Is there some reason you feel that it needs a super cleaning ?

I just 'treat the fuel' and fuel system fairly conservatively.
I might put in Berriman's Carb Cleaner ..........I buy it in the gallon can
, there are instructions on the can for how much to mix in.
I use Lucas Brand Fuel Injection Cleaner some.  Any van or car that I get
...........I get some fresh fuel in the tank right away, and some Lucas fuel
treatment.

I also notice on the side of a gallon jug of Marvel Mystery Oil it says
'fuel system lubricant' ............with instructions on how much to add to
gas.
I treat fuel systems with those 3 primarily.

I think it's smarter to treat something gently over time, rather than try to
blast it hard with a 'super cleannig' ........that's a great way to create
problems where there weren't any before the treatment.
'easy does it' so to speak.
