EFI fuel flush


Recommended Posts

I'm getting ready to drive my 280 now that the heat has lowered in Alabama.

Anyhow, plans so far are to remove tank plug to drain old fuel then run 2.5 gallon gas can straight to the pump, bypassing the tank. Hopefully the return will let new gas to flow back to the tank and into my catch basin never going through the injectors. I'm thinking Seafoam for those after replacing my 2 fuel filters. The OE can and the G3 out of the tank.

Is it that simple? Thanks for any input. I've forgotten more than I remember...
