Ok. I've searched and seen that this topic has been touched on a couple of times here, but no-one has really addressed exactly what I'm looking for.
I recently realized that my fuel system is sealed. I remembered that when I dropped my gas tank I saw that the two vents were connected together with a piece of heater hose / fuel hose. At the time I didn't really think anything of it, but the memory remained. The other day I ran across a thread talking about keeping some type of tank vent in-tact for proper operation and it really got me thinking. I checked the gas cap and found that it was not vented, so with the sealed top vents and an non-vented cap, I'm assuming I've been trying to run my car with a sealed tank which probably means my fuel pump has been working overtime and it may explain why my fuel pressure climbed ~ 10psi (different gas cap positions maybe (more sealed / less sealed)) a few months back (I haven't run the car since). Anyway... My car's been in the paint shop for a lot time and now that it's out I'm trying to figure out why it runs rough and I can't help but think that this may be negatively impacting my engine's operation.
So... I'm looking for the best solution. When I thought this through last weekend I did the first thing that came to mind and ordered a little vented Stant fuel cap:

Is there a better solution? Should I try and rebuild the stock system with a charcoal canister, or make some type of safe vent without a charcoal canister using check valves that connect to the tank vents?
Any feedback is appreciated
