Wires to gas gauge

Since I forgot to label the pink and red wire on my fuel gauge when I started this chore/ adventure, as you hold the gauge in your hand face down, the red wire gets attached to what side? Left or right.TIA

Ok at the tank I have a 3 to 5 volt pulse with the wire on the stud. Good or bad? And now it gets better. Removed the sender from the tank, connected the ohm meter and with the float likes its in the tank and in the empty position [ down by the sock?] I have 0 ohms. The approx half full position indicated 0 ohms and the full position read approx 25 ohms. My guess is I'm due for a new sending unit. Good guess of not?

Is it better to try Advance and other box stores or go to the catalogs? I need to finish this fun.

I don't know who is better.

Who makes the better fuel level sensor? Crown, Omix someone else?

I think there was a question about this not to long ago. Use search I guess.

my new sender arrived today. A little tweaking and my readings are 70 empty 26 at half and 14 full. Is that close enough?

Got everything all together again. Put some gas in the tank, charged the battery after using the cd player while working on it. Fired it up. All good. Grab a celebratory beverage from the fridge.Take a healthy pull and walk back to jeep.Much to my suprise the gas gauge DOESN'T WORK. I'm about ready to lose my mind. Any ideas as I have no clue now.Help

Drink another beer...

Any way, did the gas gauge work until you got the drink?

Also, run the same test over again.

I installed a new sensor and the ground popped off. it then overheated the wiring on the fuel level sensor and now my gauge is a little 'erratic' when it hits a certain spot.

an ohm meter will help . check the resistance from the sending unit again.

Like the title from the old tv show 8 might be plenty. Thought about it at work today, having a 'glass body, would it be a good idea to have a separate ground wire on the dash panel? Maybe I'll run a wire anyway after all it won't hurt will it? If not that means I get to drop the tank again. An old factory saying is coming to my head now. "We do it nice we do it twice" Thoughts?

After a separate ground wire from the tank to the cross member[ flapwheeled to bare metal] and secured tightly still not reading.Further inspection of the wires to the gauge revealed to me that the pink and red wire got put on the wrong terminals. Doing that with a dim light [cause thats all i had]in the drop light. Tonight i used a led flashlight and made this awesome discovery. What kind of ultra fantastic damage have I done now? Quickly approaching the screwit mode.
