Gas gauge woes..

I replaced my old tank, sending unit, fuel line, and rubber hoses. Then I put my new tank and new sending unit in, also put in 5 gallons of gas. It didn't even register until I put in another 5 gallons. Weird... but after the initial past half tank it now works fine, Full to Empty, it even reads pretty close. Might be like mine was and need more gas in the tank to get it off the bottom.. I kinda think sending units have a sticking point when almost down to the limit of showing empty. But I did check it with an Ohm meter before the install and knew it was fine. So it only left the fact of a bad ground or bad connection at the tank. I had my guages tested and repaired before I changed the tank.. maybe this will help a little..
