I dont believe so.The pressure inside the injectors is usually between 11000-20000 psi so I cant see the how a few extra pounds of pressure in the fuel line will help.

You want to run it as a 'lift pump' ? Then yes it will help as it places a small head of pressure onto the main pump, and reduces cavitation and starvation on the main pump and increases the efficiency of the main pump. Will it give a remarkable increase in power etc. can't say, but it can't hurt. Low pressure external fuel pumps aren't too expensive so it is a cheap experiment.

A lot of hydraulic systems ( oil / fuel / water etc) run multiple staged pumps, on the aircraft we even had pressurised storage tanks . Most race cars run lift pumps from the fuel cell to a surge tank, then through multiple pressure pumps to the fuel circuit.

Colin,
I have an electric pump on my Rangie, this is more about info for finding a fuel pump rather than the improvements you encounter. If you are looking for a pump Rangie parts suppliers sell them as a replacement for the super reliable diaphragm pump they had installed as original.
Things I would watch for is what you are pressurising after the fuel pump like the fuel filter and the fuel lines from the pump to the filter, they might leak with slight pressure. My GQ had an extra filter on it with a glass bowl water knock out, I don't think this would of taken the pressure.
When you go out in the bush it's also something else that could fail, your normal diesel pump won't be able to suck the fuel through one of these pumps if it breaks so you could end up in a worse situation. My thoughts.
