While pulling my injectors on my '90 (originals with 220K !) last night for replacement since they have started leaking at the seam ( I finally ordered some Bosch D5B injectors from fiveomotors) I broke the rigid vacuum line from the MAP to the throttle, right at the grommit attaching it to the throttle assy so there is no post left to slip a tube over to couple the two pieces. Anybody have this happen to them? I was thinking of drilling out what's left in the grommit and shoving in the remaining vacuum line with a little help of some RTV. Do you think that'll keep it in place? The "stealer" wants $30 for a new tube assy.
