  • Lycoming fuel injector servicing

    I need a reality check, please, nothing to do with Taylorcraft or Continentals or little Lycomings. Hence the post here in Rants & Raves. (It's neither a rant or a rave, just asking opinion from experienced folk here).

    I'm servicing a bog-standard fuel-injected Lycoming engine. It has injectors like the attached photo.

    I also attach two pictures of the September 2008 Lycoming Service Instruction (SI) on injectors.

    Figure 2 (see attachment) apparently shows the common injector for a lot of Lycoming engines.

    Step 6 (see attachment) , it talks about how to orient the injector.

    My injectors have never looked like the 2008 SI, and this is a 1984 engine. Mine have a shroud and a gauze.


    Am I missing something?

    Others please chime in too, but I'm pretty sure the drawing is of an older style nozzle. The injectors you have should not have any particular orientation.
