i bought my 1986 TRX350 A last week. Found moderate rust scaling and red goop inside the fuel tank. Looked for a Sticky on fuel tank cleaning and preservation.

Pulled tank and degreased with about a cup of Dawn and a 2 gals very hot water. Then filled it halfway with straight vinegar–loosened almost all the scale so now i am ready to do a final clean. What is the wisest method? I see the Kreem kit but is it really necessary to coat the tank? Concerned about blocking the internal fuel lines.
Does anyone have pics of the fuel tank plumbing?
