rustykramermetalfab Posted January 27, 2023 Share Posted January 27, 2023 (edited) I have been searching for a relocation kit for the secondary fuel filter that is mounted direct on the engine. My ISC has them both in the rear hatch. The secondary would be a bugger to change out on the road. I suppose annual change is fine and I do all my own fluids but it sure is a pain. Just wondering if there is a kit to move it to a better spot. I have been searching but not finding a solution yet. 2006 Dynasty ISL 400. Edited January 27, 2023 by rustykramermetalfab more info added. Link to comment Share on other sites More sharing options...
Brad Kruchten Posted January 27, 2023 Share Posted January 27, 2023 I personally has not seen a kit. But, was looking at doing the same thing later this winter. Link to comment Share on other sites More sharing options...
Dr4Film Posted January 27, 2023 Share Posted January 27, 2023 I would also be interested if anyone finds a way to accomplish this task. After having an ISC-350 for 18+ years in my previous Windsor with both filters starring you in the face, I had to look all over for the secondary filter on my 06 Dynasty ISL-400. Frank McElroy had to give me it's location which I still have not put my eyes on it as yet. Every time I need to crawl under the coach my body says, "why are you trying to do that"? What a royal PITA! Link to comment Share on other sites More sharing options...
Georgia Mike Posted January 27, 2023 Share Posted January 27, 2023 I asked this question when I first got my Dynasty a year ago after I changed that filter on the engine. It is in a terrible location. Laying on your back you can only reach it with one arm no room for your second hand and just barely enough room to get a strap on it to loosen it. When you spin it off it is not a straight shot down you have to turn it sideways to manipulate it out so fuel spills all over you and you can’t prefill the new one for the same reason. I am getting ready to change it again so I bought a disposable bio hazard suit and long rubber gloves to try and stay dry this time. Also the little rubber o ring that goes on first was a loose fit and would drop off before I could get the filter up there a real PIA with one hand. So I am more than interested in finding a way to relocate it to the back or anywhere else for that matter. Link to comment Share on other sites More sharing options...
jegall Posted January 27, 2023 Share Posted January 27, 2023 I installed a FASS system kit comes with two filters easy install about 3 hours . Now my ISL 400 hp runs much better and easy starting with very clean fuel. 1 Link to comment Share on other sites More sharing options...
Dr4Film Posted January 27, 2023 Share Posted January 27, 2023 Did you eliminate the two stock filters by installing "dummy" filters in place of what was there? Link to comment Share on other sites More sharing options...

I put just a touch of light grease on the o-ring to hopefully hold it in place while blindly trying to find the threaded fitting. Link to comment Share on other sites More sharing options...
jegall Posted January 27, 2023 Share Posted January 27, 2023 I eliminated both filters and a leaking lift pump now 100% clean water and air free fuel . Link to comment Share on other sites More sharing options...

96 EVO Posted January 27, 2023 Share Posted January 27, 2023 Anyone have a picture of the factory mounting on the engine? Same side as the oil filter? Link to comment Share on other sites More sharing options...
Twomed Posted January 27, 2023 Share Posted January 27, 2023 Straight up above the starter. Good idea to wrap the terminals on starter with rubber electrical tape. After about the third time changing it gets pretty easy, still a stretch, but you know what's going on by feel...EYE PROTECTION!!! Link to comment Share on other sites More sharing options...
rustykramermetalfab Posted January 27, 2023 Author Share Posted January 27, 2023 Here is the photo. I am sure there are owners who have no idea this filter exists and probably a very neglected service item. Link to comment Share on other sites More sharing options...
96 EVO Posted January 27, 2023 Share Posted January 27, 2023 Thanks! Yeah, that looks like a PITA! Luckily for me, Cummins changed their design and eliminated engine mounted fuel filters before they built mine. Link to comment Share on other sites More sharing options...
Rick A Posted January 27, 2023 Share Posted January 27, 2023 I have a 2005 Diplomat. This post completely lost me. I have two fuel filters in the compartment where the air brake filter is. Is there another fuel filter lurking behind and above the starter? Link to comment Share on other sites More sharing options...

The FASS system comes with two filters one for water and one for trash the system constantly cleaning fuel and returning unused fuel back to tank . See picture the braided stainless hose is the supply to high pressure pump . Totally eliminating factory filters and leaking lift pump . FASS kit cost $650 and about 2 or 3 hours to install major engine improvement. Link to comment Share on other sites More sharing options...
Dr4Film Posted January 27, 2023 Share Posted January 27, 2023 So are the two factory filters that came with the engine completely bypassed and blocked off from the fuel delivery system? Link to comment Share on other sites More sharing options...

rustykramermetalfab Posted January 27, 2023 Author Share Posted January 27, 2023 Well Cummins is actually a customer of mine I have some contacts that I am going to see if they can shed light on this. If Monaco figured it out somehow they will never know, but I will make a few phone calls next week to see if I can get any help from them. 1 Link to comment Share on other sites More sharing options...
jacwjames Posted January 27, 2023 Share Posted January 27, 2023 I checked the Cummins Quickserve site for my engine and it shows the remote mounted fuel filter base and required hoses, this is for a 8.3 ISC. Not sure if the Quickserve site might show the different options for fuel filter mounting for an ISL but if someone does have and ISL with the remote mounted filters they should be able to provide the right information using the parts list. Here are my parts list for the remote mount. Fuel Filter Remote Mount.pdf Fuel Filer remote mount hoses.pdf Link to comment Share on other sites More sharing options...
Dr4Film Posted January 28, 2023 Share Posted January 28, 2023 18 hours ago, jegall said: Removed not needed. I assume that you rerouted the fuel hoses that went to the original primary and secondary fuel filters eliminating those two locations, is that correct?

jacwjames Posted January 28, 2023 Share Posted January 28, 2023 Richard, The Fass system I installed has two filters, the PF3001 which is 144 micron but the XWS-3002 is a 2 micron filter. So the filtering capability is better then what originally came on my rig and the benefit of positive pressure all the way back to the engine was the reason I chose to install one. I did leave the secondary filter base in place and use the original Fleetguard, I had extra filters on hand and figured just added precaution. Plus I added my pressure sensor here which tell me what pressure the CAPS pump is seeing. All the problems that I had been seeing with the ISC CAPS pumps pushed me to do the install. Time will tell if I did the right thing. Link to comment Share on other sites More sharing options...
birdshill123 Posted January 28, 2023 Share Posted January 28, 2023 Some of the filter mfrs. have kits to remote mount a filter. But in this case you probably need to build the kit. You may need longer hoses and some angle fittings to get the lines to the hatch. On our 08 both fuel filters are mounted in the hatch. No need to get underneath. Just reach in and your done.
