86 4000

[tombin]

Hello, i have an 86 4000 FWD with the 1.8L 8v.  I went to do a fuel
pressure test, and could not locate the warm up regulator.  Should'nt it
have a feed and return fuel line?  THe hayes manual says it does not.

Also, there is a piece in the upper right hand corener with 3 vacuum lines
comming off of it.  what is this?

I have no been able to find a decent website that has a complete breakdown
of the motor, could someone point me to a good website for this info?

Thanks!
