Vacuum diesel fluid?

[renegade99]

I can get it to siphon just fine. I just can’t get all the stuff out of the bottom once there’s no more fluid obviously the siphon quits.

empty all the fuel you can then use a pressure washer to clean tank, it will overflow the filler and ge most if not all the debry out, then siphon the water and let air dry for a few days or rig a blower to blow air into tank to speed the drying. Refill with clean filter and fuel with an aditive to help with any residual moisture.
