Fuel filter install question
Well kind of, how do I depressurize the fuel system so I can install the fuel filter with the least omaount of fuel going every where. Truck is 92 F-350 with a 351W. I know on most vehicles there is a switch or at least a fuse to pull, so where do I begin.

I would recommend the night before take some penetrant and spray the two fuel filter connections. To relieve the fuel pressure, there is a valve on the left side of the engine bay (it looks like a tire valve on the fuel line). They sell tools for this or you could use the blunt end of an 1/8 drill bit. There should be very little fuel loss, the only loss will be from the filter itself.
