My truck ('99) uses the P/N 4882423 fuel filter assembly. This is the one with the canister that drops off the bottom of the bracket, the fuel line banjo fittings are on top, and the fuel heater harness emerges from the top. I've been told that it is common for them to leak at the fuel heater harness & mine was no exception. In addition, I've been told that neither Dodge or Cummins supports this fuel filter any more, their recommendation being to update to the newer assembly. I was quoted almost $1500 by my local dealer for the repair - totally unacceptable!I disassembled the assembly (remove 3 torx screws, push heater assy/harness out) & found the leak was due to a degraded & damaged o-ring installed on the heater temp switch where it passes through the bracket. I took measurements & ordered a bag of o-rings from McMaster Carr. After clean-up & reassembly with the new o-ring, I'm happy to report the leak is fixed.I have 49 spare o-rings left. If anybody needs one send me a PM & I'll drop it in the mail to you.Joe in St Louis
