2000 OX66 150hp fuel injection. Seem like I'm having a fuel leak. Do these motor got a fuel pressure relieve after you stop the motor. I was cleaning the inside my motor with the key on position to hear the high pressure fuel pump build up pressure . I fire up the motor for a few second then shut it down. I happen to look at the fuel rail that connected to the VSt fuel hole .I notice small amount of fuel dripping down from the bottom fuel rail where fuel hole connected out from the vst. Is this leak common?

It is not normal for any amount of fuel whatsoever to leak.
You need to get that leak fixed ASAP. A little bit of gasoline creates a lot of fumes. A lot of fumes can result in a big bang followed by fire. -
Thanks for the reply . I will get it fix asap. Could you point me to the right direction on what could possible be leaking.
