Hose routing questions : charcoal canister/purge valve

My5ABaby · 04-07-2009, 07:10 AM

I put my charcoal canister back on (why not?) and want to make sure I'm getting the routing correct. I'm running the nipple coming off the block straight to the charcoal canister (PIC1 and PIC2). This will work fine?

Also, there's a nipple coming off the oil filler neck (PIC1). If I'm reading the diagram correctly it, in stock form, goes to the purge valve which then goes to vacuum. As such, can I just route it straight to a vacuum source (PIC3) since I'm not sure if I have a purge valve lying around? If I do have a purge valve, the 2 vacuum tubes coming from the purge valve go to the nipples on the front of the UIM?

Thanks...

I'm curious on why you want to put the charcoal canister back in. I honestly couldn't help you off the top of my head, but I'd need to look at the fsm. I was under the impression that the C-Canister was for start assist and to relieve pressure from the gas tank on hot days. If that's the case, hooking it up to the ventilation ports of the oil isn't going to work right... but then again, I may be mistaken.

I'd rather vent the gas fumes into a charcoal canister than under my hood. I've had a problem with an exhaust smell in the cabin for a while so I'm doing whatever I can to fix it.

dont mean to thread jack but since we're on topic, the hoses from the c-canister are supposed to be rubber? i put on a plastic vinyl hose on there to get rid of the cabin fumes (didnt have one one prior) but i still get fumes cruising with the windows down.

also, the nipple from the oil filler neck..right now its open vented...what should i run for that one? also, does it cause fumes also?
