Which Toyota Hilux models are indirect injection diesels?

[NS_Albury]

I am wanting to buy a diesel Toyota ute and am having trouble finding detail for each model as to the type of injection it has. I am looking at older models (1980-2000) 4X2 dual or extra cab and preferably automatic - I realise that's tricky! (Impossible?)
I am wanting a vehicle I can simply filter WVO for and use without thinning with additives.
Does anyone know where I can find a guide on exactly what type of injection each diesel Hilux has?
Thanks : )
