Rob,
Here is a link to the basic setup.

This is a 10 micron filter. Once you get the three part setup you can change filter micron size at any time. The three parts are the mounting base with two inlets, one outlet (For two tanks) the filter, and the fuel bowl.
There are some filters available without the drainable bowl at the bottom. I would not recommend these. The ability to drain and inspect the sediment/water/fuel is what makes these drain bowl types desirable. I have only refueled at one marina and wound up with way too much crud. Even when shuffling fuel in clean portable cans from gas station to the boat I am still amazed at the debris and water I get from the drain bowl.
Something else to consider. As Bob mentioned the filter should not be bilge mounted without the metal fuel bowl. I assume this is due to possible damage from being hit as in my boat or heat damage if mounted in an inboard installation.
I bought my boat used and it has the plastic bowl (which is quite durable) on the filter. The two different mounting locations that most filters are mounted on the CD-22 are down between the fuel tanks or up in the splash well mounted port or starboard, opposite of a swim step if you have one. My filter is mounted low just to the right of the port fuel tank. Just to the right of the filter is a bilge pump. When I bought the boat I thought, this is a better location as in out of sight, and with two big dogs always jumping in and out over the swim step = less chance of damage.
A few weeks back we had the boat out for a weekend camping trip. First outing of the spring. The bilge pump had run a few times to evac some water the dogs drug in. Anchored in a quite cove my wife points out a slight sheen of oil on the water behind the outboard. I dismissed it as a drip from the exhaust or engine cowling from the tipped up outboard.
On the return to the launch point about 8 miles away we are put-putting along on the kicker. I get a wiff of raw gas and kill the engine to investigate. I had to move some camping gear just to get at the bilge/filter area. I was shocked to find the filter dripping fuel. And a nice puddle around the bilge pump. I would rather deal with a sinking boat than have fuel dripping on the floor.
I killed all the electrics except the motor. I was trying to keep that bilge from kicking on. I later remembered it was hard wired to the battery... I sponged up all the fluid into a 5 gal bucket. Had the extinguisher ready. I decided that if it went poof I would just try to get away from it. (Extinguisher not much use) Put the wife in life jacket, put her and the dogs up front and had the front hatch open for escape and closed the cabin door. I drained the fuel bowl into a small container and found some maple sirup looking crud. The filter normally can only leak from one of the two seals. The one above the white filter and the o-ring above the bowl. As near as I could tell it was the o-ring leaking. I had an extra filter but wasn't inclined to change it out there as it would have resulted in more spilled fuel. When I did change it at the house it required the rubber strap wrench so I wouldn't have been able to change it anyway. I ended up wrapping the bowl with several layers of duct tape. This stopped the drip considerable. I had a small container that would fit under the filter to monitor the leak and drain as necessary into the five gal bucket. I switched to the main engine and the plan was to make a dash to the ramp. At warp drive I should be there in no time. Wrong again. I wasn't sure if the filter was clogged or drawing air thru the leaking seal. The main engine would not run above 2000 rpm. Long story short after a long tense cruise to the dock we made it. When I changed the filter the o-ring looked fine. I don't know if the failure was caused by fuel additives, ethanol which has just arrived in our area or a clogged filter pulling enough vacumee to make the seal leak? I would recommend that anyone with a filter in the bilge location carry a container that will fit under the filter in this situation. A container that will hold enough fuel can be hard to find as the filter base is close to the floor not allowing much room for the container to fit around the filter.
I remember reading another brat had a similar failure awhile back. The whole point to this story is I now realize that the mounting of the filter in the splashwell is a much better location. It is easier to service. If you have a leak it goes out the well drain. You can use the washdown or a bucket to flush if needed. I was going to flush the floor with water and pull the drain plug once I got up to speed. But when I couldn't get up to speed that idea vanished. Hope all this rambling helps...
Since I don't have any marine places close by I have to buy off the web. Needing a few racor replacement filters I stopped by a local car quest auto parts. I gave them the racor number and they said they could have them the next day. I looked at the computer and saw three prices List $65, our price $21 and sell price $36. I kindly told the guy I could get them cheaper on line. He asked with shipping I said yea, If I buy over $50 shipping is free. He said: How much? I said $25. He didn't hesitate a second to type in the sell price to $25 to make the sale. I bought two fuel filters and two outboard oil filters for $10 each. We were both happy!
