There are numerous LPG systems on the market that vary considerably in quality and price. Most modern vehicles have complex engine management systems and therefore require a sequential multipoint system that will work in harmony with the vehicle.

The Romano Sequential Injection System has been designed with the latest vehicles in mind. Prices range from £1050 - £1800 plus vat, approx.

Romano also have a range of LPG systems for older vehicles:

Closed loop mixer system - used on pre 2000 cars with electronic petrol injection and metal inlet manifolds. This was the most commonly used system until a few years ago and is still suitable for many cars. Price range is in the order of £850- £1250 plus VAT.

Open loop mixer system - used on old carburettor cars. A very inexpensive and effective system.
