Cracked Racor bowl

Noticed a new slight fuel drip from one of my Racor filters so I removed the petcock thinking the problem was an o-ring at the bowl that needed replacement. I put on a new o-ring and after adding a small amount of fuel to check the seal the leak persisted. Thatís when I removed the bowl for a closer look and found it riddled with cracks and fractures at the threaded plug end. I would never have stopped the leak because fuel was leaking from the sides of the threaded end. The thought of a 900 series Racor blowing apart while underway is the kind of stuff that keeps me up at night. Four new bowls and parts are on the way, but there is just no end to the things one must inspect thoroughly on an older boat.

While you are in that neck of the woods might as well remove the Raycor take it to the work bench and rebuild it. Not a big job and it will be one and done.

I have two Raycors. One bowl is cloudy and hard to see through. Funny that the two Raycors are not identical, the bowls are different and not interchangeable.

Most solvents will cloud the Racor bowl and weaken it (don't ask me how I know). If you need to clean the bowl, use diesel fuel and a piece of cloth.

Huh. Never heard of a Racor bowl aging out.

Maybe it was an additive for the diesel fuel.
If mixed too strongly some additives may have had unintended effects.

Had one split completely up the side dumping all contents into the bilge until the fuel valve from the tank was closed. Ever since then I change them at 10 years and always carry a spare bowl in each size for every boat since. They are just plastic and I think the heat probably ages them out at a certain point.

An alternative. Easy changes. Never a leaking o-ring. No, you can't see through the metal filter but, then, the Racors are difficult anyway. Just drain a bit from the bottom occasionally and go boating. Sequential filtering, 20-micron to 10-micron. Except for the clear (sort of) bowl, I could never understand the fascination with Racor filter housings. Filters filter.Click image for larger version

Haven't ever seen filters like that with an installed drain. Where you get those?

Looks like the SMX brand from Seaboard Marine. Nice set up, and would take that over my Racors. Only drawback is not having the visual on the clear plastic bowls for water/contaminants.

Absolutely - that is what we changed to as well.

That crack probably is the result of somebody overtightening the petcock.

Nothing wrong with Racors. Clearly a superior product based on the quantities sold over the decades spanning all diesel applications (marine, generators, farming, earth moving, logging, over the road trucking, and other uses). Clearly the bowl isn't a problem in normal use as there hasn't been a recall on them.

It looks like it is on a Hatteras LRC. Those were made in the 70s. It could be an original bowl in which case it has given good service.

No, nothin wrong, but Racors need maintenance from time to time. Spin-on filter heads never. Takes five minutes per filter to change. No fuss, no muss. No clear bowl but an occasional inspection drain does just fine. Plus, those bowls over time become difficult to see through requiring disassembly and cleaning. Then there is the hokey, useless, metal "heat shield" required by the ABYC. The Tony Athens (Seaboard Marine) setup provides for sequential filtering all in a compact space. I had Racors, hated them. Messy to change filters (compared to spin-ons) and they don't filter any better or worse than the Fleetguards so out they went.

Thanks and good comments. I believe it would be easy to overtighten these and cause minor fractures that turn into cracks… and I agree these LRC bowls have seen good long service. If I have to replace the bowls every 44 years so be it. I won’t be around for the next swap out…

In 35 years of owning Racors on 4 different engines, I would say servicing them more than once every 10 years would be excessive.

As for changing the element, close the fuel valve, open the drain on the bowl, loosen the lid, and remove the element when it's finished draining. No mess, if you have the proper container to catch the fuel from the drain and a zip lock bag for the old element.

One of the other nice features over the Tony filter system, is that between the bowl contents and the filter element, you can see the amount of crud coming out of your fuel tanks. To see that useful information on a Tony system, you'd have to cut the first filter apart. Talk about a total mess for a useful piece of information!

Thanks, didn't know spin-on filters like those existed.
