Hello, I have a 2004 Rx8. Went to pump gas yesterday and saw a bunch of gas coming out from below the car. Lifted up the rear driver seat and saw gas flowing out of the little tiny holes on the retainer cap. Popped open the fuel pump area and saw that it's about full tank already. Threw in another o-ring on. After trying to clean up that area, I started the car up and drove an hour home. Fuel gauge reads half tank at the time of pumping it up, but I am not sure if this is correct. When I got home it was on E with the orange light lit up. I am pretty sure it should have more gas than that.

Today I thought I'd tackle the fuel pump again. The o-ring is there, but I am not sure if I am installing it correctly. I have it installed under the fuel pump assembly so fuel pump would be on top of it and then the big plastic cap over everything. There was still plenty of gas. I want to say 1/4 of gas left in it. Pumped $20 gas and the gas flows out of the holes again.

I would like to get this fix. Please help. Thanks!

EDIT:
Here's a video from earlier:

Sorry for the small size video. Had to hold the gas pump while filming this just so I don't have a flood beneath the car.
