Most vehicles today are no longer made with a drain facility therefore will have to use the fuel pump in the tank to pump fuel into a (couple of 5 gallon containers or more ) along with some small bore pipe to fit the tank outlet. allow fuel to settle then siphon fuel back into tank keep the siphon pipe off the bottom of container (this where the WATER will be along with the fine sand sediment)
if a diesel empty the water filter trap under diesel filter housing this illuminates a light on the dash.
