Twin 50's Filter/Separator

I should have started a new thread instead of adding to a different topic altogether...so here goes. 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 a separate filter to each outboard and bypass the fuel switch.

Can someone advise the correct rigging...thank you.

Hi Vern,

I just bought a 22 with twin Honda 50s from EQ and they outfit it with a single fuel/water separator. I can grab the model number next time I'm at the boat if you're interested.

Also, both motors draw from a single tank, which I actually think is a good thing because then you can trim out the boat based on the fuel if you want, and if one tank drains before the other for some reason you aren't stuck with just one engine.
 
twin 50's should burn the same as a single 90 so one filter will work fine. I'd keep the tanks plumbed on the switch so you can choose which tank to run on.
 
There is a slight advantage of using two filters--one before the selector. That is, if the filter plugs up or gets water in it, you can just turn the selector switch and transfer to the other filter. This safety feature alone would lead me toward the separate filters.
