I am in need of a vacuum diagram for an 88.5.8. I have a chiltons manual and it has 87, then jumps to 90. I was running down vacuum lines earlier and there is a lot more on my truck then on the 87 or the 90. Does anyone have one that they can post for me or know where I can get one?

 

do you have a diagram on a sticker mounted on the inside of your hood? or in the engine compartment somewhere? that is where mine is.

 

unfortunately no I dont, I have found them on here for a lot of trucks but still not the one I am looking for.

 

There are VECI labels at motorcraft.com under the technical resources tab. Then click on quick guides on the selections on the left then the VECI button is at the bottom to your left. You will need to know your trucks calibration settings. I don't know what those are. 88 Ford trucks are there though.

 

what is it you mean by calibrations? Where do I find these?

 

The calibration number should be on your drivers post.

 

got it thanks
