Replacing the Racor Fuel/Water separator with Cat Filter

[Bill Borden]

This is an update with regards to The Racor Filter system change out to a Cat Fuel/Water separator discussion.
Thanks to Dave Atherton for supplying me with the part numbers for replacing the Racor system with Cat parts.

After ordering the Filter head, filter and water collection bowl from Cat, (it came with all O-rings and gaskets needed).  I designed and made an Aluminum bracket to mount the Filter head.

Then a trip to the Parker Hose and Fittings Store for the correct Fuel line connections and plugs etc. to marry with the fuel lines. Next assembly.

Priming, I primed the fuel system with the primary Cat primary filter bleeder.  With the Bleeder nut opened, I ran the starter motor from the back panel 3 times approximately 12 to 15 seconds each time, with about 45 seconds in between.
Closed the hex bleeder nut and she fired right up.  Ran great no leaks.

Next problem, the new filter setup was taller and hung down below, so I had a buddy make up a box, complete with a hole in the bottom to access the water collection bowl bleeder.

Road test, I put 500 miles on a trip to the mountains, the motor ran great, seems to be smoother and I am convinced there is added power along with an increase in fuel mileage.  I may be just wishing for the last part.

I always had a worried about the Racor system leaking air, I serviced it every year and checked it often. 
So far I am very happy with the changeover.  I believe it also simplified the fuel system.
 
I would have included a few pictures of the process; but I haven't figured out how to reduce the picture file in Win 10 to submit it within the size limitations.  Any suggestions there would be helpful. I will provide pictures to anyone that sends me a request.

The cost was about $120. for the project. Plus a nice bottle of Petite Sarah for my buddy who made me the box.

Thanks again to Dave and all the other Forum participants.  Reading the comments and discussion along with past successes gave me the confidence of completion of the job at hand.

Please feel free to contact me if you have any questions regarding this change over.

Bill, Looks as if you have had the same results as I did when we also converted as per Dave Atherton to the CAT fuel water separator. I did not however have to do anything other than remove Racor and drill two mounting holes. Had plenty of room. I also previously had changed the hose out per Daves direction so I was ready for the new filter system.
Had no trouble purging.
I have had coach out three times now for somewhere in the 600 mile range and it still runs smoother and quieter. Headed for 1200 miles to Black Hills this Saturday so we will look at fuel mileage to see if there is any difference on the plus side.
Lake Michigan Ferry ride for 4 hours from Ludington to Manitowoc should help that mileage situation tremendously. Wont help the pocket book however but gets you of the wheel for 8 hours. The 6 year old Grandson is also pumped about going on the Ferry.

Thanks to the information supplied by Steve and Joel, along with time to finally reading the instructions.

I have pictures to post of the installation.

Thanks again to Dave for his assistance.

After taking a few trips I am convinced that I did the right thing in changing out the Racor. 
If anyone is interested in the Racor unit I have all the parts in a box.

Thank you. Marty

Thank you Dave. Marty

[Bill Borden]

Dave and Marty,

My Cat dealer did not have in stock the fittings and plugs required, so I had to visit a Hydraulic & fuel line distributor, Parker had all the required fittings.

Everything is working great no leaks, more power, and better performance.

Thanks again Dave for helping me out with this change over.

I would like to install an electric fuel pump near the fuel tank at the front of the coach.
I need to know the requiered amount of flow to feed the c9 engine and where I should tap into the fuel line at the engine to install a presser gauge to find out if it is up to spec.
Can any one supply me with this info ?

[Doug Allman]
