Trying to trace an air leak, I removed my fuel filter for the first time and tried to remove the water separator from the filter. It simply will not budge and I am afraid I will strip it to hell trying to get it off. I have a new one on order. When I tried to wrench it off, I could see fuel "squeezing" out from the plug housing the wires for the electronics, and when I prime the pump, fuel will drip out the petcock drain. I wanted to know how much pressure that primer pump is creating and if that would be inevitable even when I install the new water separator. I am a little pissed that the gorilla that owned my truck before me wrenched every single thing on this truck just to the point of stripping. I even had to take a wrench to my oil fill cap to get it off.
