Fuel shut-off solenoid leaking. Ideas??

Depending on the engine, you could get a nasty hickey on that hand. Or worse. Some folks have tried to use things like a cushion to block off the air intake, and then watched the engine inhale the entire cushion. With a compression ratio around 22:1 a medium sized diesel in good working order can snarf down a lot of things.

The post we were referring to is a good example of why you need to take Internet advice with a grain of salt. Here, someone is recommending a procedure that could leave someone with a permanent injury.

Thanks Jim...and bless you for dissing the Westerbeke part at $600! What a shock that was...esp since we just paid $1000 to have the fuel injector pump rebuilt. We are in the Bahamas/Abacos so not sure I will be able to find a pump shop here. I will call the shop in FLL tomorrow and hope they can help. Happy Easter!

ok....your trouble shooting indicates that it is NOT the solenoid. The leak appears to be from an adjustment screw in the governor cover above solenoid. Noiw what?

If its the pressure switch fix it, you don't want to bypass it. a little thread sealant might work. If it's the shut off solenoid bypass it till you can get another one. the engine is stopped by a shut off in the injection pump...mechanical not electrical.

It looks like the leak is coming from an adjustment screw in the governor cover. Above the solenoid. Not sure what the screw adjusts. Thoughts????

Believe that would be the full load adjusting screw. There is an excellent descriptn of the VE pump here:

Also looks like there is a seal ring that seals the screw, available in a kit from these guys: https://www.hansautoparts.com/BoschRebuildKit.aspx for 16.00

Thank you. I have an email in to the company that reconditioned the pump in December. I hoped that I could back off the screw and apply thread sealant, but it sounds like it may require a new seal.

Dear Hellow Sailor,

A bit of sour grapes?

Banshe-
Miriam Webster and both agree that "sour grapes" is totally baffling here.


def: ": disparagement of something that has proven unattainable <his criticisms are just sour grapes>"

There's nothing to attain, much less unattainable.

Jim,
You are right on. Thanks, The company that serviced the fuel injector pump 3 months ago is sending me a supply of replacement o-rings. For now, I was able to secure a hose over the screw and divert the leak to a small container.
