Yes, I totally eliminated the FFM from the truck. Now this will be a warning to those who live in a colder climate where the fuel filter heater might be needed. the FFM has a built in heater element which you can also get aftermarket fuel heaters if needed. but since I live in Texas where it rarely ever gets cold enough to worry about, I went without it.
there are no issues disconnecting the heater and WIF connectors from the FFM and leaving them unplugged. there will be no lights on the dash.
I mounted a unit on the firewall and ran the hoses over top of the intake so there not in the valley in all the heat of the engine. it uses 3/8" hose so this also does the feed the beast mod as well. I did have to replace the fitting on the IP to accommodate the 3/8" hose too.
Here is the filter unit I installed. it has an extra threaded port if you wanted to add a WIF sensor and connect to the factory harness.
Here is te fitting I used on the IP. I did have to take my drill and open up the inside diameter of the fitting for better flow. but that was an easy thing. this fitting will thread into the filter screen on the IP for the DS4 pump.
I think I have a pic on my phone how I mounted mine. I will look and post here in a couple of minutes.
