I've no idea of what the vent pressure is, but I can't imagine the number is very high. Pressurizing the fuel tank would start forcing fuel through the tank pickup, as well as causing cap blow-off when removed and possible splash at the same time. I don't want any pressure in a fuel tank, period.
Yup, what Mike said! Pressurized fuel tanks, no good has come from them. Dangerous. You should run a vented cap, ever seen a full gas can sitting out in the hot sun? Try to open it....you'll have some of that gas on you....this is exactly what Mike's saying. I would rather have some evaporate than to take a bath in the stuff. If your tank is covered and kept cool, this will help. Painted reflective aluminum or bright white helps. THAT, in combo with the two way cap will work....but a vented cap is best. But, vented is also a safety hazard in some ways. You can't smoke around that tank, do any cutting with a torch or plasma or you might blow yourself up. And gas fumes sitting at a redlight and sloshing upon a quick stop...just a touch might come out of a hole in the top.
Is the pressure thing fixed? Did you get her started today? Is she still running rich? Well, if I were going your way I'd give you a hand, maybe one of the members local to you might help you out. If not, we'll eventually talk you all the way thru it. Gotta go eat, will check back in a little....
