Cadillac Seville / Cadillac Eldorado Forum Discussion, 85' Eldorado Biarritz Sending Unit Help in Past Cadillac Vehicle Discussion; I have a 1985 Eldorado Biarritz and i just put a new gas tank on it and my digital fuel ...
I have a 1985 Eldorado Biarritz and i just put a new gas tank on it and my digital fuel gauge doesn't work, so i went to look for a new sending unit and it will cost me about $150 or so. but with everyone i have found it says without digital gauge. Any idea where or how i can find one with the digital? any help would be appreciated.
I got the car from a family friend who had it since 95' and when i bought it, it had been sitting for 11 years with a half-full tank of gas and the inside of the tank was full of rust and the car didnt run so i do not know if it worked before i put the new tank on. this is that is displayed mms_picture (800x600).jpg

Re: 85' Eldorado Biarritz Sending Unit Help
That display shows empty. How much fuel did you add to the tank? If its got more than 3 gallons, its grounded either within the sender or the wiring to it. The harness is in a flat plastic sheath that runs over the tank and plugs into the body harness by the rear bumper. Check for voltage at the plug and report back. That same sender is used on the Seville as well and must be a digital sender. Different ohm readings between the 2 senders.
I put 10 gallons in the tank after we put the tank back on and ill check the wiring. Thank you so much it is really annoying having to carry a 2 gallon gas can in the trunk because i dont know how much i fuel i have left and i dont know how accurate the fuel used gauge is.
Hey did you ever find a sending unit compatible with the digital dash? I just got an 85 Seville with the same exact problem. My mechanic says he can get me the replacement fuel pump no prob, but can't find the correct sending unit anywhere online. Like you said, guessing at my gas level is annoying..
