i have a 95 6.5 3500 wrecker and i pulled the motor out a few years ago and finally putting one back from a 1/2 ton truck. does anyone know what connects to the vaccum pump.
i know one goes to the tubo, so what else gets vaccum. the truck has a hydro boost system, so no vaccum need there.
thanks for the help.

 

are you running S intake or F intake if F all you have is wastegate if it S wastegate and EGR

 

hey Crazy
it was a S intake on the half ton truck but changed it to the F intake on the one ton truck. there is a sensor on the fire wall that looks like a map sensor. does that take a vaccum hose or is it just a spout for ventilation?
thanks for the response

 

hope this helps

 

crazy
yea thats the diagram for the s intake which was on the 1/2 ton truck i took the motor out of. i did swap it for the F intake so i am covered wastgate only then.
thanks for the help
