I have 2 of these the other is in the car for now as I plan to add the GT500 fuel kit down the line. I used this for roughly 2500 miles, I switched out this pump for the other and I was getting the same problems, it wound up that I am just running out of pump at WOT. Located in Garner, NC, price is $100 shipped.
