PREFORMED PACKINGS, SATURATED
When preformed packings are saturated with fuel or oil for an extended period of time they will expand or swell.
In most
cases it is nearly impossible to install a used preformed packing in the same place it was removed.
If a preformed packing
is cut or pinched, it should not be reused.
Limitations:
Lines may leak at a reduced rate.
Personnel/Time Required:
•
1 soldier
•
Time determined by location and amount of damage.
Materials/Tools:
Used preformed packing (scavenge from available source) or packing, preformed (item 45, Appendix C)

following procedure if packing is not damaged or cut.
1.
Inspect preformed packing when removed from fuel system.
2.
Remove as much fuel as possible from preformed packing with clean rag.
3.
