Drain the fuel and start with new you probably have and leak in the fuel system if you have bubbles the soft lines from the tank to the filter are prone to leaks and they are hard to find as the system is under a vacuum. Might try air in the fuel filler neck and have someone looks for fuel leaks, use caution and don't use much pressure on the fuel system some use the air output side of a wet & dry vac as the air pressure is less pressure. You may have to replace or rebuild the filter head and primer they are known to leak also.
