Our FES Autogas trained installers around the UK will fit the best FES Autogas
assembled LPG kits with corresponding technologies for different types of
engine and vehicles, needless to say an old carburetor mini would have a
different system to that fitted on a new BMW, but both would run just as
well as each other.
The installer would next look at the best size of tank for you and location
of filler point. Because FES Autogas installers work with classic and
expensive vehicles on a daily basis they understand that the filler needed
to be sited in a sensible position. They will try not to locate them too
low down under bumpers as this is very unpractical when going to fill up
and when you’re wearing your best clothes! We've found on some vehicles the
filler can be mounted in the same place as you fillip with Petrol under the
flap. They can advise on size of tanks to fit most applications but again they
involve you the owner in this part.
If you’re using the vehicle for specific things then there is no point the
installer suggesting a small tank if you do long journeys or a big tank if
you only pop around town or carry loads? We can supply our customers with a
huge range of tanks all pre assembled in house here at FES Autogas and with
test certificates for next day delivery to our customers.
When fitting the LPG system our installers find that we can, whenever
possible, run the pipes and cables where existing routes are. The only
place you'll see some noticeable changes are in the engine bay where the
gas line will go into its second safety shut off solenoid (first one in
tank) before reaching the vaporizer, which on some occasions comes with a
third, shut off solenoid. These gas solenoids are fitted so that the gas
will be stopped if the engine stalls and has the ignition turned off - making
leaking gas a non occurrence.
When the engine is running and at the vaporisers the liquid becomes a gas
before travelling to the induction mixers as on earlier carburetor engines or
injectors for later engines. For later generation vehicles, with advanced
injector systems we can supply feedback systems and the latest OMVL Dream
21 Gas injection system all pre assembled to be vehicle specific and tested
before it leaves us. These Dream 21N
systems use the cars existing computerised ECU (engine control unit) which
interfaces with your car's existing sensors.
For instance, the TPS (throttle position sender) and the lambda sensor
(which normally adjust the petrol mixture) are all feedback via the cars
petrol ECU to the gas ECU so that the engine will run at optimum
performance and efficiency.
We don't supply DIY kits as FES Autogas as
we are a trade only suppler and all our kits are assembled in house for
vehicle specific orders and to our trained dealers but we can offer
discounted training courses to DIY installers to help them step on to
becoming a fully authorized FES & OMVL installer should that be of interest.
Inside the vehicles interior is where you find the other noticeable change,
the gas/petrol changeover switch. This as it says is used to choose which
fuel you want to run on. They need to be sited so that the driver can clear
see them to switch between fuels but also to see the LEDs which give tank
amounts so you know when you’re running low.
On carburetor cars you have a manual change over switch but on injection
cars you have a switch which allows the car to start on petrol but after
passing pre set revs changes the fuel to gas.
The tank gauge has 5 LEDs, 4 green and one red. Each of the 4 green lights
representing roughtly 25% capacity with the fifth
red light warning that gas is about to run out so tank needs refilling or
you will have to switch back to petrol.
Once fitted the LPG system will make no major difference to any servicing
requirements to your vehicle. Infact we can easily say that the service
intervals could be stretched. With running mainly on gas the spark plugs
and oil would last much longer in optimum condition, although we do not
recommend increasing service intervals as many other important components
such as brakes and air filter would need servicing at normal factory set
The fact is, when your installer orders a
pre assembled FES autogas system, they and you will be assured you get the
right parts and the right system for your car. There is no such thing as a universal
