    I just bought this engine and it ran good. The third time I had it out it quit. I took it in and they replaced the high pressure fuel pump. Took It out again it ran good but quit second trip out. Called the dealer and they suspect the low pressure pump is out. Just wondering if anyone had any thoughts or had a similar problem

    Remove the antisyphon valve from your fuel tank, or replace it first.

    It's that aluminum connector that your gas line is connected to at the top of the gas tank.
