I got my pgmfi upgrade in the mail today. (Manifold, fuel rail, injectors, etc.). I was wondering if anyone had CLOSE pictures of their 88-91 CRX intake manifold, so that I can find out what hoses I am missing and where to connect them. The auto shop manual vacuum diagrams are kinda confusing, so if soemone could either post pics, send them to [email protected], or explain those diagrams, I'd really appreciate it. Thanks.

here are some pix of my intake manifold. The red circles show what connections i need to kno. I'm not sure which are coolant lines, which are vacuum lines, and what connects where. I read through the service manual, but I just wanna double check with someone who's done this before.

the top one is an vacuum line it leads to the black pot on the richte side of youre car. It's next to the fuell filter
the middel one is an coolant line
the lower one i'm not sure but i think it's a coolant line
pic #2
same as above
pic #3
left = vacuum line
midel = oil out i belive it runs to a black pot on the back of youre engine. It's called a catch can i belive. and it's on the good place
right= vacuum and it runs to ure pressure regulator ( see pic #5 it goes on the top)
most right = vacuum and runs to youre head break cillinder
pic #4
it's a fuell line it coms from youre fuell filter
pic #5
top = see pic #3 right
lower = fuell return line
pic #6
already spoken
pic #7
middel left = vacuum and runs to youre map sensor
top left = don't know can't see it good but i think we already had that one
top right = vacuum but u don't have to use this one if u don't want to
lower 3 cicels = coolant
pic #8
top = vacuum spoken in pic #3 most right
lower = oil spoken in pic #3 middel. It's not a high pressure line. It contains air with oil in it and the catch can filters the oil out of the air
hope this will help u. If the worda arn't corectley spelled sorry but i'm from Holland. I can speak it very wel but my writng is bad as u can see
