Here's a quick tutorial on how to drain water from your fuel filter (Fuel/Water Separator). The RV that we are demonstrating this on is a 1996 Monterey Beaver, Diesel Pusher.
This is something that should be done after each fuel fill up.
It is important to do this because a diesel engine fuel system relies on the diesel for lubrication, and if water gets in to a moving part, which requires constant lubrication, i.e. the injector valve, it will result in it overheating rather quickly and will cause unnecessary wear and tear.
Our fuel filter is located right on the side of the RV and I assume this is not the case with all RV's/Trucks, but you can see what it will look like in the video and if you crawl underneath and have a look around by the engine, you should find something very similar to ours. It will have a little screw plug at the bottom.
The engine needs to be warmed up to operating temperature before doing this (at least 140 degrees). Let it run for 10-15 min and it should be good.
Letting the fuel drain into a container that you can see through (glass jar or bowl), will make it easier to see whether or not there is water or any other contaminants in the diesel.
Ours looked good, but if there IS water in the fuel you'll be able to tell. It's kind of like oil and vinegar; the water separates from the fuel like oil separates from vinegar.
If there is water in the fuel, drain it until there is no more water.
If it's discolored (brown, black, contaminated looking), i recommend getting a new fuel filter all together.
You can find a fuel filter at a parts store like Auto Zone or even online in places like Amazon.

What a mess!!! Thanks for taking the time to show me what to do and what not to do. (-:
Warmed up to operating temp did nothing for draining water from the separator. It's fuel...
2 things.. Adding a good additive like stanodyne summer or winter blend depending on the season helps a lot. 2) if you are really worried about water, add a FASS type system. Not cheap, but works really well......
👌
why would you warm up the engine in order to drain some fuel ? doesn't make sense to me.
Yes, if you do any radiator work, you'll find that 'petcock' is the common name for the 'drain' valve. Hint: Use nitrile gloves when messing around with diesel fuel.
Thanks for posting. How do you dispose of the stuff in the jar (assuming it has some diesel in it)?
awesome! clean clear instructions! Saved me a trip and money from getting it serviced for this easy fix Thanks man!!
Don't have to fully remove the petcock just loosen till it starts draining
He needs more pot.
The way I dispose of the water that gets in the fuel is put it in your old used dirty engine oil and take it to auto zone
Entertaining and informative ;)
Nice Bro😎
Dude at 1:22 I see your WATER TEMP gauge...left side, next to tachometer. I can see it says 160, 180, 200....operating temp should about 185-190 deg F. Excessive idling isn't good for these engines. I have a '96 Safari Serengeti 38' Cat 3126 Allision 6 spd coach....but yours is the ONLY video I've seen with regards to the fuel separation filter.....kudos! I have a somewhat more elaborate filter/water separator, but essentially the function is the same.
QuantumRift idling doesn't hurt any diesel engine dude lol
@@woodman1241 That is absolutely false. Cylinder washing via excessive idling is a significant issue with diesel engines
@@TheSonicendeavor ive been around tractors and trucks my entire life. Tractors idle alot. Some have over 14000 hours. No damage from idling lol
woodman1241 My Cummins iSL9 manual specifically addresses this issue stating:
Idle the engine 3 to 5 minutes at 1,000 rpm before operating with a load. No more than 5 minutes.
Do not operate the engine at idle for long periods
This can result in the following (these are well known and documented issues)
• Fuel dilution of the lubricating oil
• Carbon buildup in the cylinder
• Cylinder head valve sticking
• Reduced performance.
Excessive idling isn’t good for ANY engines you dummies. Seriously, the only dumb hicks you see leaning on their steering wheels or leaving their rigs on is because they are dumb hicks. Once an engine is warm it’s duty cycle includes mainly load and infrequent idling. There is and ignition switch that operates very easily to start and stop warm engine’s very easily. You’ll save a significant amount of pollution and resources which is a positive too. We all know of the damage that particulates do to young human bodies. Why would someone add to that for no useful reason.
Again, dumb hicks.
Lefty loosey, righty tighty 😊
Cool, good vid... Thanks!
Thank you!
Nice work, love it. All instructional vids should be this laid back and smooth
Let the girl do it. She sounds smarter
i wonder of he is that bad at music? Are the Mahoney's still on tour?
FOUR MINUTES!?
wow man thats cool man lets burn one man
DIY mechanics out there trying to learn something, skip this video, you’re welcome.
Lolololol!
Is that. A fake beard.
As far as it's possible you should try to rehearse your videos. Know exactly what you're going to say and what you're going to show. Otherwise it will look clumsy and amateurish. Watching you try to unscrew that cap was painful.
Must be a joke operatin temp for fuel filter??? And temp range wow you know nothing about engine and need more weed
