    BF200 Leaking fuel from vapor separator

    Thanks for the ideas, guys! I checked the solenoid valve. It is not stuck open and continuity values are within spec. I have not checked yet to see if the valve is being commanded to stay open by the ECM. I traced all of the vacuum and fuel lines and their connection to the vapor separator...

    BF200 Leaking fuel from vapor separator

    Thanks for sticking with me on this! I’ll check the water jacket and recheck float height. Regarding the fuel cutoff solenoid, is there a good way to check that? Does this solenoid prevent fuel from going to the vapor separator with engine off? One thing I’ve noticed: with engine off, I can...

    BF200 Leaking fuel from vapor separator

    Low pressure fuel pump replaced about a year ago. Diaphragm failed, allowing fuel into engine oil. Could this pump be overpowering the closing pressure for the needle valve at higher RPM? Could temp of low pressure side of vapor separator be getting too high, causing pressure to rise in the...

    BF200 Leaking fuel from vapor separator

    Just to describe the problem more clearly: The engine runs great. On initial start and idle, there is no evidence of leaking fuel. After running for about 30 minutes with engine speed around 4000 RPM or so, and docking at idle, a sheen appears in the water.

    BF200 Leaking fuel from vapor separator

    Vapor separator overflow is on low pressure side of fuel supply. The relief bolt is on the high pressure side. Am I correct?

    BF200 Leaking fuel from vapor separator

    Manual says float height is to be 29-34 mm. It would seem measurement location could be critical. The overflow problem seems to be happening after the engine is run for 30 minutes or so.

    BF200 Leaking fuel from vapor separator

    I did, but I’ll pull the vapor separator to double check. I have a clarifying question. Manual says to measure distance between float and cover “at the tip of the float”. The drawing is confusing, because it’s not clear which tip is being measured. Closest to the needle valve? Furthest from...

    BF200 Leaking fuel from vapor separator

    BF200 with 350 hours. Fuel is leaking from overflow of vapor separator. Have already replaced needle valve and cover (valve seat).
