[AT] fuel Fitting identification

[Gene Dotson]

    My Case parts book identifies them as Imperial Brass tube and sleeve 
connectors.

    The clearance seems about right. To assemble them, you insert the rubber 
sleeve in the nut and start the nut on the male fitting. You then insert the 
tube through the rubbe sleeve and snug the nut down (not too tight). This 
compresses the rubber sleeve around the tube for a fuel tight seal. These 
are only used on the low pressure side of the fuel system.

    These sleeves are available from diesel service shops at a much lower 
cost than the manufacturer.
