Classic cars forum & vehicle restoration.

Tomorrow I will bring my '67 Jag 420 to the local LPG fitter. The car already has the rest of the system fitted, the only thing needed is spraying nozzles fitted in the air cleaner trumpets just before the carbs.
If the space, the air cleaner trumpet is very close to the wiper motor, had been bigger I would have installed it all myself using a generic SU or Stromberg carb mixing ring.
I have been using and driving LPG equipped classics for about 15 years now and it is excellent. I did 50K miles in my Triumph 2500 Mk2 in four years on LPG. Smoother running, cleaner engine oil. Some drawbacks or things that need to be remembered are points that were mentioned before like tip top condition of the ign system, likewise cooling system, likewise the valve adjustments need to be always good, there is loss of space in the back, the exra weight of the tank maybe needing heavier springs at the rear (I have used extra springs around the shockabsorbers on my Mk1 Triumph 2000 with good results).
Also, in the case of Triumph, much more frequent valve adjustments are needed and the valve seats will disappear very soon if no hardened seats are used. If harder seats are fitted, it is no problem.

So all in all some things to be dealt with but it is aways a pleasure to fill it up for a third of the petrol price! (I am in the Netherlands).

I had an interesting 'funny' with my LPG car the other day. I filled it up, only for the thing to sit there, hissing freezing vapour out of the filler neck. I thought perhaps I'd overfilled it or something so carried on my way. It was still burbling away to itself when I arrived home, leaving a frosted vapour around the bodywork surrounding the filler.

Turns out the spring-loaded shut-off must have had some grit in it, and wasn't self-sealing properly. That might explain the prevalent whiff of gas enveloping the driveway. A few prompt shoves with a thin screwdriver freed it it off (after I got covered in a vapour cloud of LPG) and now it seems to seal ok. I've filled up since then and had no more problems. I'll have to make sure I keep a long screwdriver and a pair of gloves in the car, in case it happens again.
