See my thread on "X7 Fat Sack issues". It may interest you. My first action to improve your situation is fit a new "Green" impellor to the pump.It transformed my system. On my 2005 X7 pump is mounted on top/behind the fuel tank under the rear storage deck. Changing takes 10 mins. If that doesnt work then start investigating other possibilities. in my thread you might like the modification Ive made.
