1967 New Yorker gas tank gurgling and spiting out gas

Wondering if anyone has experienced their gas tank gurgling/bubbling and spitting some gas from underneath the car after they shut it off. I don't recall this happening before. I backed the car inside my brother in law's shed to work on it and heard and saw it doing this. The tank and pick up are new as is the fuel pump. I put a new plastic see through filter from Napa on and it barely shows any gas in it. I read someone saying the "glass filter" are no good? Taking any suggestions....
