THIS BULLETIN APPLIES TO THE U.S. AND CANADA; AND SUPERCEDES P20 SB 23-132 ISSUED MAY 1986.
NOTE: New information is highlighted in the margin.
Foam formation in the fuel tank can affect fuel supply causing fuel pump noise and, in extreme cases, hesitation and lack of power. Vehicles
operated in areas of high ambient temperature and/or high altitude are more subject to this condition.
To improve fuel supply, a new pre-pump with higher fuel delivery capacity is now available.
