Finally the solution to the problem of overheating of the pump and the gasoline tank in deloreans.
Many deloreans including mine have always had this problem of having the gas pump very hot when you make a long trip around Puerto Rico. And in some cases total failure.
The problem arises from the poor design of the delorean cooling system.
Especially the tubes that pass under the gas tank. These tubes are heated by the coolant that comes from the engine to the radiator, heating the tank, gasoline and the pump to temperatures too high for its proper functioning.
As a result you hear a loud buzzing inside the car (pump too hot) and the possibility of failure.
For some time I was looking for a solution to this problem, and finally found in home depot a type of tape that is used to insulate tubes in the air conditioning system of homes or businesses. (To see photos).
It is an aluminum tape with high density foam insulation.
Using my own delorean I did heat transfer tests with one of the cooling system tubes and found that the heat transfer is practically zero.
With my delorean engine running I put my hand on the coolant pipe with the insulation and felt no heat at all.
If my hand did not feel any heat the tanks of the deloreans either
