Need to drain gas from the gas tanks on 2002 C5 getting old, I do not want
to run it out and put the mileage on the car I plan on refilling it but
treating it first with sta-bil. After refilling with fresh gas (93 oct) I
will run it a little to get the fresh fuel all the way to the injector.
At this time I have removed the flexible fuel line that runs from the fire
wall to the injector rails and put a electronic fuel pump there to start the
process put it stopped pulling fuel and there is about ½ tank left in the
Thanks for your help.
