New units can be bought with any of the filters in them. Most commonly stocked 500's are with 2 mcn filters.
All new style 500 elements come with the needed spacer. Making one is simple, I believe the directions are on their web site.

"The engine supply fuel pump is plenty strong enough to prime the system after all it runs the system at full load "
That's great if you have an electric pump and separate switch to run it manually. But for many small craft, the only way to run the diesel pump is to crank the engine (mechanical diaphragm pump) and that can be a problem, since turning the pump is only possible when you crank the engine--and that's a great way to burn out the starter, which is only designed for shorter service.

No?

I have one of the Racor spin on series. 320,(oe 230, I forget right now) I belive. The elements are more expensive but the filter housing has a primeing pump to fil the bowl and bleed the system. It takes me all of 5 mins to bleed my engine from a very accessible filter near the tank.

So I should switch from 2m to 10m, in order to get more water seperation? I've been using the 2m all this time thinking that "duh... why run a worse filter?" These are pre filters before my engine mounted one.

No, The only engines I can think of that didn't have a priming pump were a series of Universals made in the late 80's just prior to the buy-out by Westerbeke. Every other engine has a way to bleed it.

wait, there are many sets of Cat 3116's out there that didn't have priming pumps fitted at installation. But I'm retrofitting these as I find them.

Racor Filtration

Thanks for all the good advice. I think I'll go ahead with the project and use a 500 series Racor. Hopefully I can match up any needed fittings from a variety of sources if necessary.

Pat... I have newer Universal 35B which came with a Racor 10 mcn installed upstream. I belive my instruction manual also calls for that. Are we saying that should be 30 mcn.?

Also, when u say change carefully, what do u mean other than filling with fuel, etc.?

Thanks.

10mcn is acceptable. 30mcn is preferred. I have a service bulletin from Universal somewhere with this statement.
The 500 can be changed by carefully removing the element and replacing it, making sure the housing is full of fuel to the top of the filter.

Racor filters, Walbro pumps, polishing systems info

I was also told that the fuel pumps from a Subaru (purchased from a wrecker) work very well and are very robust. This person had one running long term in their boat as a fuel scrubber pump
