Can you flush & clean the fuel tank while it's still in the car? I've been having an algae or fungus problem and just had a lot of water & coolant mixed into the fuel as well.

I'd rather avoid the hassle of pulling the tank. Especially since I will have to remove the trailer hitch too, which is hassle too.

I removed both fuel lines and pulled the tank strainer.

I then flushed the tank with about 2-3 gallons of RUG into the filler neck and out into a bucket under the strainer hole. Which I hope removed99.9% of the water.

Then I capped the two fuel lines and installed the strainer.

Filled the tank with RUG and BioBor and will let it sit a couple days. Which I hope will kill any fungus or algae that may be in the tank.

I plan to drain the tank a couple days later and flush some more RUG through it to rise out any dead algae & fungus. Then put it all back together.

Will a full tank of RUG wipe out any fungus & algae?
