Thanks Irving. So the points of the gas tank that are sealable are the cap, fuel cap, the in and out lines...What about that line that runs under the tranny tunnel? Whatever that vent thing is...should I cap that? Ill have to find that crack by feeling around in the tank considering I don't really have time or resources to drop it.
From what I understand with the o2 sensor is that under 3k it controls your AFR's but in WOT it has no effect. Also at idle it will have between 0 and 1V which is determined by the resistance it detects via sniffing the fuel in the exhaust right? IIRC 0v is lean and 1v is rich so to test my o2 sensor I would probe it and watch my voltages in relation to my AFR on the wideband right? I just read somewhere the medium for o2's is .45 and anywhere below or above that is lean or rich.
Sorry just thinking aloud and if it's right it will be a good future reference...opinions?
