EFI Foging Procedure

[Mr. Grumps]

2000 Mariah 4.3 EFI Mercruiser.<br /><br />I have seen posts that say a remote tank should be hooked up and engine run for 10-15 min to Fog a<br />EFI engine. My question is how do you hook up the <br />remote tank to the filter housing?? I have the Merc manuals but can't seem to find how to do it.<br /><br />Thanks for any help you guys can give to a Newbie.

By disconnecting the main fuel tank rubber hose from the fuel filter housing and connecting your portable tank to the fuel filter housing input with a rubber hose connected to it?

See this thread, I thought that was how you fogged a EFI engine but it seems that there is TBI (Thottle Body Injection) I dont know if it applies to your motor but its worth investigating as it seems much easier.<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=24;t=009489 <br /><br />Regards<br /><br />Chris

That should be a TBI which basically has an electronic carburetor. Just fog like you would a carbed motor. Many other EFIs have intakes that won't allow good oil introduction into the motor.

TBI you can fog like a carb, MPI you have to run the mixture through. To much fogging oil in the cylinders of an MPI engine will also damage the injectors.
