2 questions about Diesel in U.S.A.

[Electronic M]

Some stations have diesel hoses on the same pump as the gas (usually in pickup truck country), some have the diesel pumps separated under a different awning (usually in places where big-rig semi-trucks are the main customers since those things are huge and hard to maneuver in a swarm of small cars), others don't carry diesel.

I've also seen places (usually rural) where only one pump is diesel...Some of those places also have a separate pump for kerosene and or heating oil.
