If I do that its looking like I'll need a second vent line. The pipe supplied is quite thick and with the wires Im gonna fall foul of cross area rule for the pipe. Seems I can't win

If you have 30mm Vent pipe (they also do a 26mm which is useless!) then by my quick calculations you are absolutely fine with the fill pipe and a wire :y

Well that sounds like the way to go then. It's easier to run a second vent than unpicking all the wiring if I get a tough inspection

Glad you've seen the light! We've got quite a bit of experience here now ;)

Make sure when you run the fuel line that you go around any potential pinch points... That Gixer fella is the expert on the route ;)

Well that's me stuffed. I can't get new nozzles for the injectors which fit the AC rail solenoids. I am out of ideas. I either go with the 2.5 which Cliff drilled the current nozzles out or I going to have to buy new injector rails. If I have to go down that route I'm gonna can the whole idea. Sick to death of it already and I haven't even got round to fitting the wretched thing.  >:( >:( >:(

I run TBE on AC rails, 2.5mm, and 1bar (when it was set about 18 months ago, not checked since...  ...in fact, I think I lent my cable out).

It "goes" fine. No probs whatsoever. But it doesn't idle well. Very grumpy at idle, unless in drive (or loads of electrical load).

So, I'd go ahead with what you have, and in parallel try to get nozzles from AC (or a supplier), knowing that what you have "works", just isn't ideal.  Mine has been like it for nearly 2 years...  ...I have the new nozzles, just need to do the work ;D

Also bear in mind that you could fill the old nozzles with solder or epoxy and re-drill them. It's not the end of the world. :y

That's an idea Kev. I've tried measuring the old jets across the threads to see what size I've got and it's 7 mm approx. My car normally always has the A/C I wonder if that would be enough to raise the idle enough to stop it burpin and fartin on tick over. I may wander out to garage now and try soldering the old jets to see what happens. Or I may pull the JD out the cupboard and sit here in a huff. Bad work day as well. hhmmmmm JD.

My A/C is always on. As you can imagine, this weather, the idle is particularly grumpy.

If I could find my lead, I'd set it to switch back to petrol under 800rpm, as occasionally it stalls. But then, I really should put the new nozzles in ;D

Right. I now have six nozzles with 2 mm holes  :) For those of you who are reading my "LPG versus JD" saga I did this the following way.

First things don't bother with a soldering iron. You need to get the nozzles hot. I found a plumbers blow lamp far more effective.
So take nozzle O ring off and gently hold with a pair of mole grips
Heat the nozzle. It doesn't need to be red hot. I did a mild count to 30.
Remove the flame. I found it easier this way.
Then just keep feeding the solder in to the nozzle. The mole grips do a good job of retaining the heat.
Wait for it to cool (this is important. Trust me I managed to pop the solder out on the first one I did)
Then once cool drill to size.

Simples. 

If you balls it up just re-solder. Pays to have a steady hand. First one I did the solder flowed over the threads. I just heated it up again and wiped the threads round to remove it.

Tomorrow I'm going to pick the fannymould up from Kev. This really is the last bit of the puzzle. I'll fit the Manifold nozzles up and then I'll crack on the Weekend. Once again I owe it all to the Guru's on here. I'd never of thought of doing that.  :y

Anybody who thinks this is a bodge. Get over it. I won't be buying anymore jets. I will now just take them out in 0.1 mm steps till I hit the sweet spot. If that turns out to be 2.5 mm I will open my tool chest draw, line it with broken glass covered in chopped chillies then repeatedly slam my genitals in the draw.  :-[ :-[

It won't be 2.5 mm. I was going to suggest starting at 2mm as mine's being a bit grumpy at the moment and they're 2.3mm

Let's hope your right. I'm not looking forward to the draw slamming.  :-[ :-[

Once it's running, have a look at the LPG injector durations when idling. From what I recall of Gaffers' conversion, if the LPG injector duration is dropping to 3ms then they start sporadically not opening as the minimum fuelling required is approaching the open/close time of the injector. If you're well clear of that, check fuelling at wide open throttle, and if that's OK, they are big enough.

I'll pick your brains when I pick up the manifold tonight. Been having a good read of the calibration stage.
