Thread: Charcoal Fuel Vent Canister!

Tweet

Ok, so I've been doing some more studying on the charcoal vent canister thing and I have a few more questions. I snagged the venting device from a 90's Mustang and it looks kinda like a plastic version of the pcv valve . It was mounted with a rubber grommet in the smaller hole in the highest area of this 90's mustang tank http://c1385772.r72.cf0.rackcdn.com/lrs-9002bk.jpg It's called a vapor valve and it looks like this without the rubber grommet http://c1385772.r72.cf0.rackcdn.com/lrs-9593a_1332.jpg I don't think gas ever touches it. If I try to mount this unit in the top of my in-cab tank, it will probably dip into the fuel when the tank is full. Also, the line coming from it will have no choice but to go down under the cab to the chassis as it runs to where the charcoal filter is mounted on the chassis in the engine compartment. I assume that's going to cause problems, right? I don't know how or if the factory charcoal filter can handle the possibility of fuel running into it can it?

I assume I'll have a similar problem of the "unit" dipping into the fuel if I move the tank under the rear of the bed, though there won't be the elevation drop because the tank will be at frame level. I could use the type of "roll-over valve" that Dave used on his car but with the under-bed tank, that valve would also be partially submerged in fuel on a full tank unless I raised it, right?

Would appreciate some help sorting this out. (Yes, Dave, you'll be happy to know I'm giving more thought to moving the tank out of the cab!!)
