How gas works By GasResearch Australia
VVVVVVVVVVVVVVVVVVVVVVVVVVVVVV

A typical LPG system consists of the following parts. Firstly, there's tank (usually boot mounted)
that contains LPG under very high pressure. In fact, the pressure is so high that the fuel is in liquid form.
It flows forward through a filter/lock-off valve, a valve that only opens when there is an engine
rpm signal sensed. This is for safety, so that LPG cannot flow from the tank when the engine is stopped.
The LPG changes from a liquid to a gas in the converter, which is heated by connections to the
engine cooling system. Converters are classified as 'simple' or 'complex'. A simple converter
has no provision for external adjustment - all it does is change the state of the LPG. A complex converter
has adjustment screws - for changing idle mixtures, for example. Following the converter the
LPG is in gaseous form, so it can be added to the intake system of the engine. Of course,
the addition of LPG must be in the right proportions to the mass of air being breathed,
otherwise the air/fuel ratio will not be correct for the operating conditions of the engine. The device
adding the LPG to the intake air is called a mixer. Mixers vary in complexity, depending on which
converter they are working with. The simplest mixer is called an Amos Ring, and it comprises just
a venturi (flow restrictor) and a gas pipe connection. The pressure drop caused by the venturi
encourages the gas to flow through the tube. This simple mixer needs to be used in conjunction
with a complex converter, so that the correct adjustment of the air/fuel ratio can occur.

Impco variable Mixer ring ... gets rid of the restricted top end (availability is getting less and less though).

Denso Iridium spark plugs from Toyota (for the Ford ... looks it up on the Denso website) ... as the same as the Ford XR6 Turbo plugs (and EGAS plugs) ... but at around $6 a spark plug ... are a cheap alternative compared to FORD or NGK plugs.
