    Sorry Tony and 83patrol, I did mean to write start and purge on straight diesel and then switch across to a blend with an extra filter installed.

    Hi Tony

    The 1HZ is actually INdirect injection, as written:

    "but for Paul's Toyota 1HZ, which is indirect injection but uses a rotary IP, I don't think that's advisable."

    I'd still steer clear of a single tank system due to the rotary pump.

    That's what I would do. The extra filter for the WVO / WVO blend should be plumbed in parallel (separate) to the stock filter.

    Re: looking at converting my 2002 Landcruiser with 1HZ engine to WVO

    Firstly thanks everyone for the help to date.

    Got the car running on WVO now. Ran 500km over the last week and can't notice any difference in performance and efficiency. It was a bit daunting the first time pressing the button to switch over to WVO, but after that I had a big smile on my face for the rest of the day.

    I have been starting on diesel on sub tank and then switching over to a 10% blend SVO with ULP after about 10 minutes of running and the temp gauge is showing normal operating temp. I have also been switching back to diesel around 10 minutes from where I am going to stop.

    I am yet to put a 2nd filter in, but did replace my fuel filter 2 days ago and it looked clean with no junk or noticeable contaminates. Any suggestions on the 2nd filter I should put in?

    I have 6 linked 220L blue drums that I am running my oil for settling and in the final drum have set up an internal tripod with a 1 micon filter sock before being decanted into 20L jerry cans for filling up the car. Doesn't look the best, but works well.

    Cheers
    Paul

    Re: looking at converting my 2002 Landcruiser with 1HZ engine to WVO

    2 weeks running on WVO blend with 10% ULP now, but I have had an issue yesterday and again today. I've travelled 1,100km on new fuel filter.

    After switching to the WVO tank it runs for around 15-20 minutes without issue, but then starts to feel like its lacking fuel. While running on the freeway it starts to lack power and almost splutters. I switch back over to diesel and after around 5 minutes it goes away.

    I put a glass jar of my filtered WVO in the fridge overnight to see if any fats dropped out, all clear this morning. Nothing on bottom of jar and nothing floating.

    I'm thinking some gunk in the WVO tank maybe??? or maybe the uptake filter in the WVO tank is starting to get blocked. Thinking its not the fuel filter as it goes away when running on diesel. Anyone got some thoughts or advice?

    I won't be able to drain and inspect tank until boxing day or maybe weekend.

    The Cause:
    Using veggie oil will kill off any 'diesel bug' in your fuel tank and the dead bug will go into the fuel filter (& strainer).
    If it has got to the fuel filter (I think that it has) then it will starve for fuel on veggie oil but be fine after it clears the veggie oil, and diesel being less viscous will pass they the filter much better, leading you to think the problem is in the veggie supply line, rather than the filter.

    Change the filter and performance will be restored. This may happen for a few more 1000s of km, but after that it will be a long time between filter changes.

    The Remedy:
    You are probably better to have a separate fuel filter for each fuel tank. If you have a strainer in the veggie tank, is it removable for cleaning? Otherwise remove it completely. You need to have good access to strainers and filters to clean / replace them. If you can get a second filter housing and filter the same as the OEM one, install that in the veggie oil fuel line. You only need to carry one type of fuel filter then. Performance should restore immediately on changing back to diesel. Choose a convenient place to replace the veggie filter and then continue your journey.

    What Tony said, and consider blowing compressed air from engine bay to veggie tank just to ensure itís clear.
    Not sure of your trucks design, but note you may have a one way valve somewhere along the line that wonít allow the compressed air through unless you remove it, but if so ensure it also isnít blocked both directions with crap.

    Thanks Tony and Harvey,

    replaced filter and running fine again.

    with my cruiser the valves are next to the fuel tanks with a single line from the back of the car to the engine bay. To install a separate filter on veg oil I will have to duplicate line from tank to engine bay or install filter between main tank and valve under the rear of the car. I will have to double check for room under car. It's not a problem to change out filter on side of road for me so I will just carry a spare with me all the time and hopefully the period between changes will increase soon.

    Cheers

    Paul,
    You should consider installing a new fuel line in 12 mm pipe for the veggie oil. This will significantly reduce friction losses for the oil on its way to the new fuel filter. You should be able to get 12mm plastic air line which does the job beautifully. Fittings are available to mate with the connections to the fuel tank and to the new fuel filter.
    Tim HJ-61 has added a 12 mm fuel line from the fuel tank to the engine bay for this purpose. Search his posts to find out more.

    What Tony says, new bigger fuel line for veg. Separate filter under bonnet. Try to get your vege filter as close as possible to the IP even if you have to relocate the diesel filter to the back of the engine bay. I redesigned my system many times and now have no unheated oil at all going into the IP when I swap to vege. Solenoid valve is connected to the heat exchanger so it heats up and the hose from it to the IP is only 15cm long.
