My fuel leak had similar symptoms - it ended up being the o ring inside and/or behind the water drain valve - the dealer tried to sell only the entire filter assembly - finally found a guy in parts that located the plastic valve and o ring separately from the filter assembly 40$ +/- new o rings in the old plastic valve may have worked tooNow my cummins performance big line kit is leaking at the psi port - new install and I used yellow thread seal on the pipe fitting - I think I was too tentative in tightening the fitting as it looked thin on the elbow where they drilled and tapped the 90 for the 1/8 mpt port - I will pull it apart tomorrow, re apply thread seal and tighten 'er down a bit more

I have utilized black PE pipe - (polyethylene pipe) to sleeve both fuel lines and 00 electrical going to a battery bank in the bed - this has been great to protect from both oil and abrasion - case in point - I lost my front driveline on my 2001 4x4 while climbing 8% grade pulling a car hauler in the winter - the driveline wreaked havoc - took out the tailpiece that the Tcase mounts to (but not the Tcase - WHEW!) and completely crushed and crimped the stock lines that were disconnected but left in place when I installed the Raptor - the new "sleeved lines that ran alongside the stock lines were completely fine - The black PE pipe is the same stuff that is used for Water Wells and Irrigation - Home Depot or Lowes - dirt cheap and will protect your investment - I believe I used 1" pipe the 3/4" will look like it will work but when you try to push 10' of hose through it there is too much friction - I ran the sleeve almost all the way to the stock filter Finally, if you route the hose with too tight of a radius, it will kink - heat will help to make it more pliable and easier too route - be careful with the heat gun or torchJ
