Reply To: Gas Tank Sealant

[green-thumbs]

It depends upon the type of tank…2 piece cast aluminum tanks (such as on Mercury KD3 are resealed by splitting the tank, cleaning up mating surfaces, cutting a gasket and applying a sealant/adhesive to gasket and
mating surfaces then fastening halves together (less all the details)
Other types of tanks can be made leak tight by use of what are called
“slosh & seal” which are liquids poured into a clean tank to form an inner
layer to seal seams and pin holes. There are also products applied to
exterior of tank
The cure varies depending upon the doctor , the patient and the hospital, . My patients have all been 2 piece cast aluminum tanks.

Model A Ford on line parts vendors offer a product to reseal the 11 gallon tank, so more than enough to do several outboard tanks. Those
with experience can say more about their experiec with slosh and seal.
