I cannot locate any repair/service data for these parts in the Army TM's. They are very poorly illustrated in the IPLs. I am working on a 1960's UH-1H with these crashworthy fittings. In particular at this point a leaky lower feed fitting at the bottom of the right rear fuel cell. It is item 11 in TM 55-1520-210-23P-2 (Chg 16) figure 328 page 1360. Can anyone point me towards more detailed guidance on removal and repair of this coupling? PN 205-062-653-1
