Hi guys,
Given my recent issues with a large amount of scale in the upper and lower fuel tanks from oxidization, I have now ordered a new fuel pump and filter from Partzilla and have managed to clean out the lower tank to the point where there is no discolouration of fuel when it is filled.
Whilst I am awaiting the new pump and filter, I still need to clean the scale out of the upper tank.
What methods and/or products have people found to work the best?
