1981 e250 vacuum diagram
im new here but looking to start working on my 81 e250 with a bone stock (full emissions which i dont need or want) 351w. i tried searching with no luck for exactly what i need but i was hoping to find a vacuum diagram so I can start chasing a vacuum leak and eliminating emissions and all the unnecessary items like cruise control. planning to do a dual plan 4 barrel swap and 600 holley soon as well. thanks!
