Where’s the RACOR?
On some of the 2001-2003 Marathon
conversions that I see online I don’t see the long RACOR fuel filter
that I see on some other conversions. I’m generally looking on the
right side of the engine bay. Is it located elsewhere or just not installed? If there is no RACOR installed is that something to be
concerned about? -

Tim,
Not sure if this was an add on by most converters or if this was a standard option by Prevost. if it’s not a standard option then it may be that the converter didnt put it on some of their coaches. The fuel system from Prevost will have a fuel filter, maybe just not a Raycor, servicible one. You can always install one to get the benefits of being able to service it.

Not necessary. Neither of my coaches have had one. I would not worry about it.

Mark, that may be true, but on my previous Liberty, we picked up some bad fuel out West, and that easy-to-change, easy-to-clean Racor was a lifesaver. I have never seen a big boat without multiple Racors, and I believe our fuel cleanliness and serviceability is just as critical as it is on a boat. Just one man’s opinion.

Racor here from the get go.

Tim,
Here’s an answer from a Marathon owner with a 2002, the vintage range you asked about. We have the spin on with site glass instead of the Raycor.

I agree with Mark to an extent. I had two coaches with one, and now one without.
I always fuel at high volume stops and my fuel is in good shape regarding water or algae so my two conventional filters are adequate, but there is a lot of comfort knowing a Racor used as a primary with a 30 micron element was really great because I had a visual on sediment or water. I am not hung up on Racor, but I do like a filter with some provision for a visual inspection. I miss that but it would never be a deal breaker. there are a lot of other far greater wants and needs.

There is nothing wrong with a Racor filter. I know lots of people who use them. We did not have them on any of our trucks, nor have I had any on my two coaches. In about 110,000 miles of coach use, I have not had any issues with fuel, so having a Racor would not have done anything for me. The two spin on filters are all that Detroit specified, so they must not think additional filtering is required. My primary filter does have a drain cock, so if you are worried about water, you can check for it. I never have, and at filter change time we have never found any water in it.
The fuel we get today at high volume stations is so much better than it was 20 or 30 years ago. Water is almost never an issue now that everyone is using tank monitoring equipment that tells them if there is any water in the tanks. The biggest issue I can think of is the stupid requirement for bio-diesel, and that won’t be fixed by a filter.
You are correct that a marine environment is worse, and there may be a good reason to have a Racor or two.
