QUOTE(McMark @ Apr 16 2018, 01:19 PM)  The problem there is that the 1.7 an 2.0 runners have the fittings at different angles. So any angle I build in will make two versions necessary. (IMG:style_emoticons/default/pinch.gif) Ah, poop. No good compromise angle that will work OK with either, then? That's a bummer. --DD |

Why not build a fuel rail with proper openings for the injectors to fit into and seal as designed?
The rail could have brackets that attach to the studs on the intake runners and hose connections on each end. It would not look stock but would clean up the engine compartment and eliminate the injector elbow hoses. That is the plan I have for the megasquirt engine in the garage. Jim |

Yes I was thinking of something like that.
But I like the smaller injectors Mark found and I think with them a bit lower profile rail could be mounted. Jim |

Have you changed the lower orings on the injectors?
They look different to the standard round oring that is normally fitted to these style injectors. I assume you are fitting original style square rings? Cheers |

QUOTE(jcd914 @ Apr 19 2018, 11:08 PM) Why not build a fuel rail with proper openings for the injectors to fit into and seal as designed? I looked at it, but machining costs were just as high and I don't like the way it looks. These brackets hold the injectors FIRMLY. I will still be doing pressure testing for possible leaks, but my initial impression of them mounted is that a fuel rail wouldn't add anything for rigidity.QUOTE(edwin @ Apr 23 2018, 10:17 AM) Have you changed the lower orings on the injectors? Yup. I cut off the round oring and the plastic support, then the stock square o-ring fits perfectly. Lucky accident.They look different to the standard round oring that is normally fitted to these style injectors. I assume you are fitting original style square rings? Cheers |

QUOTE(rdauenhauer @ Apr 19 2018, 11:40 PM) Will the engine go back in with those rails? With straight hoses the existing rails hit the engine shelf. These will not bend out of the way. |

I always remove my fuel rails (at least now), as it's easy to damage the hose on the injectors.

(IMG:style_emoticons/default/agree.gif) Mike's got it. Pulling the injectors off the intake is the best way to be safe.
But, no, these wouldn't clear the suspension ears. |
