摘要： A fuel filter assembly employs a base which mounts a disposable filter element cartridge and includes a sump for collecting water removed from the filtering unit. The cartridge includes a dual stage filter system wherein fuel flows axially to an upper filter element for removing particulate matter and coalescing water droplets and axially to a secondary filter stage which functions as a water barrier. The filtered fule flows axially downwardly and through an outlet passage from the base. The water collected in the sump is removed through a drain cock.

摘要： A fuel injection nozzle 10 having a nozzle body 12 to which is attached a banjo-type inlet stud 16, by means of heat shrinking. After the shrink fit attachment, a blind passage 20, 22 in the delivery tube portion 134 of the inlet is drilled through to penetrate the nozzle body and form a leak-tight fuel delivery path. A locating plate 106 is supported by a bore 96 in the cylinder head 80 adjacent the nozzle and orients the nozzle into a preselected orientation. In one nozzle embodiment 70, the tip 76 is sealed against the cylinder head socket 84 by a frustoconical copper annular seal member 82 that is preferentially loaded toward the inner seal diameter. The nozzle cap 14 forms a spring chamber in which a spring subassembly 42 including upper and lower spring seats 48, 46, a spring 44, and stem 186 and pedestal 84 piloting the spring, cooperate to permit independent setting of the valve lift off stop limit F and the spring preload B. The components internal to the nozzle body are all insertable serially, without the need for rotation or other complex fabrication steps. A nozzle removal tool 250 adapted for use with the nozzle includes a yoke member 258 for engaging a shoulder 268 on the nozzle and a jackscrew 254 and jacking bolt 252 arrangement concentric with each other, for lifting the nozzle from its socket in the cylinder head.
