I had to remove the engine during a manual transmission kit installation. I wish I had photographed the vacuum line routing. I'm running rich which leads me to believe that I have not routed the vacuum lines for the fuel regulators correctly.

Can anyone with a 1989-1991 with Marelli Ignition send a few photos of how your vacuum lines are routed, please?

Any other thoughts on running rich?

Photos can be emailed to thebakers@centurytel.net

i'm wondering if you put in the kiesler 5sp
tranny. just curious, and wondering that if you did is it that great in terms of performance and
economy? the kiesler manual has gotten some exc.
yes running rich could be a vacuum problem, if not connected as original.
while i dont have the marelli ignition on my xjs, i think i have the routing of vacuum lines for your xjs in my xjs factory repair manual as well. i can check and email you copys of the pages. let me know if that would help before i scan them and email.
