The current Delphi Fuel Pump catalog shows FG053 superceded to FG0270. This is incorrect.

GM truck application.
FG-53 was listed as 1999-2001.
FG0270 listed as 2002-2003
FG053 will superced FG0270. Application is GM trucks 1999-2003

The paper catalog can't be fixed, but the Activant ecatalog should be corrected pretty quickly.
