ford

#1

Leaks gas at top of tank when I fill up ,also what is the hose that gose from rear end to gas tank


#2

a few possibilities . . .

fuel filler hose/pipe is leaking . . . this is quite likely the case if fuel leaks as soon as you start filling up

fuel tank sender seal is leaking . . . this is quite likely the case if fuel leaks only when the tank is full
