fuel pump access hole cut. Pump issues

I have had a lot of trouble with my car starting rough. The cause is fuel returning to the tank after i turn the car off. I first tried putting a check valve in line after the fuel filter, that didn't work probably didn't use a high enough quality unit... Now I've tried replacing the fuel pump, but rather than dropping the tank i cut an access through the drivers side passenger floor, pulled the pump out, and realized that this car doesn't have a pump in the tank. Its a fuel pickup (mesh bag lines and fuel gauge float. I already had a actual pump ordered because i called fcp and they gave me the part number, i didn't end up getting it from them, i got it off ebay using their part number. I also verified the pump i got off ebay looked the same as what fcp and several other sites say i need. Im lost wondering where my fuel pump is and where the one way valve in this systems is. So if anyone can follow that story is there any advice?

This is the pickup i pulled out of there.

This whole i cut. Ooofda.

I got all nervous cuttin over the gas tank and about 2cm from a fuel line so i wet things down abit as i cut

The pump fcp and other places said i need for the awd. part no 9470674

Wrong side. Your main fuel pump is on the passenger side, what you removed is the aux. "fuel pump" for in tank transfer.

Plus my fuel gauge float is on aux pump i removed and the fuel pump i bought has it in it also.

Do i have a float in each tank?

If you don't have a fuel pump on the passenger side I'd really like to know your car ever worked in the first place.

And yes, you have a float in each side of the tank. There is only one tank as such.

Ok so i need to look around more on the passenger side for a pump.

Also, Is the one way valve in the pump?

holy moley that is more complicated than a p80! I thought the double pump set up on the B230s was confusing until I saw this
