Very good I believe.

I have a 12H-T HJ61 Landcruiser with a Nippondenso pump. The 2H uses a similar pump and there are a number of successful conversions. See the thread titled "Vehicles converted and successfully running on WVO"

One advantage of these inline pumps is that they have a separate lift pump. This enables you to do a quicker purge by feeding diesel straight into the injection pump on start up and shut down. See the thread on "Using separate lift pump and IP for a quick purge" which is particularly relevant to the 12H-T with it's high return flow out the back of the pump, and less relevant to the 2H which has no return flow. However the idea still stands.

From what I understand, the vulnerable Lucas pumps are not common in Australia. The majority of diesels do not have them. If you've not got one of them, then probably whatever you do have will do okay. It's always an issue of viscosity and flow. How you achieve the required viscosity and flow to make the thing run is what we all are here to figure out.
