I hate to bring this up on the TDRweb site but here goes. My friend has asked me to try and change his fuel filter on his 02 duromax 6. 6 Is there any thing I need to know about the filter change, I can see a wire running from the filter to a wiring harness and it look's pretty strait forward as for as a filter change any help short of asking him to buy a dodge would be appreciated Thanks Don
