Yesterday my son went to the dealer to get a part for a 85 vette and was told that there was a new service bulletin out on ethonol.
The GM fuel pumps are now made to be compatible with ethonol because of the problems they were having.
I didn't get much as I was not there but the parts guy said some pumps were only lasting 6 Mos.
It was advised not to use any after market pumps as they are not compatible.
I wouldn't think this is what a dealer had to do to sell pumps.
Maybe Tom can tell us if he got a bulletin?
