Dual soaked charcoal canisters - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Willi2ds · 06-16-2016, 12:26 AM

So I've searched and couldn't quite find what I was looking for. I have two canisters, I'm assuming that's because I have dual tanks. The bottom of both of these are saturated with gas, first thought was to remove them both but I really don't want the garage smelling of gas all the time. So my questions are:
Can I just do just one canister and use tees to join the tank vent lines?
Has anyone used one successfully out of a newer vehicle?
Rebuildable? I've heard of cutting apart and using fish filter charcoal and regluing, not sure how durable this would be.
If nothing else, any fairly cheap replacements?
Thanks guys

If they are soaked you have liquid going out the vent line. That needs to be dealt with before you replace the cans.

Usually liquid in the vapor vent lines is caused by overfilling the fuel tank. If the fill pipe vent is malfunctioning you can force liquid into the canister vent lines too.
