1fz-fe dual fuel system question

[joshAUST]

Well, nearly a year later, an update, FWIW.
I've spent the last year driving the car, changing the fuel filter every 3 months or so and just driving it slow, with less acceleration.
I haven't yet replaced the tanks, but am in the process of ordering parts, as I am going to replace both the fuel pumps, gaskets, etc.
I have found that you can rinse out a fuel filter, largely by blowing backwards through it, and a fair bit of crap came out, and then reused it once.
Not as good as a new filter, but might save someone in a difficult situation.

You've probably already replaced the fuel filter by now, but just in case, and for anyone else wondering, its very easy to replace the fuel filter.
On the output side of the filter, just squeeze the two white clips at the base of the hose and jiggle the hose up and it should disconnect.
Then, while holding the filter on the RH side with a socket, use another socket to loosen the fuel line nut.
Do not strip or damage that!
Then remove the two bolts holding the fuel filter bracket onto the chassis, then remove the filter.
Transfer the bracket to the new filter, finger tighten the fuel line bolt on loosely, then do up the two bolts, then tighten the fuel line bolt, then press on the output line until it clicks into place on the other end of the filter. Start the engine and test for leaks.

However, I have more serious problems.
The valves are burnt - according to a mechanic I took it to.
Requires the head to be overhauled, or replaced, with hardened valves if I want to continue using LPG as well as petrol.
I'm sure the PO must have been aware of it - that's a lesson to get a compression test done prior to purchase.

So, I think tanks installed first, then off to get the head rebuilt or replaced, and then I might do something about the hole/s in the exhaust....

Hope yours is going well @99fzj105.

Hi Josh thanks for your update! The last year has gone very quickly. I’m glad to hear your still sorting out your Landcruiser. Toyota do make great vehicles, unfortunately if previous owners do not keep up proper and regular servicing and maintenance that’s what let’s a Toyota down.

I have had a lot of work done on mine, it basically has not stopped since we last spoke. Someone said to me the other day, ‘that things gonna send you bankrupt’, I laughed and agreed. None the less it is running well. I have managed to get majority of the issues I previously had under control.

You should post some photos of your beast Josh so we can see her/him
