NH Workmaster 75
I got the error shown in the picture while bushhogging. Called NH dealer, they said it was a contaminated fuel error message. I drained water from the fuel/water separator, went back to work. About 45 minutes later error message back on. I tried draining separator again. Fuel level was less than ¼ tank, so I thought if I added clean new fuel it from a different source it would dilute the water (suspected contaminate) and would help, but it didn't, error message popped up again after running a few minutes. Tractor was running fine, no missing or lack of power.

Dealer says start by replacing fuel/water separator. My manual shows two fuel filters side by side and the manual instructions uses the word fuel filters. I understand that water is denser than diesel and will settle to the bottom of the tank. Should I replace both filters and try siphoning the bottom 5 gals of fuel from the tank? Or should I just drain the tank completely and

refill with fresh diesel after replacing the filters?

Thats what i would do…..empty tank. engine injector damage very expensive repair. I use a water filter system on my 55 gal bulk tank to try and help this issue myself.

I personally would also drain, and possibly flush the tank depending on what comes out.
I had a contaminated fuel issue last year in my Kubota that I fixed by running it low on fuel for several cycles and allowing a 2u Racor separator / filter to clean the fuel and tank up. It was more time consuming and expensive than just biting the bullet and draining the tank.

Unless you have a use for the possibly contaminated fuel I would "polish" it.
An Amazon knockoff Racor filter and a 12 volt pump and a bit of hose.
Starting out with a 10 micron filter and water trap, just draw from your tank and return to your tank.
Till no issues and good flow back with the 10 micron, then swap the filter for a 2 micron and repeat.

Thanks for the responses guys, I believe I will drain and flush the tank and replace the filters and see it that is sufficient.

Hello,
I run a non-alcohol additive 'Howes' in all my diesels, truck, tractor, excavator...it 'removes' water and is also a lubricant which is good for the pump, injectors..
