LPG in its liquid phase comes out of the tank by means of the multivalve (which through the external filler socket is also used to refuel with LPG) and goes to the engine compartment through a pipe on which there is an LPG solenoid valve that allows the gas to pass through only with the engine running and switch on the gas position.
LPG level sensor is fitted to the multivalve it gives a signal to the LPG level led indicator installed inside the vehicle.
The standard cylindrical tanks are the most common and available in larger sizes (100 litres plus).
It may be worth mentioning that most smaller cars only hold around 50 litres of petrol and there are now a large number of LPG filling stations around the country so the days of having to drive a 40 mile round trip just to fill up are all but gone.
The doughnut (toroidal) and UFO style tanks hold around 40 — 75 litres. Think about it if you normally put around £20 or £25 of petrol in at a time you can get double the amount of LPG for the same price and not have to fill up as often, so unless you do a lot of long journeys you have to ask yourself: do I really need such a big tank? (A quick note: you can only fill an LPG tank up to about 80%; you will never fill it 100% ).
The easiest place to mount a cylindrical tank is against the back seat, and for tanks above 80 litres this is probably the only realistic option. In case of a rear end accident the crumple zone will still function as intended by the designers. The disadvantage is, obviously, smaller loading area in the boot.
The doughnut and UFO style tanks are intended to be fitted in the bay for the spare wheel. This type of tank is available in various styles, e.g. slim line, and in a multitude of sizes from 25 litres up to 85 litres to suite most cars, some are available that use the existing spare wheel mounts and thus simplifying installation.
One of the problems with using this style of tank was the lower capacity when compared to the cylinder tanks, however with the much improved availability of LPG from an ever increasing number of filling stations the need for large tanks has diminished. This style of tank is rapidly increasing in favour.
