Usually these Chevrolets have an electric fuel pump which is located inside the gas tank. I don't think a 1988 has a mechanical pump. You have to remove the gas tank to do this job. vbd

Yes, if the car donating the column commes from a similar GM Corp. vehicle, e.g. 1978 to 1988 Pontiac Parisienne to Chevrolet Caprice or Impala. Change the ignition key cylinder from the Chevy to the donated column, and you are in business, since the chassis are identical. This includes Olds Delta 88, and Caddy Seville.
