After market Fuel Level Gauge?? Ok I have a 1981 TTA, with a 2001 Silverrado harness&PCM, but my fuel assembly in the tank is out of a 96Trans AM. What in dash after market fuel level gauge will work and read correctly? The stock gauge is in there now, but don't read correctly.

Well, mine is not hooked up yet, so I can't tell you how easy it works (or even if it works at all), but I bought Speedhut gauges, and the fuel gauge has a little wire you can plug in with a button on it. You can hook it up to your stock sending unit in the tank, and there's a procedure to press the button at full, and at half, and at 1/4 (again, I don't understand this fully as I have not done it yet). This somehow magically teaches your gauge to read the stock sending unit.

There was an article on thirdgen.org on how to switch the resistors to make a different sender work with a specific gauge.....not sure if it really works..
http://www.thirdgen.org/techboard/lt...-ls1-fuel.html
What you have in your 1981 is 0-90 ohms (dash gauge end)....0 is empty...as the float floats up....it increases to a max of 90ohm. GM changed the 0-90 ohm right around 1996-1997. Your fuel tank sender may be a 240-40 ohm... It won't work with the incorrect dash gauge.
Autometer sells some gauges that are programable. I chose to retain my 0-90 rather than re-buy the programable or ohm specific one. It all depends on what gauge series you want to go with....Good Luck,

Autometer makes several gauges that are fully programmable...sport comp 2 series is what I use
if you find out what the fuel sender is supposed to be empty and full from a google search, or find one at a local parts store that you can test, you can buy resistors and program the gauge without having to pull the pump....
or you can pull the pump, hook it up, set it empty, set it full and program the gauge without having to measure the resistance.
or you empty the tank...turn key on, hit the set button, fill the tank hit the set button again...then you can kill the key and its set....
all of their programmable gauges have ranges that are presets as well. 0-90 ohms is a good example used by many manufacturers...but only "some" of the programmable ones will allow you to set it to any value, so you have to doubel check that it has that mode before you buy it.....like I said.. I know the Sport Comp 2 series will do it because that is what I use.
