If it was a 5psi positive-displacement pump deadheading against a 100psi overpressure valve, you'd have problems, but most pumps are now turbine anyways.
Still can be an issue in certain cases, but I say drive it till it fails, then pull it. We know the failure mode anyways, and that the engine will run without it.
The original problem might not even be related to the fuel pump, it could be a weak return spring in the IP's banjo or a clogged fuel filter on the frame rail.
EDIT:
Just remembered the lift pump has check-valves, so you can still blow past it easily, I've pumped diesel through mine with a rattle-prattle inline pump before to purge air.

I can be wrong, don't take everything I say as verbatim, please fact-check first.
My posts are my personal opinions and thoughts, unless otherwise noted.
A surge tank takes care of it, and a high-psi pump against a low-psi over-pressure valve isn't much of a problem.
