ACDelco Charcoal Canister Plumbing with Sniper Help

[DrRock]

Hello All, Someone here posted a nice hand drawn picture of their plumbing schematic for using the ACDelco canister with a Sniper. For the life of me I can’t find this thread. I think the diagram was buried with some other topics but I haven’t had any luck finding it.

Can anyone point me in the right direction or provide a schematic for this canister and the check valve? If my memory serves me right, they also used a T fitting into the PCV vacuum line but beyond that I can’t remember what else was specified.

Thanks in advance for the help!

I know the drawing you are talking about, but don't have the link saved. Post 919 on this thread is helpful.

Awesome, thanks a ton. This is just what I needed. I’ve searched a bunch and still can’t find that drawing..

I looked for a while earlier too and can’t find it.

I can share pics of my setup that I’ve been running for a year or so but it’s modeled after the post in that thread I shared. I went through a ton of tank pressure issues and this solution fixed it.

I’m currently not having any tank pressure issues… yet. That said, I want to do this correctly so if you have pictures that’s great but don’t go out of your way as I can follow the ones in the post you referenced above. I’m also running the GM pressure regulator back near my tank so I don’t have hot fuel returning from the engine bay into the fuel tank which can’t help matters.

Are you asking about the VCV or the Purge Valve or ... ?

No, there was a diagram using a GM check valve to hook up to the vacuum and AC Delco charcoal canister. I’ve got a sniper so my only vacuum lines that exist are for dizzy advance, PCV and dizzy vent.
