Re: HPDI water in fuel

After you flush tank Drain the VST and hook up a remote tank and keep priming new gas into fuel system, keep draining the VST until no water is present in VST then change inline fuel filter on engine. If it is the new style of filter (little cogs 360 degree) below filter top, take it to a dealer, special tool is required get off and back on. Install water seperator!

clear the fuel filter cup,if its a thread in model, no special tools required a strap wrench will work.
be aware that ethanol swells the cups that thread in and sometimes they have to sit on the bench about 24 hours before you can reinstall them.
drain the VST.
start the engine on a known clean fuel supply.
allow it to run in gear with the prop removed.
after 10 min or so shut it down and let it sit for 20 min.
drain the VST again and change the medium pressure fuel filter.
the special clamp MUST be used at reassembly DO NOT use a standard hose clamp.
it may take a few cycles to finish clearing the HP pump and fuel rails of all the ater but its not bad.
