What is this?

[2000CL713]

Not really sure what this does or how it works. Never had one like this on any of my trucks. Can someone explain how it works and whatnot? Not sure if it's some sort of fuel/water separator but its none of the styles I'm use to.

Thanks

Fuel/water separator with a screw-top bleed. State Patrol just called Barry, want to know who 2000CL713 is?  FUEL

Pretty color that fuel is..lol

You see, officer, my fuel is red because the bottom of the fuel tank is rusty.

Nice to know good try, now here is your ticket, pay at window 2.  Red is Red rust or not fines  based on capacity

The Officer: You see son them there fuel tanks are Aluminum and they ain't going to rust anytime soon, You say there's rust but I see RED die.

Boy your in a heep of trouble now, so bend over real slow now Ya hear... LOL!

It's a Con-Met fuel/water separator. Good performer and trouble-free. I used to spec them. No longer in production.

Well seeing as a got fuel a wawa last time I'm not sure why its that color lol 

How does this separator work exactly? Doesnt look like it comes apart or anything. Can someone go more into it?

[2000CL713]

Also can I delete this unit? Any reason to have it? 

[Maddog13407]

I usually pour a quart of atf in each fuel tank of my B at fuel ups...….. use to run red oil in a 2006 f360 6.0 I drove. damn thing could see a snowflake and gel up.....

The first stage of the fuel water separator uses a pleated paper element to change water particles into large enough droplets that will fall by gravity to a water sump at the bottom of the filter. The second stage is made of silicone-treated nylon that acts as a safety device to prevent small particles of water that avoid the first stage from passing into the engine.

Water and contaminants have a direct impact on the service life and performance of diesel engines. Besides being abrasive to engine components and cylinder walls, water and contamination displaces diesel fuel’s lubrication coating on the high precision injector components, causing tip erosion, surface pitting, fuel pressure loss and poor performance. If the separator fails, any water in the fuel can wear away lubricants on the diesel fuel injectors.

Unfortunately, there is no way to completely prevent water from contaminating fuel. Condensation is constantly forming inside fuel tanks year round plus most stations don't check their in ground tanks for water.

I regularly check the fuel water separator every third fuel up and open the valve on the bottom to drain the water from the water separator. IMO it's cheap insurance against issues and aside from checking and an occasional drain it's trouble free and no effect on performance.   Paul

Thanks for info. Reason why I asked is before I'm use to the newer types that are out today. Most have a filter or some sort. They are rather easy to understand. I have never used this type and wanted to make sure. 

None of my Mack's have a fuel water separators. Other then the 2 fuel filters. Never had a problem. 

Now the issue becomes how do I get parts for something that is no longer made lol would like to get a few sight glasses to have on hand incase they brake..... maybe there is a cheaper unit that would be a direct swap for this unit that I can still get parts for?

 

Again thanks for all the help guys!!

[41chevy]

Maybe KS can suggest who has parts.  Probably quicker and easier to replace with a "modern " one.  All my  equipment runs water separators because there is always that one chance of an issue that will cause an issue. I can't see losing a day or two and hours spent to fix something the unit would have prevented.  I also run accumulators to pre lube the engines on start up. All I can say is no major failures or issues. I go this way to add service life to my units.

KS?

kscarbel2      He was a Mack man from the best times and has a vast knowledge of parts, suppliers and people. He is THE person for that info.  The Autocar new truck post and most all the trucking news is his from his work association.   Paul

I reckon it will use centrifical force to separate the water etc from the fuel

Fuel floats on water so as it spins the water flow over the side and the fuel will run down 

 

Just a guess 

 

Like a centrifical oil filter 

Just clean and reassemble, last for ever and the engine oil stays spotless

His  and most here have a drain valve on the bottom the balance is sealed. Water molecules are bigger than fuel so the filter and mesh stops them and they settle in the drain cup, kind of like a moisture trap for a shop compressor.
