OK, for any that have the same problem. I had two different problems and I was bumping heads with myself.
Evey thing I did, didn't help and I was unable to trouble shoot the real problem.
I decided to go back to basics and replace the sending unit in the tank. I ordered the wrong unit. So, if you are going to replace the sending unit and the pump as a unit, make sure which one you need. This cost me a day's work.
I listened to the people with similar problems and removed the bed. That was a piece of cake as was replacing the complete unit.
Then I went to the circuit boards (For the gas gauge) that I had picked up at the local junkyard and on eBay. The original one was bad and I didn't know which ones were good until i fixed the sending unit in the tank. It turned out that all but one was bad.
Here again, you guys were right. The float had a leak and filled with gas and of course, sunk to the bottom.
I still replaced the whole unit since i didn't want to do this job anytime soon.
Now, that I know everything works in the fuel gauge system, I will go on to fix the water temperature as soon as I find the sensor. One person has said he thinks it is on the driver's side of the block below the oil sending unit. That is a place to start.
I would still like to know if I can replace my gauges with one that has a tachometer. Any feed back on this will be appreciated. This 74 year old man is feeling pretty proud of himself right now.
