Thank you Richard, has the Gems also the wasted spark ignition? In that case the LPG controller should already been set that way.
Not that I don't let it be tuned, but in that case I force it to drive on petrol when I go there.
That brings me to the next question, where to adapt the rev signal from on a Bosch.
The loom came from a Gems, below a pic of the connectors of the Gems ECM.
From the square black connector (white/purple wire) the rev signal was adapted, wherefrom can I take this signal on a Bosch system?
I have one unused connector in the LPG loom, according to the manual there should be connected something like this:
It also switches to gas when the engine reaches a certain rev (my next question for tomorrow), that should be a double input then.
Morning Richard, brass is the word. It is a bit difficult to find single spares for LPG over here, they all protect their business and want to do the job themselves.
Exept Vogels, they are friendly but 140 km away from me and their webshop is a bit unclear so I prefer going there in person.
They have brass nozzles and are AEB dealer, I need the inline cooling temp sensor anyway so after the weekend I will pay them a visit.
Have a good weekend.
Tony.

Right. I just have alu nozzles and was a bit exuberantly with Locktite, so the occasion I had to remove the middle ones they broke off.
(The middle ones cover the bolts of the manifold to head bolts)
Heat it and turn out the old thread, next nozzle will be bronze.
The walls are rather thin, be careful.
Chris my post crossed yours. Why do think I speak of "bananas" and "tubes" in multiple and not in "my banana" and "my tube" ha ha
Richard thanks for the scheme, first I will compare the colorcoded injectionwires of the loom I've got (Gems) with the ETM of the Gems and than see what colors the wires have on my engine (Thor) and find proof in the Thor ETM so I will not connect to the wrong wires.
Your remark on the Thor inlets being crossed confused me a bit, but I think you assumed I drilled the nozzles in the upper plenum. I drilled them right next to the petrol injectors to get the shortest route to the cylinders, I won't be fooled by a bunch of bananas, shiny or not (Marty!)
Marty, if you plan to go the "under banana route" there is no need to drill through the manifold since the 2 railtubes enter from the rear and the pressure controltube exits at front, that is if you have the same AEB injectorrails.
One item is missing I noticed, the coolant temp sensor, I'll give Vogels a call for a replacement
I think I only need to drill 2 holes per side, for cyl. 1 and 2 I can go along the front of the plenum and for 7 and 8 along the rear.
I measured the same length as when going through the bananawalls. Good idea!
About the clips you pointed at (good point Chris), my tubes are outside dia 12mm, I think I need larger ones?
Now I'm trying to find out what wire I have to interrupt from the petrol injectors, the loom I have is from a Gems and this is Bosch.
The drawings also state that the O2 sensors should not be connected (I found the wires though).
The guy from Vogels Autogas (supplier) I spoke to (helpful guy) said it was because the system should adjust itself too lean in case of a failure of the O2 sensor.
When I am finished he told me to give a ring to adjust the system (and report the authorities that the vehicle has basicly changed. If you don't report it is fraude of roadtax).
Normally they are only willing to report when they did the install.
Oh and you are excused about the shoes.
Richard I like your idea, just have to be careful not to puncture the bananawalls, so it is Dremeltime.
(and you didn't polish your shoes)
I'm in the process of installing LPG in my 2000 Bosch 4.6, first time so taking the steps one at the time.
I got this from a breaker as part of another deal, it came out of a totalled 4.6 Gems and the system is from 2011.
First off, where to put the injectors. I can place them on top of the plenum, they just fit under the hood as shown in the pic.
The bracket I made is not an example of fine craftmanship but it will do, the left rail has to raise over the steppermotor hose.
This is as close I can get to the inletnozzles when placed outside the plenum and will result in long tubes of about 12" , I have read not recommendable.
Another option is to place them under the bananaplenum, I can make strips to mount them to the same bolts as the petrol fuelrail.
This should result in inlet tubes of 2" max, all equal of length and a neat fit.
Disadvantage is a higher temperature and not being able to check the injectors and plugs without dismantling.
What do you guys advice? (More questions when things progress)
This is a satin black grille.
Zoom in and compare it to the headlamp wiper, it is in it's original colour.

Still cannot decide about the lower bumper where the fogs are.
Technique has improved.
In the sixties I've seen a guy plunging into a harbourdock with his giant Buick Electra, all he knew was he had to firmly pump the throttle while starting to let her fire up.
Then see to it it's not in reverse...
That's good to know, IMHO it's the same with tyres, softer tyres have better grip but wear faster.
For that price no argument!
No smoke over the Marlborough area yet?
We should have informed the local firestations...

Have fun, guys.
OldShep let's unite and hereby declare this thread as no-go area for this weekend for those left behind... :)
Oh yes I would love to, not even for doing repairs myself but lending a hand and getting drowned in P38 talk.
And for letting you pro's having a testride in mine to get advice in issues I cannot adress myself, like a rumble from underneath for what I think it's U-joints and someone else insist its the wheelbearings up front.
Or advice in what to put where in the transformation process to LPG.
Or hooking up a Nanocom to change my messagecentre from German into Dutch (motorhaube auf! with exclamation mark) only thing not in it's vocabulary is 'sieg heil'.
It even crossed my mind to ask if there was something ladylike in the Marlborough area so I could bring the missus, she's rather not even technically inclined for pushing brakepedals.
Oh well, maby there will come a next time so we can invade the Alexandra House and organise a weekends fun.
Tony.
I whish you all a happy wrenching weekend! Pity I can't attend, let us know how things get along.
I've got the Terrafirma too since a couple of months and am most satisfied.
The old one was shot, on a tarmac road it wandered always throug the 'tracks' if I may say so from side to side and that is history now.

The cap of the overflow bottle lifts at 1,5 bar from memory so your block is tight...

Speaking of law, over here fogs only may be on in combination with dipped beam, if you wire them combined with high beam you will have a problem using them in case of... fog!
Whether BeCM only monitors dipped beam is easy to check, unplug the extra high beams and switch on, no message no monitoring.
