Asked by May 24, 2017 at 12:13 PM about the 1969 Cadillac DeVille

Question type: Maintenance & Repair

I have a 69 coupe deville and I ran it on empty for
the first time and put gas in it and it started running
terrible. The car felt like the tranny went out or the
gas was extra bad. It barely made it home and it
was only going maybe 10 or 15 mph at the time
while I'm flooring it. My needle valve on my
carburetor was down so I took it and got it cleaned,
because it had already been rebuilt. After that I put
the carburetor back on and cranked the car and it
ran but still sounding and running horrible. I never
tried driving it after that but I'm curious to what I
should do next or to look for... I know I need a new
tank, but while the car is running you can just hear
air sucking from the carburetor what's making it do

Most likely some crud got through the filter and wound up inside some jets inside the carb, unfortunately it will take another tanking to get it all out.

Thanks that's what im gonna replace first that way I can at least have fresh gas going thru the car.


sucking air is what the carb. does , a car that old you must face up to the un-face up to able and drop the tank , electric in line pump is always an easy option
