Should be a flapper if its a 1988 unless its been swapped. Have you got an injector in the plenum, if so its a flapper

So you need a tank
a high pressure fuel pump
High pressure fuel lines presumably
An air flow meter
Relays
Anything else?

It may be easier to get a complete efi kit or complete range rover to rob parts from

There was only one Efi ecu for the 3.5 RR that was PRC6977, tune resistors are for the 3.9 hot-wire introduced with the 1990MY. I was there at the launch of the 3.9 but as my RR was only 18 months old the dealers didn't sell me one, but they tried.

That is a 1988-89MY 3.5 with the extra 'cold start' injector and it blue connector in the side of the plenum that 3.5s had, 1988 or 89 because some time around then the coolant fill tower was introduced, my 1987MY RR didn't have the fill tower.

Haven't a clue on that lump of round alloy is on the r/h side

Yes that's right. So it would be the flapper system.

No Tune Select Resistor because that came with the later hotwire airflow sensor.

My 1988 3.5EFI uses the ERC9127.

One source is SENSOR ASSY [ERC9127] - £399.62 : RJS Land Rover Spare Parts, Specialist suppliers of Land Rover parts for all Land Rover Vehicles but I dont know if they have it in stock.

Not cheap at £400+VAT but other places have it listed at twice that!

Or try our forum sponsors Emmotts of Colne
