(see note at bottom of post for update)
and one really is none.
I have this generator that I built years ago. it uses a Lister CS clone as the prime mover with a belted generator head. It will generate 10,000watts (continuous) up to 14K for a short period of time…..It will burn almost any liquid fuel, from Kerosene up to fairly heavy fuel oil…(so long as it is liquid). It preheats it’s own fuel, and is an easy to service, reliable, very efficient setup. On diesel, at 5,000 watts, it burns less than a half gallon per hour
So I start it several times a year so I know it will be available when I need it. This year, I did my usual, drained the water from the fuel tanks (condensation, you know), oiled the spots that needed oiling, cranked it up (hand crank…takes a bit of effort) and away it went. Ran it on the startup tank (kerosene) then switched it to the main fuel tank…..
I noticed that the fuel filter for the main tank was 4 years old (only about 10 hours, but still, 4 years) and went and found the spare filter (two is one, right?) I got sidetracked, and when I went back to the servicing of the genset, I decided to order another filter before removing the one that was on the engine, as there was no reason besides preventative measures to change it….
Now, when I built this genset, I chose a filter that also worked on another common piece of equipment….saving spares and all that. This other piece of equipment is a 750,000 BTU fuel oil heater..a giant torpedo heater. Both share the same filter because I engineered the genset to use the same filter…
Sadly for me, the filter is unavailable….the part number is Wix 24104…which Wix has discontinued. It is also discontinued by Baldwin, and FleetGuard, and Luber-finer, Donaldson and apparently everyone…I cannot find a cross reference that is available…….It is (was) used by many large heater companies, but they are Unobtanium now….
I only had one spare. Now I am unsure what I am gonna do…I can easily find another filter and filter head mount to replace the one on the genset, but since (apparently) no one makes them at all, I am not sure what I am gonna do for the heater….(They don’t need to be changed often, but when they are clogged, they are needed very badly….or the unit will not work)
This isn’t a “supply chain” issue, this is the industry choosing to discontinue a filter across all manufacturers. Wix purges their dimensional data when they discontinue a part, so I am not sure if I will be able to find another compatible part number…(Lots of filters use the same threads and gasket dimensions, just slightly different media or flow rates).
A lesson I thought I’d share. Low consumption items , but critical ones, can be an issue in critical equipment…..Have more spares.
Without the filters, both pieces of equipment will become useless.
2 is…none ….if you cannot get a replacement and right now…I can’t.
(Many thanks to Reader “D” who found a compatible filter and who led me to a ready supply. The internet community can be a wonderful place sometimes. )
