Diaphragm, fuel sealing, Metering Unit distribution section to metering section. With the introduction of E10 petrol containing 10% ethanol it is vital that fuel system components are compatible with this modern fuel. Our diaphragms are made by a manufacturer who supply the JCB machinery company. They are in constant contact with fuel supplies to ensure the materials they use are compatible.

We are assured that the diaphragms we supply are compatible with E10 fuel.

Please be aware that ANY additive used in a mechanical fuel injection system where fuel is constantly passing around the system at high flow rates is likely to cause problems unless the particular additive has been specifically tested on Lucas mechanical Petrol Injection. We know of none. It is also worth noting that here at RevingtonTR we use NO additives as they are unnecessary.
