The fuel filter on a 2001 Cummins can be replaced by loosening the nut on top of the canister, allowing it to fall into your hand. You can then drain the canister, refill it with fuel, and put it back on. Alternatively, you can screw the top off and pull the filter up and out, before putting a new one in and ensuring the o-ring is clean on the top of the canister. You can also get an aftermarket lift pump and fuel pressure gauge.
