I have a dual by-pass remote filter mount that I installed, finding a suitable mounting place is much harder then it would appear. I have seen some use the single filter mount and install it in the area next to the alternator mount and battery hold down. I do not like that location or it's mounting device. The filter should be in a place that makes access easy, why mount it somewhere that makes service a real bummer? Also, if possible the mount should be in a spot that does not allow the heat to be given off under the hood. These trucks have way to much under hood temps already, we don't need to make it worse. And finally they should be protected from danger. That means they should NOT be mounted around moving suspension parts, or in areas that might sustain damage from road debra. Also, they should not hang down any lower then the bottom of the frame. The best areas would be ones that allow the filters both protection and access to moving air. Remote filters assemblies are serious business, the location you choose can mean the difference between a functional well working accessory and not making it home. Three easy rules I live by are 1. Function: it has to provide a meaning benefit, while not hurting other areas. Accessibility: Things are already cramped enough, do not make things worse with your addition. Security: It has to be well protected and securely mounted.
I mounted my filters in the right front corner, behind the bumper up next to the frame. It fits with all three of my rules and makes replacement a snap. I did have to work to get it mounted. I had to make room for the two large (AN #10) hoses, and I had to fabricate a mount. Also, do not forget to include the ideal of Insulation & Isolation into the plan. The mount will need to be Insulated from the frame, and the hose will need to be Isolated from anything metal or hard the length of the run. These diesels produce lots of noises and vibrations, this is transmitted through the hoses and will be a source of irritation if not carefully thought out. Good Luck with the project.
