Honda / Racor filter interchange?

A slight diversion here, but related to racor/honda clear bowl fuel filters mouted in the cock-pit against the transom; Is that they tend to take a wack once in a while, like from cockpit chairs and coolers. I have done some searching looking for wire or strapping to protect them from getting banged up but have been unsuccessful and thinking of fabricating. Wondered if anyone has improvised

I change mine every 100 hrs Racor#S3227(long version) a regular parts store (NAPA etc) will not be able to get these. A marine dealer only $25 bucko's here

warmed up to +10 this morning now if we can just get that sun to come back Mr. Green

I've seen photos on this site of a very neat installation where the person fabricated a shroud to protect the filter assembly. The assembly was mounted on the inside of their transom in the area above the rear drain plug and above the waterline. I think it was a regular contributor, but I can't remember whose boat it was. Very accessible, weather protected, impact protected. Someone else must remember which C-Brat it was... Mike.

I changed mine for the first time this fall. I was able to get the filter and bowl off without any trouble, however I had significant trouble getting the bowl off the filter. I could turn the bowl but that's all it would do is turn. It wouldn't come apart. I resorted to cutting the filter in half with a sawzall and using pliers to seperate the two.

I tend to overbuild stuff. In retrospect, the two pieces of angle are not needed. The rings are easily fabricated with 3/4in aluminum bars stock purcahased at Home Depot our your prefered hardware supplier. I just used a bench vise, a hammer, and a drill for the screw holes. I bent it around a paint can or something. I can't remember what I used.

I have tried searching in our library, but have not found if twin 50's (what I have) or 40's require two separate fuel filter/separators or just one adequately sized one? I have a Racor 120R-Rac-01 which shows max flow of 60GPH. According to Racor's general rule of thumb: h.p.x.36 = fuel flow (GPH). Since I have both tanks plumbed to the fuel switch, it goes to the one Racor. My mechanic is recommending that I go directly from one tank to filter to outboard and bypass the fuel switch.

Can someone advise...thank you.

Vern

I'm not sure why your mechanic want's to bypass the fuel switch. I like the choice of burning off one tank first if I need to balance weight ect. Anyway, I have a honda 90 running on one racor rt10 filter. Since the twin setup does not burn any more fuel than a single 90, it would be my uneducated guess that you can use one filter for both engines. Other than redundancy I don't see the point of having two.

flapbreaker-

My guess is that your mechanic wants to have a separate fuel tank and filter for each engine so that if the fuel from one becomes contaminated from age or a bad source, the other engine will still run.

With a single filter system, you lose the redundancy of having twins if a single filter or bad tank of gas can disable both engines.
