I googled Alaska refinery and Google came up with:
Does Alaska refine its own oil?
Alaska has five operating refineries, with a combined processing capacity of about 164,000 barrels of crude oil per calendar day. Two of the refineries, in the Prudhoe Bay region, supply fuel for crude oil drilling operations.
In addition:
There are different types of fuel delivery trucks. There is what is referred to as a "Tank and Trailer" which is gravity fed for deliveries. They have minimal dividers and cannot deliver metered amounts. It just basically empties out whatever was loaded.
Then there are the compartmentalized trucks that are made for delivering to farm, construction sites etc... Divided to deliver on road/off road/ various grades of fuel etc.. They are made with a pump and meter to deliver as desired amounts. However these trucks usually only have high speed pumps.
Then there is a slower pump speed setup for "Fleet Filling" to deliver into gas tanks of vehicles. Often times a construction site or a fleet of busses, cement trucks etc.. can have a Fleet filling slow pumping truck come out and fuel each truck often times overnight. Saving trips to an onsite fuel tank or cardlock.
