How do you control the micron size of the engine mounted filter? I haven't heard of those listing the micron size or being available in different sizes.

If you have a 2 micron upstream, then why is the 30 micron necessary?

Re: Racor Filter element

Those engines like the Perkins 4-108 that have like CAV style system are easily removed and replaced with like a Racor 500.

But you can also get a screw on attachment for the CAV style's which converts your system into 'screw on' filters which helps with the mess. Still not as good as a 500, but it's better than the CAV style.

I'll never have a boat with CAV style filters again.

You could pour a little water in the filter and it would just sit there.
Trouble was the Baja filters were too slow to really use in the first place... with that in there it took forever!

The Baja filter later added a third screen that was similar to what you described. It was the bottom filter in line and was primarily the water trap. Fuel docks hate these thing since they really slow down the fill. Since we almost always jerry jug the fuel a siphon works just fine with this method. BUT if you get a large dose of water the Baja filter water trap element will fill up and still allow some water to slip by between the aluminum housing and inserts. After 15 years of using this method we switched to the West Marine plastic funnel type water trap. It's easier to clean and stow plus much lighter. You can also easily tip off the fuel left in the bottom versus the Baja filter which is messier.

Re: Racor Filter element

Rule of thumb, primary filter gets no less than 10 mic. Filter.
Secondary filter, 2 mic.
