And even then, it depends on the geometry of the system and how much airflow it takes to push water out the exhaust (there's still some air moving during cranking). Some systems are susceptible to flooding, others could crank all day with no issue.

Something to consider. My generator was stopping.... turns out, the exhaust elbow was about rusted shut.
My engine guru said, run it once a week and when setting it of a period of, flush with fresh water.
I know of one man who had his main engine exhaust elbow custom built of (SP?) monel upon the recommendation of his engine-guru

fuel Issue

Remove the fuel inlet line at the fuel pump on the engine.
Fuel should flow out.
If it doesn't then check tank level , system and all the above recommendations.
If you have fuel flow:
Remove fuel line at the outlet on mechanical pump on engine block turn over engine see if you have fuel.
If no fuel then the mechanical is bad . The diaphram usually dries up.

If you have fuel then bleed the filters on top then bleed the injector pump.

NOTE:
If there's no fuel to the pump eliminate the fuel system by attaching a separate fuel system using an outboard motor tank etc.
This could at least get you to the pump out.

3 or 4 books that occupy a book shelf and opened in desperation, something to read while waiting for help to arrive.

Yup, I was told, after three failed attempts to start the engine, drain the water from the muffler.

What is a "cav filter"?

Generally speaking, the RACOR is the first filter in line and then the primary/on the engine filter.
Where is the CVA filter?

Engine mounted filters on British engines; Ford Lehman, Perkins manufactured by CAV.

CAV Ltd, owned by Lucas, manufactures diesel injection equipment.

Off topic a bit, but can an older style electric pump be inserted ahead of the lift pump in a pinch if the lift pump has failed? Iím thinking an older Carter type pump that delivers 4-7 PSI and 50 GPH?

They don`t have to be engine mounted. Sometimes used as only filter, with drainable glass bowl.

I have a Walbro electric pump plumbed ahead of the lift pump to prime the engine and as a backup pump.

I do have it valved so the pump can be taken out of the flow when not needed.

How long since the CAV filter had been replaced? Be sure the Racor is the right size (yes there are different dimension Racors) and installed correctly.
