I was in the process of dropping the gas tank to replace my fuel pump and found the nozzle to the vapor vent was previously snapped off. This is located at the front of the tank. There is no way to repair and I am confused as to whether or not it is replaceable. It does not twist out and appears to be epoxied into the tank. Is the only solution to replace the entire tank? This is a plastic tank. Thanks

You could get creative and find some other means of epoxying another nipple on for the vent. Use the same stuff to seal off the other hole.

Thanks Mike-worth a shot. I was thinking of using some thin metal for the nipple, possibly brake line? drill a hole through existing plug and epoxy it secure. There was a lot of unknown black substance in the tank and it appears that plugged up the fuel pump. A friend said there were issues with the plastic tanks and the ethanol used in gas now that would degrade the plastic. I don't know if that is true he'* wrong half the time.

Ethanol degrades rubber/latex. Not plastic. Otherwise, millions of plastic gas tanks sitting in garages would be rotting and spewing gas all over.

It'* not pretty but went with the brake line/epoxy theory. I used 1/4 nickel alloy brake line instead of copper as copper may be affected by the gas I was told. I cleaned the valve plug then drilled the hole open again to be able to insert tightly a 2" piece of the brake line with the flange on one end. I also lightly sanded it along with the surrounding plastic for better adhesion. Then I painted the epoxy on all around hopefully to be airtight. When I inserted the brake line I pushed all the way in then backed out a little for airflow. I hope this works-if after a couple of weeks driving and no codes I'll post back-maybe someone else might want to use this idea. It seems to be a real solid strong fix at this point for about $10 instead of a whole new tank.
