6.5 TD Secondary Fuel Filter Install
For those that are worried about the qulity of fuel like me. I have just installed a secondary fuel filter/water seperator between the factory filter and Injector pump. The install was relatively easy and I was finished in less than two hours.
List of parts:
1 NAPA Fitler Housing #4770
1 NAPA filter #3674
8ft of hose
Brass bushings for barbed fittings
Brass barbed fittings
Barbed union (to join existing hose to new hose from OEM filter assembly)(NAPA didnt have in brass)
I mounted the filter on the drivers side of the fan shroud. It will need to be shimmed a 1/2 in for filter to fit properly. Shroud will need removed for this and is easily done. Removed fuel hose from fuel cutoff and slid union into oem hose. Installed new hose running to filter inlet side. Clamped all fittings. Ran hose from outlet of housing to barbed fitting on fuel cutoff. Before I hooked up to the IP, I cycled the key until fuel came out the end of the hose to prime it. Still had air in the line, but alot less than expected. Zip tie the hoses to the coolant hose leaving a little slack for engine twist.
Start truck, check for leaks, and enjoy a fuel system cleaned down to 2 micron.
Clean fuel will ensure longevity of both the IP and injectors.
