On the left hand corner of the instrument panel on my Ford F350 dually a fuel pump symbol with fuel drops to the left intermittently illuminates. I cannot find this symbol in my owners manual or in the aftermarket book I have. I am looking for the meaning of this symbol. Thanks

 

Welcome to the site..

Sounds like low fuel warning lamp.. What year is your 350?

 

It is a Water in Fuel indicator, as far as I can determine. Means likely there's too much water in the fuel filter. The diesel supplement owners manual shows how to clear this out.

 

On the fuel line, under the drivers seat on the frame.Take that 7mm plug out and drain it completely, maybe a half pint. Then take a can of throttle body cleaner, with the little red sprayer attached and clean it out. I use Q-tips to wipe it out after I spray it several times until it is clean again. It really gets nasty in there too. Replace the plug and you should be good to go. My truck had the same issues until a Ford mechanic told me how to fix it.
