there was a recall on these fuel pumps, the owner i bought my 90 from didnt take care and at 110,000 miles they both went. i replaced both of them but made the mistake of not replacing the regulator, about 5 or 6 thousand miles it failed. i should of known because in the recall they replaced the fuel pumps and the regulator, they didnt say there was anything wrong with the regulator but it was part of the replacement. im guessing that the new pumps caused problems with the regulator, anyways after the regulator was replaced everything worked great. i bought my new pumps on ebay, $186.00 for both to my door, that was over 50,000 miles ago and there still working.
