Where is the diesel filter located?
Most diesels have two fuel filters: a “primary” filter located between the fuel tank and the engine, which cleans the fuel before it gets to the fuel transfer pump; and a “secondary” filter up near the engine, which gives the fuel a final cleaning before it gets to the fuel injectors.
Why does my water in fuel light keep coming on?
First of all, you do not need to worry, this is a message indicating that the fuel water separator needs to be drained. After allowing the fuel to drain simply resecure the plug and clean up! Cycle the ignition key to the on position and wait 30 seconds before turning off and repeating.
How do you get water out of a diesel filter?
To drain water from your diesel filter water separator, release the vent valve positioned at the top of the filter housing. If there isn’t a valve, loosen the uppermost fuel pipe from the filter housing. Hold a jar under the drain plug or tap and loosen the plug or tap.
How does water affect diesel fuel and how is the water removed?
When diesel fuel contaminated with water is pumped from a fuel tank, the water leaves the tank as visible floating droplets which are relatively easy to remove from the fuel using a quality fuel/water separator.
What does water in fuel mean on diesel?
Water is a breeding ground for diesel-bug, but why is water in your fuel? It’s made up of the bacteria, yeasts and molds which the fuel absorbs from the air. The bugs attach themselves to the water droplets in your fuel and drop to the bottom of the tank where they feed from the fuel above.
How to drain the fuel bowl in a Cummins diesel?
Just drain the fuel bowl every fill up into a water bottle, take a look for water and say “oh gee there’s some water…” or “oh no water this time, yippy”. Or buy a kit like the TRC 2 Micron filter? Seems like Cummins really dropped the ball on this one.
Do you need to drain the diesel filter Bowl?
No need to drain the filter bowl with every fill up unless you have incredibly bad diesel. There’s a sensor at the bottom that will indicate if water builds up. I’ve never seen any water in the bowl when I change the filter every other oil change. I will say the filters do get pretty dirty so be sure to change them regularly.
Is the Cummins 6.7L engine still in production?
The engine continued in production until 2007 when it was retired for the 6.7L Cummins, primarily due to increased emissions regulations. The Cummins diesel engine is unique in the diesel truck world, as it is uses an inline design and only features 6 cylinders.
What are the problems with a Cummins 5.9 engine?
Despite the reliability of the Cummins 5.9, its fuel system is its Achilles heel. As discussed above, the fuel injectors are responsible for spraying highly pressurized fuel into the engines cylinders. With the 5.9’s fuel pumps flowing north of 25,000psi, the injectors face a significant amount of stress.
