Got a tank need to clean out so can weld tank sump & few other mods...the insides of tank covered in 2-3 mm sticky gum residue probably from fuel additives.
Filled it water then purged tank twice..lasted about a day before fume smell came back obviously cant weld it in case of a 'boomski'
Looks like crap you see on top of an old varajet carby except coated whole inside tank,never seen it one that bad.
Anyone ever had same issue?
Diesel,molasses or even vinegar worth a go?
