has anybbody had any problems with there sending unit mesing up?

i cant get my gauge to work for the life of me.....tried everything....

one guy said that the sending unit will read 0ohms empty and 90 full
mine is pegged at 116 ohms

do you think its bad ....there is about 1/2 to 3/4 of a tank of gas in my car....i just wished i knew exactally how much ...fuel gauge hasnt worked since i bought the car..

at chevy the fuel sending unit is $685 and yes that is just the sending unit.....what are my options?

Yes it's the sending unit. And Yes Chevy’s prices are way out of line.
I bought one from Autometer but the Resistances didn't match so I used an Autometer Gauge also. I needed to rig it to fit and work in the originals place (not to hard).
If I had known at the time I would have gone this route. Summit sells some after senders at:

It will take some adapting to work with the original tubes and fuel pump assembly.

all i need is the gauge to work im not even running the stock pump... so all need is the sending unit can i get one to bolt in to the stock location?

The only way to do that is to buy it from the dealer. The stock sending unit is integrated into the fuel lines and the only part that was meant to be replaced is the fuel pump itself. If you pull the sending unit out you'll see what I'm talking about.

With some minor fab work you can get one of the ones from Summit to work in the stock location.

can some one get me a part # ..... does anybody have any picts of what it would look like finished.....

I gave you a link to Summit, they have 3 that might work.
Mine was the wrong values and required a new fuel gauge.
The ones at summit will work with the stock gauge.

I don't have a before picture but it looked similar to the after picture. The white piece with the float attached is the sending unit. You will need to remove the original one, drill 2 holes and bolt up the after market one, if it's like the one I got from Autometer.

Here's an after Picture:

just a quick note but year one will rebuild the stock sending unit for $150. My car did not have an intank fuel pump, it was just the sending unit. neither did either of my 84's.. impossible to find a sending unit without the pump attached to it though from a dealer. they want to sell you the whole thing. Although I was quoted a $450 price tag. (non-dealer but still an ac delco part)
