And Vasco I think it’s unlikely to be the tandem pump. Although it has a test port on it to couple a gauge to if you have to.
I’ve never had to.
As before if the problem is fuel starvation as you suspect. You should investigate the function of the electrical pumps first.
Both pumps are powered I think from the same relay so they will run at the same time. So if you hear a pump humming when you activate them
It does not prove both pumps run. You have got to check. A pump that’s not spinning will restrict the flow from the other one.
I read the SSP years ago when I learned that pd engine did not need a high pressure pump.

Correct. PD engines have other 2 pumps one on the fuel tank and the tandem pump but none reaches the pressure to ignite diesel.
This high pressure is achieve at the unit injector which can rise the fuel pressure up to 2000 bar or even higher.
But the basics of compression ignition are that the high pressure system has always been there to over come effectively the high combustion chamber pressure at the correct time and with the correct volume of fuel.
