This weekend I will try to install the NAPA 6637. I will also do an oil change and filter change. Also on the list is fuel filter, my question is which fuel filter to use a stock one or is there something better? I also would like to know who to get the SSHXO from? Thank in advance.

 

the stock fuel filter is good. for the high pressure crossover, go to www.itpdiesel.com
