    that hose that underneath that yellow valve hose goes to the front pump. Then I have a fuel bowl that hose goes to the front of the pump as well. Confusing wondering if that needs to be open or closed.

    I have only seen that valve on a MBN and don't know its function, but my wild guess is since it comes from the return line, to recirculate warm fuel to the system in cold climate, if it was me I'll keep it close, I live in Florida.
