wow...

try this

there are 5 or 6 different variations just on the 5.0 in 1990... and i did not print them all up to compare..

there is a white sticker about an inch wide and 3 inches tall.. with a series of numbers on it..

can you copy them and post them as they are..

90 R10
3f 24
1Q 12..

something like that.. it shows us which vacuum diagram to use... which emission set up you have if there is any difference..

here are some various years of 5.0 intake manifolds i am not saying that this fits yours... just to let you know...

nope... not the belt diagram

this will be on a valve cover usually....

its the emission calibration..


see the cryptic numbers at the right side of this 79 label.. thats what is needed..

you might be able to spot the proper diagram out of the 5 or 6 if you print them out.

DOH!!!

print the 5 or 6 different emission labels linked... see if you can figure out by what components are there which one it is????

i can even help if you can narrow down which one it is... as i understand ford vacuum diagrams and systems...

is there anything left of the factory emissions label...
there is a calibration number that would match the ones at AZ site i linked...

i know what you are going thru...  i work on a lot of early 80s fords with carbs... some computer some not... in 1981 there were DOZENS of vacuum diagrams for the same motors...
