Hi felix,

I'm no expert on other models but I know my own vehicle well. I choose to keep my older 4x4 HJ45 Troopy because it suits it's purpose well and never let me down.

In the bush it's often my old troopy that helps out the newer flash shopping trollies when they break down or get bogged up to the doors in mud holes.

The inline nippondenso [clone] ip's are tough units and would seem to be the ip of choice for wvo. The "H" series of Toyota motors do not have a return to tank fuel line from the factory because thats the way they were designed. This is handy for those of us who choose to convert these engines to wvo. We can use a manual 3 way ball valve/tap instead of the 6 way electonic pollak. There are also 3 way electric valves if you choose. Tim and Brian have gone one step further and made/designed a electric 3 way ball valve/tap themselves.

The answer to your question about the lube, cooling and pressure is not so relevent with the inline pumps. They were made to have high tolerances for the different tyes/quality of diesel fuels and conditions found around the world, where the vehicles were being marketed. You should read HC11's sticky at the top of the thread list for svo/wvo if you have not already.

The problem with newer diesel vehicles is they have engines and ip's designed more and more for higher fuel ecomomy, lower emissions and a new different standard of diesel fuel. These engines include more fuel sensors and electronic injection, ie/ new versions of common rail. These engines are going to be much harder and expensive to convert to run on wvo. If they can be converted at all.

If you are going to buy a vehicle to convert you don't need to buy a 4x4 or a antique, many vehicles are suitable for conversion. Read 98Troopy list of converted vehicles thread,

God bless froggo.
