    Hi Karl, probably should be able to work out what's going on, send me a PM with the make of the system and the symptoms of it not working and I will do some investigating, can ask the LPG guy that recommended my kit and is going to set it up when it's installed, so a good chance we can get it working.

    Couple of shots from the Scilly isles,

    Yacht Sapphire in Sutton Harbour dock, Plymouth.

    20180625_143059.jpg

    First sight of land, well of the Scilly isles anyway.

    20180625_215155.jpg

    Very busy in St Mary's harbour, double rafted to swinging moorings.

    20180625_204456.jpg

    Great light in the Scillys, well worth a visit.

    Back to LPG conversions now I am afraid!

    Filler point now fitted, a bit skew but I will adjust it when I fit the pipe.

    I have been trying to clean out the expansion bottle, tried in the dishwasher with limited success, now it has a dishwasher tablet soaking in it.

    20180702_125333.jpg

    Air filter cover rubbed down and repainted with red oxide.

    I have removed the inlet now in order to drill holes for the LPG jets, gave a good chance to look down at the inlet valves, they are amazingly clean, the advantage of indirect injection, either it is because I have been using Shell fuel, or more likely the huge amount of fuel that is sprayed down the ports!

    20180702_125609.jpg

    Inlet off.

    20180702_125553.jpg

    Nice clean ports.

    20180702_125505.jpg

    I want to recommision the air con, I cut the a/c belt off a while back as the tensioner was noisey, priced up a new tensioner and it is very expensive, so I took it off and had a look, luckily it just has a normal bearing in so I will be able to change the bearing for about £5.

    20180702_164454.jpg

    A 6301DU bearing should do the trick.

    I have ordered lots of other bits for various repairs around the engine too. Even new spark plugs!

    Unfortunately the intake manifold gaskets probably won't be able to be re used as there is corrosion on the main one, I have ordered a new but it will take a while to get here, I should have ordered it in advance really.

    I put a hand full of small gravel in my expansion tank with soapy water. Pretend your making a cocktail and itll be spotless in about 3 minutes..

    Sounds good, can I use mojito and crushed ice instead of soapy water and gravel? :D

    Hot water, gravel, sharp sand, and about 10 mins of shaking!

    20180703_121236.jpg

    20180703_121246.jpg

    About as clean as I think I will be able to get it!

    Very quiet around here I think there is football going on.

    20180703_185359.jpg
    Inlet manifold drilled and tapped for Flash lube jets.

    20180703_185416.jpg

    The worst bit was the first drilling, as there was no way back!

    20180703_185623.jpg

    After some fiddling got the tubes to fit nicely. I wanted them concealed inside the inlet, not on show.

    20180703_185640.jpg

    Cable ties secure the small manifolds that supply the flash lube to each port.

    As you can see there is a lot going on in the gap between the 2 halves of the manifold, but it is relatively easy to separate them.

    20180703_185935.jpg

    This will be the route the Flash lube tube will go to get to the bulkhead. The vacuum tube for the map sensor will be routed the same way.

    20180703_183317.jpg

    The jets holes are drilled and tapped, then I used pipe seal to seal them.

    20180703_183332.jpg

    The flash lube jet position is not important, but should be at 90deg to the airflow to ensure Flash lube is drawn through.

    20180703_183306.jpg

    This is one of the LPG jets, they must be fitted as close as possible to the petrol injectors, this is to ensure good idle, fast switchover with no stalling between petrol/gas, and to get the injection timing more accurate for efficiency.

    They have to be at 90deg or less, they don't have to point at the back of the valves like petrol injectors, as the gas will not condensate on the inlet walls like petrol will.

    20180703_185504.jpg

    This is where I plan to fit the LPG jets, that is as close as I can get whilst still being able to access the bolts that hold the inlet on. I don't want to fit them underneath as oil or dirt could collect in them.

    They are M10 x 1.0 which I didn't realise I don't have a tap for, so I have had to order one.

    The LPG fitter I got the kit from said normally the jets are drilled without taking the manifold off, using a special drill with a hoover on and a tap covered in grease. I imagine you would get your jets fitted wherever the drill can reach. I didn't fancy that idea...

    I dont blame you Rich that sounds risky. Looks like a very long winded and complex job. Well done for sticking at it

    Bracket for the gas filters cut and tacked.

    20180704_204000.jpg

    More offcuts of stainless I am stretching them a long way!

    20180704_203935.jpg

    I need to cut slots to let the pipes through, and there will be a stay up to another bolt hole to stop it flapping.

    20180704_203927.jpg

    Next job check it fits and clears the coolant pipes, then cut slots and drill for the filters, complete the welding.

    20180704_204707.jpg

    These are the mechanno brackets you get to mount the gas filters, ok but they could vibrate, I will ignore that you could probably build a house of cards on a running 1FZ-FE!

    Whilst fiddling around trying to think of somewhere to mount the injectors, realised I had the jets for the LPG the wrong way round! 20180704_222517.jpg

    The little M6 ones are actually the ones that go in the manifold, not the big M10 ones...

    20180704_222536.jpg

    Never been so glad not to have a complete set of taps in my life, otherwise I would have 6 great big holes in my inlet... narrowly escaped a major F up there!

    20180704_222546.jpg

    Good news is I do actually have the correct tap for the jets now, and also shortly receiving a M10 x 1.0 tap which can probably go rusty in my toolbox drawer.

    The fuel filter mounting didn't fit, the wiring harness is in the way.

    20180705_220844.jpg

    Made a Beta version. Should be easier to access as well.

    20180705_220850.jpg

    20180705_220857.jpg

    Made the brackets for the gas injectors,

    20180705_220927.jpg

    2 sets of these, they have to be unequal length to fit as the mountings are not on the same plane.

    20180705_220913.jpg

    Hoping these will look neat as I can run the pipes direct to the jets, and the wiring can go along the main harness and then out to the gas injectors.

    LPG jets fitted.

    20180707_101731.jpg

    20180707_101745.jpg

    Just waiting on manifold gaskets now but will do a trial fit.

    20180707_151424.jpg

    6301 DU bearing for the air con tensioner arrived, shame it is only sealed on one side!

    That would be why the original was a 6301 DU2... It will do for now though.

    New A/C reciever/dryer, Denso one from Opie oils.

    You're doing an excellent job on the lpg installation Rich.

    Good to see and thanks for sharing your experience! :thumbup:

    Thanks for the encouragement, I need it too as it is taking a lot more work than I thought. I am very tempted to spur off and do some more work on the roof rack, or the pull out kitchen I want to build in the back but I need to stay focused!

    Absolutely mate! I was in a similar position when I took my transmission into bits. The thing that gave me the drive was that if I didn't get it done then... I wouldn't get the use out of it!

    I've enjoyed the use of the truck immensely since!:icon-biggrin::thumbup:

    Did some quick calculations and I have saved £170 on petrol by using the MR2 rather than the cruiser, that's just for my commute to work for the last month 16 miles away Ha ha.
