Default How to turn off fuel pump MX6.2L MPI with Cool Fuel

Hi. I am winterizing a Mercruiser 2001 MX6.2L MPI engine with Cool Fuel.
First time winterizing a fuel injected engine. Book says I need to turn off
fuel supply, take out water sep fuel filter, poor 2-cycle oil into it,
reinstall fuel filter, and run engine until it stops.

Need to turn off the fuel pump to do this as there is no shut-off valve (why
do boat builders never put fuel shut off valves in boats anymore). There is
no breaker for the fuel pump. Anybody know a trick to turn off or disable
the fuel pump to get the job done?

Thanks,
Chris

Unplug it if it's electrical.

Later,

Tom

it wont run with the fuel pump unplugged, no fuel pressure = no fuel =
no run.
re read and understand a little better the procedure or just add
stabilizer to an accesory fuel tank with storage oil and connect that
to the engine where your existing line connects. run the engine on
this "pickle mix" until you are satisfied you have coated everything
then simply turn the engine off. definately stabilize the fuel in your
tank as well. good luck

Yeah - that's the question - how to turn off or disable the fuel pump.

That's what he asked.

That's what I thought. g If I unplug my fuel pump while it's running, it
continues to run until it's fuel starved. That way, I know there's no fuel
in the carb or cylinders. Treat what's left in the tank, and that's it.

you both misunderstand. if it is infact an mpi motor it will shutdown
exactly when you unplug the fuel pump. the fuel pump supplies the fuel
pressure that keeps the fuel rail primed for injector pulses, the
motor will shutdown when the electric fuel pump is disconnected.
contact your dealer and get a recipe for a pickle mix and run this
through your engine, no need to run anything dry. startup in the
spring will be harder then normal and smoke will be prevalent but it
will start and everything will be fine. your main concern is not fuel
conditioning however, it should be untreated cooling system drainage.
parts such as the exhaust manifolds, power steering oil cooler, the
pickup pump and lines all need to be drained to prevent freezing
damage. the raw water side of the heat exchanger is another item that
will freeze unless drained. another winterization tip, always store
your boat with the drive in the down position, this will prevent the
bellows from cracking and prolong the servicable life of the bellows.
hope this helps. good luck.

Well, see - just goes to show you - I didn't know that. Learn
something new everyday. Then again, I've never winterized my FICHTS
myself - I have it done only because I'm fraidy scared of working on
injected motors. Then again, FICHTS aren't inboards.

Er....never mind... :)

Thanks for the information.

Take care.

Sorry, I didn't know we were talking about a fuel injected engine.

Not true, the carb bowl will still be half full. Try removing the drain
plug after the engine stops due to fuel starvation, you'll see what I mean.
