Before you start to clean out your fuel tank
check where the tank access is, usually through a pick up port.
Make sure the boat is securely moored, get some empty drums and fill with water
, place them on the deck
so that the boat is tilted (careened) and the diesel
tank access port is at the lowest point, leave for 2/3 hours to allow water/sediment to settle to the lowest part of the tank, then pump out the dirty fuel. Rinse/wash the interior
of the tank with paraffin (I use a garden spray) until clean. Remove water
drums from the deck
to level the boat again and refill with fresh clean diesel
. Change the fuel filters and the fine gauze filter in the lift
pump, bleed the engine and fire up. Clean the fuel tank/engine area and put some citron scented washing
up liquid in the bilge
to remove smell and emulsify any oily deposits. If any spots of oil
get spilt in the water alongside immediately give it a squirt of washing
up liquid to prevent contamination.
A wee tip, before filling with diesel, wet the deck before removing the the filler cap, if you spill any diesel it will sit on top of the water and not stain your deck, close the filler & give it a squirt of washing up liquid and rinse off for a clean deck with no diesel smell.
Now congratulate yourself with a nice cold one.
