So I am wondering about my fuel water separators. I have the clear plastic drain bowls on the bottom which are black so I have been trying to loosen them for cleaning and after soaking with penetrating oil for weeks I now have them both loose. But so it now dawns on me, now what? If I drop the bowls for cleaning does the fuel come gushing out? And what is inside the large black housing the bowls are attached to? Also what are the odds that they would need new o rings? Anyone replace these units with newer versions and if so what are they. 

Thanks
Brad

Brad,

Would you post a picture of what you have?

my 90 had two of them. one for each tank. once i took them apart it was hard to get them to stop leaking. they are old, brittle, and totally not able to get parts for. (other than pitcock). even that was hard to get to stop leaking.

so just be careful.

Just my opinion, get rid of them!  I’ve had great success with Racor’s filter/separators.  A quick search found this site: https://www.jmesales.com/racor-turbine-s...-unf-2010/.   Search around for the best price.  This one is 10 micron and that is determined by the element installed.  The generator won’t need one that large and several are listed on amazon’s site.  Your silver 92 has two filters and after using a filter such as this, you’ll find it unnecessary to change them as often.  You might want to opt for a 30 or even 60 micron but you’ll change engine filters more often.   Cummins Fleetguard offers much the same product.  Even the Davco filters used on the newer series 60 engines would be a good choice.

These are easy to replace the filters and there are options for heaters and water in fuel probes.

So will the fuel come rushing out if I drop the bowl or even remove the fuel line? This could cause air in the line.

So has anyone ever changed out these filters?

[bestgenman]

I have changed them out on #188.  Yes, the fuel will come out when the line is removed however,  it is a siphon situation so if you raise the line above the tank the fuel will stop.  You will notice from the picture, there is a ball valve on the inlet to prevent fuel flow when the filter is open during canister changes.  Also note the outlet elbow is tapped to feed a small lift pump which had the discharge ending in a ball valve.  Energizing the pump allowed spin on filters to be filled.

Thanks Gordon.
Seems best to expect a bit of a mess initially, adding a ball vale to be able to shut off would be a good idea.
