I have a 2001 Ford F-150 pickup. When I refueled it yesterday, I noticed a strong gasoline smell and an oily liquid (presumably gasoline) dripping down off the bottom of the fuel tank. Only a small amount had spilled (perhaps a few ounces) so I stopped fueling and drove the truck home. There is no evidence of anything leaking while the truck is parked.
this is probably a leak in either the fuel filler neck or the rubber hose that connects it to the fuel tank - not a leak in the tank itself or the fuel line;
it is relatively inexpensive to fix;
the vehicle is reasonably safe to drive in the meantime.
That seems plausible to me. Fuel leaking from the filler neck or rubber hose would drip down onto the top of the fuel tank and then eventually run down off the bottom of the tank. And the rubber hose in particular seems to be brittle to the touch.
Another suggested cause was overflow, but the dripping started well before the tank was full.
I would like to get a second opinion from this community as to the probable cause, and whether the vehicle can safely be driven.
