the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work

Testimonial: "right answer but I received it much too late. I went to a mechanic and paid him to fix it."

It is most probably the crancase ventilator gizmo. Go to the Jeep dealer or other reputable mechanic to repair. I did and it cured the problem. It cost me about $120 and it was well worth it.

SOURCE: 1991 toyota 3L V6 Overfueling, raw fuel pouring out exhaust pipes

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.
