Quick Egr Blockoff Question

[john]

I am unsure of what vaccum lines need to be blocked off and what needs to be reconnected. The line that comes off the canister to the firewall goes to a metal mender which bolts it to the firewall. Is that supposed to be reconnected to a vaccum source or am I just supposed to leave it? Looks like it turns into a hardline of some sort.

There are also a pair of lines that run to the thermostat housing. Are those supposed to be blocked off or connected to a vaccum source? I broke one of the damn nipples off so I hope they are to be blocked off. Looks like they run to a sensor???

SO, in general, you remove all lines off the TB, disconnect where they go to and remove the canister right?
Thanks, John.
