250ml
Overall it is about 20%
depending on how much petrol was in the tank and the length of the pipes it could take between 2 - 20 seconds before the engine stopped working

approx 1.7 oz
The density of petrol varies, depending on its composition. 20 thousand litres would weigh between 14200 kg and 15400 kg.
According to the 2011 Ford F-150 Owner Guide : With engine oil filter change : For the 3.7 liter V6 engine ( 6.0 U.S. quarts of 5W-20 engine oil ) For the 5.0 liter V8 engine ( 7.7 quarts of 5W-20 ) For the 6.2 liter V8 engine ( 7.0 quarts of 5W-20 ) For the 3.5 liter EcoBoost ( twin turbocharger ) V6 engine ( 6.0 quarts of 5W-30 )
I would recommend not running the engine until the fuel is drained. Any amount of petrol/gasoline in a diesel can cause engine or fuel system damage.
According to the 2008 Ford F-150 Owner Guide ( 5W-20 ) * with engine oil filter change The 4.2 liter V6 engine takes ( 6.0 U.S. quarts of 5W-20 engine oil ) The 4.6 liter V8 engine takes ( 6.0 U.S. quarts of 5W-20 engine oil ) The 5.4 liter V8 engine takes ( 7.0 U.S. quarts of 5W-20 engine oil )
There are about 20 vacuum lines. Do you mean a main intake manifold line?
i'll say less than 20 min.
A vehical that runs on petrol and diesel is impossible as they are both ignited in different ways. For exaple petrol is ignited by the spark plugs and a diesel is ignited by the shear force of the compression from the pistons. A petrol engine has a round 9:1 compression ratio and a diesel has about 20:1 but these veary from engine to engine I hope that hasn't lost you
