Water in diesel - If it should happen

[Logthumper]

I got water in fuel one time. The water separator caught it in time. If you pull the tank drain plug (if you have one) you will have a mess, and the receptaple for the drain plug probably has a short sleeve protruding up inside the tank (for the drain plug to thread into) which will trap a good amount of the water inside the tank. Instead, tilt the RV so that the fill port side is lower. This will allow the water to collect on the lower side of the tank. Insert a curved 1/4' or 3/8" bendable copper tube thru the fuel fill port until it reaches the bottom of this low side in the tank. Connect a short piece of flexible hose to the end of the copper tube and start the siphoning process. Siphon out the water until fuel starts to come out. Any water left (in any) in the tank will be taken care of by the water separator filter.

IF I was running a diesel and IF I was really worried about water in the fuel, I would install a push drain in the bottomm of tank and drain the water from the bottom. The Air Force drains it's aircraft fuel tanks this way, works well since the water settles to the bottom.

Boat supplies sell a water absorbing sponge.It only attracts water and not fuel.Tie it to a string or wire and drop to bottom of tank.It wills soak up any water present.
