I have an 84 Seville
The gauge was on 3 gallons on the highway and then the car died (out of gas), Do these things get stuck and what would you suggest checking. I appreciate any help I can get you guys are great.

 

Pull the tank and replace sending unit and if you are in there anyway do the pump at the same time.............

 

You have 2 choices, get gas before 3 gallons shows or drop the tank and replace the sender. Sometimes the rubber hose joining the pump to the sender can get a pin hole and suck air when fuel is low, so ck the hoses connecting the pump. Replace pump? hard call, mine is as old as yours and assuming fuel filter gets changed every 5 years or so, and it never runs out of gas, it will go a long, long time. Running out of gas is the most common cause of pump failure. The fuel lubricates the pump, keeping it cool. Out of gas, pump on, it burns up.

 

I appreciate the feedback,
Im keeping gas in her, Do you guys know where would be a good place to order parts for the 84 s????
