how much do they normaly take?

Hi

Just got a 1988 devon moonraker 1.9 few weeks ago. and it has a LPG convertion

Now the the dealer who i brought it from didnt realy seem to know much about it. like when i asked where the LPG tank was we had to go looking, found it where the spare wheel should be.

when i was driving it he said that the LPG tank was empty. However when i filled up it only took 27 liters.

there is a little green light under a picture of a petrol pump on the fuel switch over (which has the logo of 'bristol' on it). and i assumed that this would go red etc when the LPG was low. however the engine stated to struggle etc, so i assumed that the LPG had ran out even though the light was still green.

the tank took 37 liters this time?

this seems a very small tank if its correct.

any ideas?

LPG tanks only fill to 80% capacity to allow for expansion

somewhere on the tank there should be a plate with the capacity on it

Sounds normal to me.

My last green LED is still lit when it runs out.

Different fill stations seem to get more or less in the tank.

3 weeks ago I only got 39Ltr in from an empty tank.

Keep the ingnition components in tip top shape and DONT use fancy 3 tip, or platinum spark plugs.

It's good though innit

yes - I've been told this too...

Just out of interest...why can't we use the fancy spark plugs?
And what bit of the ignition should I be watching??
(sure that all is well at the minute as she is running fine)

thanks
Emma

Steve where are you

As far as I know it is because the gas needs a more powerful spark to ignite it.

So a good coil, good HT leads ( often overlooked, and don't buy cheap Halfrauds etc types ) a good dissy cap ( use genuine VAG ones ) etc help starting and smooth running.

As for plugs, it's summat to do with the intensity of the spark ( Steve ? ) and I do know you are supposed to gap them less than the norm to xxx thou ( Steve ? )

E D I T = see Wiki at http://www.club80-90.co.uk/wiki/index.p ... park_plugs

Steve how is your injured foot mate ?
You should have your feet up and forum'ing away like mad

I'm off to start a thread ( or look for an old one ) re adjusting the gas feed valve ( aka "Power Valve" )

had multi point (spitfire) plugs in for the last 2000 miles (were in when Steve fitted the lpg system)and no probs but will change them when the service is due
seems to run fine, acceleration etc

Not too sure but I think its more likely to backfire on the bosch platinum/3 spark ones.

if anyone is interested have now changed my sparkplugs and seems to run slightly smoother with the new plugs (old plugs seemed to be still in good working order)
will see if mpg improves and post accordingly
