I have about 50 gallons of fuel
that had been left in jury cans while on the hard
. One mechanic
mate said it's fine. Another mechanic
mate reckons that it's no good.
My 20 year old SS fuel tank
has a blackish/greenish gunky film on the bottom and some on the sides. I used a custom rigid hose with a fuel pump
with two inline filters to 'vacuum' it all up as best I could... but there's a baffle so I could only get half the tank.
I've seen worse on other people's tanks
and they never vacuumed theirs out.
Previous owner said he never saw any of the stuff in the bowl of the Raco and that he really never thought of it as a problem... just normal boat tank situation.
