Note
AllData Editor Note: The manufacturer did not supply a diagnostic flow chart for the Balance Pump System for the dual tank setup for model year 1999 trucks. Using the one from Model year 1998 may be helpful.Be sure and read TSB 01-06-04-037 (click on Technical Service Bulletin under Fuel Delivery and Air Induction). It explains why Transfer Pumps are burning out and what must be done to prevent the replacement pump from also burning out.
