I have suffered from overheating fuel pump ever since I bought this truck and in fact I even installed a back up electrical fuel pump to switch between the two. Despite these every summer dealing with heat was a pain in the neck. Finally after a day of having to switch back and forth 5 times I came up with an idea which has worked so far. Idiotic as it may seem it might help others who have the same problem. So I share it:
First I changed the place of hose where fuel is sent to carburator. I tried to pass it through a cooler area insted of going right on top of engine which would be very hot. Then I found galvanized metal ducts (actually low teck chimney for fire place or oven) with two corresponding 90 degree elbows and put them together in manner shown in photos bellow. It is installed in a way that colder air from the bottom of the truck (when it moves) is pushed up to the fuel pump which has a sock full of wet sand sitting on top of it. A plastic water container with a robber hose is supplying water to the sand in the sock when I press its sides. This is done before I start a journey or if it is too hot once or twice during the day.
Finally I placed a bit of aluminum foil between the engine and fuel pump (till I find better insulation material).
It looks ridicuouls but since I have added this I had no vapour locking problem.
I welcome any suggestion for imporving my hillbilly solution (what is the equivalent of hillbilly in uk?)
regards
