You are NOT gong to screw anything up. You actually put the Fumoto valve on the oil pan, after you drain the oil. Wipe it clean, make sure the last (original) crush washer is off the oil pan, put the valve in, with the new supplied crush washer, and tighten 1/8” after making contact with the oil pan. Easy Peasy.I was really tempted to try this. I guess since I have skid plates it’s probably fine. Just have anxiety about messing it up and then leaking oil all over. I guess I could keep the original in the truck in case shit ever hits the fan.
