I HIGHLY suggest people stay away from FEP encapsulated o rings to do this job. Bottom line the big o ring is just too THIN to seal correctly. Shoulda thrown the thing in the garbage. Will be rebuidling again, and replacing just the 2 o rings that are required the big one and the smaller one that comes off when you seperate the 2 halves of the pump (4 bolts)
When you take it apart, check to see if the big one is damaged like it got pinched. There is the tiniest of grooves around the big ring and if it's not seated right, the o-rings will get sliced (someone posted this a while back. As far as I know my FEP rings are doing fine. Do keep us posted.
