CJ aftermarket imported fuel gauge?? - Pirate4x4.Com : 4x4 and Off-Road Forum

Bought an imported (Omix Ada) speedometer/fuel gauge/temp gauge cluster for my 78 CJ5. Realized that some of the sellers posted warnings about recalibrating the fuel sender. Anybody done this already? Easy ways to get it to work?
Right now with about a half tank of gas it's pegged on full. Add a resistor?

Wanted to add that I already put a new sending unit in the tank and am getting around 37 ohms reading at the pink wire-the input to the fuel gauge. Yet my new gauge is pegged full.
Anyone get instructions with their new speedometer gauge cluster or fuel gauge?
It's a Omix ADA imported setup.

OK I figured it out- for the sake of search function people in the future here's the solution. I was testing my gauges before installing them as I didn't want to waste the install time just to find it wasn't working. I hooked up a test lead for a ground to the speedo housing as it is necessary for the dash lights and fuel gauge to work. When I went back to test this again (at the urging of someone on a different forum) I figured out my test lead wasn't grounding good enough. Now if you are experiencing the same problems with the thing installed already you need to insure the ground to the housing is good if your fuel gauge is pegged like mine was. Hook up a separate ground if necessary. PM me if you need links to more info-peece out!
