How to replace the gas meter inside the second tank of my 1995 Ford F350 Pickup.

The fuel sending unit is located inside the gas tank. Loosen the straps and lower the gas tank and unhook all the lines. On the top there should be a big round disk holding the sending unit down use a hammer or dead blow hammer and a punch to knock it counter clockwise. The sending unit should pop up, save the rubber o-ring that is under it as you will reuse it unless the new sending unit one has one. Pull the sending unit out of the tank. I believe on those ones you have to reach into the tank and pinch 2 clips on the sides to get the full unit out of the tank. Reverse order to reinstall. Make sure ring on top is all the way back on before putting tank back in place. I usually get someone to help with the hold down ring and we both use a dead blow and punch from each side to knock it back into place
