Re: Bio Sludge in fuel tank
I imagine that there may be some degradation of the fuel lines if the high concentration MeOH was in the system for a long time. I doubt that the impact using a low concentration would be significant. So, if planning to do the 'shock dose' (10% MeOH), that it be done in a short time-frame to minimise impact on hoses.
I can't do it with the engine off, unless I leave the ignition on, as the shut down valve prevents circulation thru the IP when Ign. is Off.
This last point is one of concern with a 'shock dose'. What we need is someone who has an issue with the TS to try a shock dose to see what happens. I don't do many Km in my car, so a 'Shock dose' would sit in my fuel tank too long for my liking. I will try a 'maintenance dose' of 1% in my biodiesel.
How can I tell if it works?
Someone who has a sedimenter (aka TS trap) might like to see what happens to the TS when a 10% solution is pumped thru an impacted TS Trap. Does the level of TS drop with the 10% solution being pumped thru it?
Any volunteers?

Aside from the fact that it is highly flammable and toxic to humans, what are the other risks using methanol in this manner? Is it likely to damage hoses or nitrile or Viton seals in the pump in concentrated form? Assuming you flushed it afterwards with biodiesel to ensure no significant quantities of methanol make it into the combustion chamber, would it be ok?
What about turps? Better or worse?
And what about a residual maintenance dose added to the fuel on an ongoing basis to keep the TS dissolved. Similar to a 10% addition of ULP? What would be a safe % of methanol to try?
Is there a risk of dislodging a heap of TS that has been accumulating in the fuel tank over the years and sending a big plug of it towards the IP? Hopefully the sediment trap and filter would catch it?
