    1st thought is that the fuel lines didn't get plumbed in right. Make sure you got the three lines going to the tank correctly routed.

    2nd thought is that the fuel tank is overfull. If you just filled the gas tank, and you're one of those who likes to squeeze every last drop you can into there, you just may need to drain a little gas out.

    Thank You MrShorty this has happened twice and the first time the gas was on a half of a tank and the next time was when it was completely full so I will check the lines is there any particular place to look up where the lines go my father in law helped me put this back together and we had another person helping also and the other person put the lines back on
    Thank You again
