The truck was traveling down the interstate with no issues when it suddenly died. When I took a look under the engine, there was fuel leaking from what looks to be the fuel pump or solenoid. The part that is leaking is just right of the main engine block and the accelerator linkage cable is connected to it. When I rev up the engine, using the linkage cable, the leak speeds up, then I let off it slows down. What could be the issue?

A petrol engine has spark plugs to fire the fuel and air mixture. When the spark occurs it starts a flame that travels outwards to the farthest reaches of the combustion chamber. The pressure on the piston rises progressively to a peak and as the piston is forced downwards the fuel is still burning and so the pressure remains almost constant for a time and then as the fuel is exhausted the pressure falls progressively.
Things in a petrol or gasoline engine happen fairly gently and progressively and the piston is pushed down.
A diesel engine is known as a compression ignition engine. It has no spark plugs to fire the fuel, instead it has a very high compression ratio that by the end of the compression stroke has produced a high pressure in such a very short time it has become a very hot and very dense atmosphere inside the combustion chamber. The speed of induction and the design causes the hot atmosphere to keep swirling.
Into this very hot place a very fine mist of diesel is sprayed at a very high pressure and the fuel droplets mix with the swirling air and heat up until each tiny droplet begins to burn almost simultaneously in every part of the combustion chamber, This, which is more of an explosion than a burning, causes the pressure to rise to a peak almost immediately and then reduce progressively as the piston is forced down.
Things in a diesel engine happen suddenly and rather than being pushed down the piston is kicked down quite violently.
It is for this reason the internal components of a diesel engine tend to be stronger and heavier.
The noise you refer to is known as "the diesel knock".
if thats a diesel inspec fuel injection pump for issues and also glow plugs--underhood chec for bad wiring--if gas engine then a tuneup cud be in order-new plug wires or coil/ign module--fuel pump may be failin
Have you replaced your fuel filter lately? that is usually the main cause for that common issue. A clogged or messy filter leads to starving the engine so when you accelerate there is a deficiency in the firing of the spark plugs. That then causes the jerking dying.
i had the same problem in a dodge ram pick up. ended up being the coil. when the coil got hot my truck would die or not start again until the engine had cooled down. replaced the coil, and whalaaaaah. no more trouble. good luck!!!!!!!!!!!!!!
