New O-ring Seals And Additional Clamps Used In Instrument Panel Fuel Filter Differential Lines Group {1250}
Usage:
3500 Series Engines
Description of Change: New O-ring seals are used on the instrument panel fuel filter differential lines group. The new O-ring seals are more resistant to failure at high operating temperatures. Two sets of clamps have also been added to the group. The clamps help prevent line cracking due to vibration.
Adaptable To: The two new 6V5048 O-ring Seals are a direct replacement for the two former 3J7354 O-ring Seals in the 2W8371 Instrument Panel Fuel Filter Differential Lines Group.
Two 9L8715 Clamps, two 9L8716 Clamps, and two 5P4939 Screw Assemblies have been added to the group as shown in the illustration.
