Did some pulls yesterday and my afr was perfect at WOT

Now again they went up 2 points, its 13.2

What could the problem be?

The fuel pump is moving around inside the canister after using the car a bit.

Maybe O rings are bad? There's not much more that could be.

When you close the canister, do you have to push down really REALLY hard?

Also, if its the loose pump, you should see even higher AFRs on higher gears.

When I finally solved my issues I had to push down HARD. As a last resort, you can drill small holes by the pins area and tie wrap it all tight, that way it has nowhere to move.

I find it so ODD that you have white spacer, 2 O rings, it snaps into place but still FP moves around. Look at the O ring condition. Maybe they've gone bad.

o rings were perfect

I might removed the white collar and do 4 orings

I also don't have a FP filter as Visconti threw it out saying that I don't need it

Maybee that is why your first pump failed, and this one is already acting up.

Could also be long term trims. I have verrified that the ecu WILL apply negative long term trims under wot. Would be worth it too take a quick log.

Also, as i mentioned, without the soc filter you may be sucking up some debris. Could be it is shifting around as mentioned, or maybee the R&R is clearing the inlet temporarily... i guess i would lean towards the pump shifting but still try and get a new soc... whomever makes the pump should be able to get you one.

without the damn filter on the bottom the pump doesnt that added pressure pushing it up into the housing thats why your losing pressure and your assembly closed so easily wtf would run the pump without the inlet filter not to mention not measure the installed height of the pump assembly.
