I am having a lot of trouble with my Volvo I/O and I was told by a
mechanic that an EFI should not be "fogged" to winterize it or it may
foul the plugs, fuel pressure regulator and fuel injectors. I am
having a problem with all of these items. He said to winterize the
motor just disconnect the fuel tank, attach a seperate gas can with
gas, some outboard motor oil to lubricate and Stabil. Run that for
about 15 minutes. Add Stabil to fuel remaining in tank, drain water
add ati-freeze and that's all. Any comments on this?? Thanks Tom

I don't see that fogging will have anything to do with the pressure
regulator. And at most it will sit on the outside of the injectors. I
would not have any problem fogging an efi engine. The main point of
fogging is to get some oil in the cylinders for storage. You can also
remove the plugs, squirt a little oil in each cycliner, crank it over a
few times, and then put the plugs back in.
