Hi all,
Quick sanity check on injector install. I just installed a set of Standard Motor Products FJ67 injectors on my 2.0 D-Jet with brand new seals at the intake runners. What surprised me: * No “click” when inserting them * Only the tip went in * Final seating seemed to happen when tightening the retaining clamp They’re now sitting straight and look properly aligned, but I’m not fully confident they seated by hand before the clamp pulled them in. I can also still see a bit of the rubber seal sticking out at the base (see picture). I’ve only done one side so far, still need to do the passenger side, so I haven’t been able to run the engine and test for leaks yet. Is this normal with new seals on these cars? Should they fully seat by hand before the clamp goes on? Any risk of vacuum leaks if the clamp did part of the seating? For context, seals were installed dry. Thanks y’all   |

Looks correct, the rubber is an insulator so the gap is fine. The larger o-ring when placed correctly it puts the pressure on the port to prevent an air leak.
In this case only the tip goes in. |

Thanks y’all i just installed mine as well, and noticed that the nose is shorter than the OEM ones, but tip width is the same and with new seals i found i have a good tight seal wwhen the retainer is tightened down. |

Thanks guys! There’s always that percentage of “I absolutely don’t know what I’m doing” in the back of my mind (IMG:style_emoticons/default/aktion035.gif)
