So i have a 1982 jaguar xj6 and recently just had a new fuel pump, fuel filter, battery, alternator, volt regulator, and spark plugs. Been trying to bring this car back alive but its still giving me hell. One day i noticed a gas leak from my hose that goes into the charcoal canister. I do beleive i put too much gas into my tank which fed gas into that line to the canister. My car stalled out on me one day. It always starts up but the rpms are not steady at all and eventually dies quick especially when i put it into gear or hit the gas. I put some iso heet into the tanks and it helped for three days and didnt give me any problems. It stalled again after so i put more gas treatment/water remover in it but didnt help this time. I filled with shell gas 93 v power. No lights are on the dash and all the meters are checking out good. The car emits more smoke than usual from the exhaust. Can it be gas thats in the charcoal canister causing it to stall? Any help is appreciated and can explain more if needed. Thank you
