Good luck sorting it out I know how frustrating it is getting a new boat and having trouble right off the bat.
BTW where are you located maybe I can lend a hand if your close
Problem finally solved. It was the fuel pump after all, you were right Johnnye23. It took some tweaking to get the new pump to work. I delayed installing it for several days as I thought I had lost the o-ring that seals the top end of the pump to the fuel line. Turns out there is no o-ring in that joint at all, just a flare on the fuel line and metal to metal seal with the pump. So, I installed the new pump at lunch today and it leaked at that very joint where I thought I had lost the o-ring. So I took the female end off the old fuel pump and put it on the new pump and voila, no fuel leak at all (there is an o-ring between the female union on the pump and the pump housing but not between the female union on the pump and the fuel line). Took the boat out to the lake after work today and found perfectly flat water and not one other boat on the lake. My buddy and I ripped it up and had no troubles at all. Very happy. Now I am going to fix this baby up and sell it in the spring if repairing my 02 xstar doesn't break my bank account. Thanks for all the posts and help, good to know you all are out there.
