That tiny little o-ring around the pin is a very troublesome item. When they leak, the fuel pump sucks air from around the pin. There are two sizes of the o-ring, early ones being smaller than later ones. The early ones are especially prone to leaking. It is removed by removing the core plug, then sliding the pin & spring out. Then stick a punch or something in the retainer #16 and rock it out. Use a hammer and screwdriver to stake it back in.
