Hi everyone. Experienced Newbie here trying to get my truck back together. Bought a new tank and A Delphi Fuel pump # FG0086-11B1. Both the new tank and fuel pump came with an o-ring but i cant get it to push down to even come close to getting the lock ring installed. If i remove o-ring i can but if i blow into inlet of tank it leak air out around pump. Any ideas ?

Grease up the o ring. It will go together. Another set of hands will be helpful. You need the o ring !!!!

Lack of a seal there could cause numerous problems. One of which is when you go to fill it up, after the tank is full, gas will pour out that gap until you notice the waterfall under the truck and shut the pump off
