This TSB article is being published to consolidate three previous TSB articles on slow fill rate.
ISSUE:
Some trucks may experience a slow fuel fill rate. This happens because the current fill pipe does not handle large nozzles and high flow rates
usually available at larger fuel stations and truck stops.
ACTION:
Install a new fuel fill pipe. The new fuel filler pipe has the following features:
^
No fuel restricter plate
^
A raised inner funnel
^
A larger diameter inner hose.
Refer to the appropriate model year F-Series Light Truck Shop Manual, Section 25-50 for service details.
NOTE: EACH CHASSIS CAB MUST HAVE A NEW FUEL FILL PIPE AND FUEL FILL HOSE ASSEMBLY FOR EACH TANK. BEFORE
ORDERING PART, DETERMINE WHETHER THE AFT OF AXLE TANK IS STEEL OR PLASTIC. THE FUEL FILL HOSE ASSEMBLY
IS DIFFERENT FOR EACH TANK. THE FUEL FILL PIPE IS THE SAME FOR ALL TANKS.
