GMW16654 2nd Edition, October 1, 2016 Fuel Filler Pipe Pressure and Vacuum Cycling Durability
More info
Description / Abstract:
Introduction
Note: Nothing in this standard supercedes applicable laws and regulations.
Note: In the event of conflict between the English and domestic language, the English language shall take precedence.
Purpose. To determine the fatigue life of a Fuel Filler Pipe (FFP) Assembly, including attachment points, by alternately applying an internal pressure and vacuum to the FFP at a given rate.
Applicability. All passenger cars and light-duty trucks which have a primary or secondary diesel or gasoline fuel tank of metallic or non-metallic material.
Remarks. This procedure simulates pressure and vacuum variations which develop within vehicle fuel tank systems during vehicle operation. Pressure and vacuum variations occur due to:
• Fuel motion
• Tank wall motion
• Engine vacuum via purge
• Vapor pressure changes due to change in ambient temperatures and vehicle hot fuel handling
This test may also show a tendency of FFP components (e.g., filler hose or vapor bundle) to “oil can” due to the pressure and vacuum extremes of the test.
