I did a yaffe tank on my 2002 king. I am blowing the ECM and Fuel Pump fuse only when I have the mounting bolts in holding the tank to the frame . this leads me to believe its in the tank. if the tank is on the cart or just lying on the backbone it primes fine when I hit the run. As soon as I contact the bolts to the frame I have a short when I hit the run button. Where should I begin??
