Manufacturers have had electronic pumps for years most were imports until early to mid 00s. Anything without a throttle cable has electronic control of some sort. Toyota had the 1kz and 5le of that Era. Some versions of nissans td27 are electronic as are the yd And zd. Mitsi have versions of 4m40 in import pajeros and 4m41.

OTAS HAVE A FAILING-ALAS RUBBER DIAPHRAGM IN PRIMER GUNGES -AND LEAKS DOWN-K Worse when lower on fuel.

No they are a mechanical pump with some electronics on them for crank sensor, timing, throttle position. The operation of the pump is mechanical so not common rail or HUEI or electronic injectors, so basically it can be a fuel problem or air problem in the fuel or pump.

thats splitting hairs a bit there.
we tend to call VE mechanical pump as all fueling control and timing is mechanical.
the electronic pumps get called efi, electronic etc. as fueling/timing is controlled electrically.
technically common rail, unit injectors etc are still mechanical, they all use a mechanical pump of some sort to generate the fuel pressure.
quite right it can be fuel or air and that was mentioned before.

HUEI injectors don't use a fuel pump to get the injection pressure so a little different to the norm. The electronic pumps are basically a mechanical pump with electronics added to them, it is possible to set them up to be used without the electronics.

That is basically the pump, a denso V3 resistor pump as on the 1KZ-TE engine.

Fitting a fall back valve in the fuel supply line side is a great addition to reducing air locks , Valve can be got from any diesel service center.
