Truck is a 1997 7.3 auto. All stock. It is leaking fuel fairly badly out of the sensor on the pressure regulator on the bowl. Here is a picture for reference
My question is, what is this sensor? As it's not on my 1995 manual & can I just install a plug and forget about it? It is leaking near the base at the threads. Thanks for any info.
