My LPG tank is a 60 litre version,I would like to install a larger one at some point in the future to give a longer range/less trips to the filling station (my nearest is about 10 miles away) what are options please ?
Also I think my system might need a bit of tweaking. During the recent hot weather it took about half a mile from cold to switch to LPG. Yesterday when it was quite a bit cooler than it has been recently it took almost a mile and a half from cold start to switch over. :-/

torpedo or donut?

Torpedo.

Here's a good idea of what's available:

http://www.tinleytech.co.uk/sizes.html

360x892       80L fits nicely and still room to fit long items through folded-down rear seats.

The 400x930 100L tank would be about your limit, IMHO.

Note I haven't tried it, but based what I recall from when I was measuring up.

The tanks also only fill to 80% so expect about 64L fill from an 80L and 80L from a 100L tank.

I have the 400x892 (IIRCC) 90L tank and, TBH, I wouldn't recommend it. The 80L mounting points fall much more nicely

That said, as you haven't got the Bose amp and shelf it wouldn't be such a problem.

Be aware that the certificate for your system will become invalid as it has the tank serial number on it

Also I think my system might need a bit of tweaking

What you working this weekend? PM me a number and I may be able to have a look on the way back from London on Sunday. Failing that we'll arrange something for next weekend. Check you haven't got another airlock

i believe mine is an 80 or 85 litre tank. Fills to about 68 litre? It fits nicely between the suspension turrets. Can't say that I can fit long items past it though. In fact i've had to resolve the problem of accessing the boot release in case the switch doesn't work - I have short arms and there is no way i can reach the latch on the bootlid from the seats over the top of the tank - B&Q's finest bathroom light switch pull-chord tied to the latch and tucked in behind the seats Ugly solution but effective

Not wanting to hijack the post, but how would you check for that?

[albitz]

Was just getting excited at the thought of a 90L tank,didnt realise that the change would invalidate the certificate.Will have to have a bit of a think. :-/ :-/
Paul, your an absolute gentleman ...........Im working 7.30 pm to 730am tonight/Sat./Sun. Not working again until next Sat. and Sun- 7.30am tp 7.30pm.
So I will be around during the day this weekend, or if your coming back up the A12 early evening, I work 5 minutes from the A12, could go into work early and meet you there if it makes life easier for you, whatever suits you best basically.
Will PM you my number.

With the engine at operating temp. squeeze the heating supply pipes to the gas evaporator vigorously for a few seconds. If they get noticeably hotter & stay that way, you had an air lock which you have now removed

And the top hose

Thanks Phil... Yep, I was referring to coolant flow as Albs had an airlock before

If not an elite with self levelling I wonder if too big a tank will be too heavy for the rear suspension?

Seem to remember James fitting a 100 ltr in his cdx then asking about spring assisters as the back was too low. Then reading that the tank was nicked from his back garden, so he had taken it out.

 Could just have been tired springs I suppose?

LD has an elite iirc.

Another thought, if only a 60 litre cylinder, may as well have fitted a donut in the spare wheel well and kept the boot/through space, as mine is 60 ltr and still have all ny boot.  ....although donuts are more money to buy.

Update on the LPG runnimg problem.Every time I start it now it takes a long time to switch over.The coolant pipes (evaporator supply ?)are always cold, if I burp them they get hot and then the LPG kcks in. After talking to LD by PM (and also Daz on the phone)I went out and had a bit of a poke around. The pipe going into the HBV was hot, the bottom pipe from the other side of the HBV was also hot ,but the top pipe of the 2 (which is the one which has a tee to supply the LPG system) was cold. I swithched on the climate and put it on HI. The cold pipe immediately got hot (as did the cabin) and the LPG kicked in straight away.
My question is, does this mean there is a fault with the HBV or could it be something else ? No sign of leaks from HBV nor any loss of coolant btw. I can also feel vacuum at the HBV vacuum pipe. Does the HBV go wrong internally ? :-/

Your evaporator has been plumbed in incorrectly! Have a look at this from Lazydockers Howto on LPG Installation.

You need to take a coolant feed for the vaporiser. From experience, the best way to do this for the Omega is to intercept the coolant feed to the HBV and plumb the vaporiser in series (before the HBV) than to Tee into the heater pipes as suggested by most kit manufacturers. So, remove the "Helter Skelter" pipe and cut it so that you have a feed and return pointing towards where you have chosen to mount the vaporiser (O/S inner wing seems to work well)

 

Connect the coolant hoses to the connectors showing in the above picture and route them to where the vaporiser is going to be mounted.

But the system has been on the car for 2 years , this problem has only appeared in the last few weeks. :-/

Your evaporator has been plumbed in incorrectly!

Agreed. Some muppet has plumbed it in after the HBV so it only gets coolant flow when the climate is calling for heat.

All installs we have DIY'ed we have plumbed the vapouriser between the outlet on the coolant bridge and the HBV so it gets flow regardless of whether the heater matrix is in the circuit or bypassed.
