Proper size Racor

[George Dibble]

My 37.5 Hunter has a 3JH2E Yanmar on it. It uses a Racor 110 primary fuel filter. It was recently suggested to me that I should install a larger filter (such as a RACOR 24?). My question is: is the Racor 110 the proper size filter for that engine? I recognize that a larger filter has a larger capacity to trap more residue, but is it worth it to have a larger filter installed?Another question. In a recent response, you indicated that the 3JH is a "self bleeder". Is this because of the little hand driven fuel pump on it, or something else?

Wonder why?

George: I wonder why "they" would say such a thing. These filters are rated at 15 gph. Unless you are getting very dirtly fuel and not changing the filter on a regular basis why would you need to change your system.Have you had any problems? Another option would be to add an additional filter Racor 110 in the line and have a 30 micron filter in the first one and a smaller 2 or 10 micron filter in the second one.

Don't need bigger filter

Your engine uses .5-1 g/p/h, maybe 2 racked up? I have the dinkiest Racor on my 3GM30 works fine.

Transparent Bowl

I prefer a filter with a transparent bowl. You can then see immediately whether you have some sediment, water or just plain ugly fuel. I also had racor 110's which rusted on the inside.
