I just replaced the filter elements on our Perko's last month. I think that the Perko's are very good filters.
The part number for the element is: 0324001ELM.

I ordered them from http://www.marinepartssource.com. They are $12.41 ea.

Good Luck.

Agreed, but they are NOT filters; they are strainers. What's the difference? Coarseness. A strainer (about 30 micron) takes out 'bowling balls'; a filter (about 10 micron) takes out fine grit. Both are needed.

So all in all better to stay with the perko strainer separator or change out with a modern spin on?

I also changed out the threaded EXPENSIVE fuel filter.

The Perko sediment/water separators work well no reason to change to canister IMHO

Remember: Fuel Filters MUST be after the fuel pump outlet NOT on the suction side! (intake)

safe boating,

Dave,

I did not know that the filters had to be after the pump. What's the reason for this?

A previous owner of my boat added a spin on water separating filter before the pump but left the inline "can" filter near the carburetor. Sounds like I will need to move some things around...

Maestro, there is nothing wrong with your set up. The previous owner just took out the Perko and replaced with a spin on, as I have done. No problems.

The element should be a Perko 0324001ELM. This element measures 1.75" x 1.75". This is the filter in use in our OEM bronze filter housings.

Any feel for how often this filter element should be changed?

I have one of those Perko elements that I no longer need. I also have the brass filter if someone would want it.

That Perko STRAINER (not filter) element is good virtually forever; just pull it and clean it every decade or so.

Here's the deal: You want a coarse (about 30 micron) strainer ahead of the fuel pump, to protect it. But you want a fine (about 10 micron) filter after the pump to keep crap out of the carb. The Perko strainer is coarse enough to remove big stuff without clogging. If it were a fine filter (like 10 micron) it could clog and starve the fuel pump, which uses only a psi or so to move fuel. On th eother side of the pump it develops up to 7 psi, which can push fuel pass obstructions easier.
