I converted from TBi to carb, and currently the charcoal can is still in place and plugged into the tank line.

The vacuum line is currently capped off, but the tank line (as previously stated) is still connected. I'd like to know if this will cause problems like in-tank pressure and whether or not I can alleviate it with a vented gas cap.

Thanks in advance, J.

 

I removed mine altogether - I just ran a fuel hose fro the third fuel line to out under the car to prevent any possible fumes or liquid leaks from happening in the engine bay where there are hot things. No pressure problems with mine - can't remember if I ever replaced the gas cap or not though.

I replaced with a coolant overflo/washer resevoir tank from a Ford Explorer - matches the size of the battery on the other side (symetrical), looks good, and got rid of those huge (now yellow and dirty) jugs on each fender.

 

Is the purge valve still connected? If so you'll have problems, otherwise you shouldn't.
