Hey everyone,
I've been trying to figure out what to do on my set up for the charcoal cannister, VSV, evaperator seperator setup. Read a lot of threads on this, but I'm still not sure what to do. I've been a getting a little pressure in the tank when I run it. I know my VSV is dead, so I did what I saw in a thread about this in the 40 section a while back, where I ran out of the canister into the bottom of the air cleaner, figuring there'd be a little pull all the time. I tested the canister and it flows good. I realized yesterday that the check valve at the seperater has to be bad as I tried to suck and blow air through it and lets a tiny bit of air through both directions, but certainly isn't working like a one way check valve and has so much resistance there's no way the pressure from the air intake is gonna overcome it, which I suppose makes sense that the pressure is building up. I'm going to try to track down the right check valve, although so far all I see is one for 75 and later. I'm thinking it's probably the same, but will pull it later to make sure. (see below for what I'm seeing online)
So my thinking at this point was that since my VSV is dead, I'd just connect the output of the cannister straight into bottom of the carb where the output on the VSV sent it (red hose) back when it worked. I know this is supposed to only operate when the truck is running 15 mph or more, so my question is, is this a terribble idea to run it straight in all the time? If it is, what else should I do? I saw a supposed rebuilt VSV on ebay, but I have no clue if my speed sensor set up works either. I'm not having any gas fume issues, but I do need to deal with pressure issue and I'd ideally like to send it back into the system to burn, although I have no smog to pass in New Mexico because the truck is 30+ yrs old, so I can literally do whatever. I just want it to not smell and not stress the tank/system. I saw guys doing vented gas caps, bypassing the system. Any thoughts are helpful. Thanks!
