fuel tank fuel gauge problem

i know that there are alot of threads on here that explain different tips on how to diagnose a faulty fuel system gauge and sending unit. Im am printing out the article now, and going to go check it. If i am correct all sending units for gm are 0-90 ohm and it shouldnt make a difference if it is a camaro part on a nova or not. Here is what i did. I replaced my fuel tank with a new tank on my 73 nova, however they do not list a fuel sending unit and line set for the car, everywhere i called did not have it, however the same fuel tank is used in the 76 camaro, so i purchased a 76 camaro sending unit and lineset to install in the tank, i measured it before i put it in and it is the same depth and everything. my question is would this combination cause any problems? with a empty tank it reads full, and if add fuel it does nothing, i am going to go run a ohm meter over it all and ill let you know the outcome.

Re: fuel tank fuel gauge problem

your gauge will read full when presented with exactly 90 ohms resistance to ground on the sending unit line.
More resistance will cause it to read "over" full. A full open will wrap the needle clockwise as far as it is physically able to go. Zero ohms will read empty.

If you are reading exactly full with no gas in the tank, I hope the tanks not installed, cause it'll be coming back out.

Perhaps do some of the tests described in the article on the wiring at the connector in the trunk.

I cannot think of any wiring or grounding problem that would make it read exactly full.
The combination of parts you described sounds like it should work.

Re: fuel tank fuel gauge problem

i checked everything out as best as i think i could, i cut open the plug that connects on the tank and i found that the fitting on the end of the wire must have broken off and was getting no conection, it must have broke off on the old tank and i didnt notice, however i connected a aligator clip to the prong on the tank and to the wire and turned the key forward and presto, it went to zero, so im gonna hook it up with a new end and put the tank back on , add some gas and see what it does. hopefully it was just a bad end and will make a simple fix.
