My leak was more noticeable when the tank was full or after driving around the city. My fix was the vent hose was rotted off at the tank entry. The vent hose goes from the filler neck (where you put in the gas) to the gas tank. The good news for you is this problem was recalled by Ford and should be fixed at no charge to you. The bad news for me was I found out about the recall after I fixed mine.
In the gas tank.
About 10-13 mpg
35
It depends on where the leak is but my first guess is that it is most likely a gas line that has rusted through.
It is located behind passenger side kick panel.
my 99 e250 with 5.4 gas engine has 2 upstream sensors and 1 down stream sensor.
the fule pump is in the gas tank in the 1993 ford tempo
no gas line in front,maybe the charcoal fuel recovery canister?
my ford e250, year 2000 with 4.2L gas engine, auto trans, gets 9.5 to 10 mpg on regular.
The 1993 Ford Explorer is designed to use " regular " unleaded , 87 octane
Gas or diesel?
One of the fuel injectors in the throttle body may be leaking.
