The better question is, why are gasoline engines shut off when refueling. The reason you shut off a gasoline engine while refueling is because the vapour that is released from gasoline is highly combustible (hence, how the engine works) and even a small spark (like that from a spark plug) can cause an explosion. Diesel fuel does not "ignite" like gasoline, but rather an explosion is caused by the fuel being compressed to a point that it explodes. This means that it is safe to run a diesel engine while the fuel tank is open. As with all engines, the majority of wear and tear on a diesel engine happens upon starting the engine, so avoiding that step can actually conserve fuel and preserve engine life.
Diesel engines can be difficult to restart, especially in extremely cold weather, and the diesel fuel will not perform properly if the engine and/or fuel cool down. In extremely cold climates, truck drivers leave their trucks at a low idle all night to prevent freezing.
depends on the kind of truck
The pickups won't.. the F650/F750 already use them.
Most 2007 GMC pickups have the 5.3L V-8. That is standard in the pickup but some of them have the 7.3L Cummins which is the diesel and can be upgraded when you buy new.
No, some are rated at 195 h.p.
Passenger vehicles, motor homes, fire trucks, and pickups towing small trailers.
Toyota does not currently appear to be selling any light pickups with diesel engines in Mexico.
Started with the 2005 models, 300, Magnum and pickups.
No, diesel engines run with lower rpms and which also causes them to have lower tempuratures. diesel engines in semi trucks get up to 1,000,000 miles in them with just simple rebuilds. gas engines are a disiaster with over 150,000 miles.

Depends on what the transmission is. Bear in mind that Cummins engines can be found in 3/4 ton Dodge pickups and semi trucks alike.
2 pickups
Silversun Pickups was created in 2003.
