Re: Vacuum hose routing/ diagram?

Huh, well there's my nice clear diagram for my truck! LOL

So when you say "switch on the firewall" were you referring to the HVAC control hose? It is hooked to the manifold vacuum on the back on the motor.

Have the other nipple on the manifold vacuum going to the hose on the air cleaner.

Have vac advance going straight to carb.

Have EGR blocked off for now (have some caps ordered, should be here in a day or two)

Have front TVS on the thermostat housing looped back into itself for now (will put caps on when the come in)

Left carb to PCV line and line from PCV to canister where it was

Put line from canister to other nipple on front of carb. Canister is plumbed as it was stock with the exception of the purge signal hose, which I now have going straight to the carb.

Anything I'm missing here? It runs ok, but doesn't have the power it did before I starting putting new hoses on, and the big issue is a bucking and missing when I go into third gear (4th if you're considering granny low to be 1st)
