ow do i unclog a fuel line on a 2002 ford escape ?

So you know the fuel line is for sure clogged?If so where the line coming off the fuel pump module or the line that connects to the fuel pump module?

Fuel lines don't get clogged. It is only the components attached to it that can cause clogging. If the line is clogged, then it must be kinked or crimped, meaning replacement is necessary.
