Drain Water Seperator

[kokowawa]

I have Ford F350 dulley the Drain Water Seperator light keep coming on my dash i tried everything i did read here and on other webs

1- I did Drain Water Seperator but the light came back on
2- Changed the Fuel filters but the light came back on
3- Dropped the tank and cleaned it frash fuel but the dam light came back on

each time after 10-15 miles light is back on

when i open the drain Fuel come out i think it has water and really sometimes i don't see anything
what else can be done
2008 Ford F350 with 71k miles

Take apart the housing on the frame mounted filter and clean it. It gets gunked up and will give false light. You will need a new gasket as well. Its easy to do.

Really easy to do I bet that's your problem. Sometimes the sensor itself just goes and it keeps saying that. At least now you have a clean tank. Out of curiosity how did your tank look

Common problem. If you keep your system maintained and it sounds like you do.....I'm betting the sensor is bad.

Yes, get the kit to replace the gasket and other parts on the side of the low pressure pump (under the truck). Remove the cover on the side (it contains the yellow drain lever) and clean it out. It's probably pretty gunked up. That will usually trip the sensor.

Worst case, you'll need a new sensor.

but it does drain each time i open the lever
is that what should happen

Yes, every time you open that lever fuel or water or both should come out. And the flow should be enough to fill a 20 oz bottle in less than a minute... more like 30 seconds.

You should drain it into a clear container (like a plastic bottle) and check it for water. The water will separate from the diesel if you just let it sit for a little bit.

Mine has NEVER flowed that much. Not even close.
