank and hooked up the gas guage to it. But for some reason if I let the truck sit over night in the morning the gas guage reads empty but if I use it in the evening again the gas guage reads were it's suppose to be(it works). Can Someone help or tell me what is the problem. I have a 1969 GMC C25 I would also like to know what is the correct way (step by Step) on how to connect the fuel tank sending unit to back of dash
