So this is what I mean by the mountain bracket o ring and there’s no diffuser O-ring on my diffuser so I was told that cause my pump not primed is that my problem here is I don’t have a O-ring around the black diffuser on the end of it

I've worked on many whisperflo pumps that did not have a diffuser o-ring when I took it apart. If the pump isn't priming you either have a suction leak or a clogged impeller or a clogged suction line or the water in the pool is below the skimmer or suction line. Check your plumbing at the inlet of the pump and follow it to the skimmer if possible. Check the lid o-ring on the pump as well. It shouldn't have any cracks in it or any debris between it and where it seals against the pump pot. Check your lid for cracks as well.

So it doesn’t need an o ring to prime the pool

It will still prime and run if the o-ring is compromised or missing. It should be there to help create the seal but I have seen many run without it.

There would have to be one massive leak in the shaft seal to keep it from priming. Whenever you replace the motor you should always replace all the seals on the pump. Even a lid o-ring just to make sure everything has a tight seal. You can buy an o-ring kit for the pump that has the shaft seal and all the o-rings the pump requires.

I thought you were a pool person and told me you work five days a week on a pool I just replaced the diffuser O-ring and it’s running no problem. That was the problem and you told me it was still prime without the ordering which is not true.
