How do I blow out (clean) the fuel line on a 1992 toyota camry 4cyl

If it ran for a few months after changing the fuel filter I would change it again and use a good fuel system cleaner. I would also use one that removes moisture from the tank.

I would check to see if you can hear the fuel pump humming when you turn the key before blowing out the lines. The fuel pump probably got too hot when you ran out of gas and now it's shot.
