I have a 1982 300TD that sat for ~10 years. While driving home the fuel filters kept clogging. I ran through 3 sets of inline and canister filters in 450 miles. Here are some photos of the 2nd inline filter.
Is that Algae? It looks like mud.
It seems like there is some contrasting advise as to what to do about about it. A lot of trusted people suggest using Biobor JF to clean the tank while it's still attached to the car but I'm not sure if it can handle the level of infestation that I'm dealing with. Should I try it and see or should I go ahead and remove the tank and then add Biobor to clean whatever's left in the system.
As always, Thanks for your replies.
