trying to remove old pump,not sure what to do after disconnecting lines
fuel pump on 1998 Oldsmobile Intrigue
Clean the area where the fuel pump cover is attached to the fuel tank. With a BRASS drift or punch, not a STEEL drift or punch, tap the locking ring loose. The BRASS or punch drift is to prevent sparks so you don't start a FIRE!!
Get a repair manual if you intend on doing your own work.
