1For all types:
During a total overhaul the Metering Unit will be dismantled and all components cleaned. All parts are also checked for wear and replaced if necessary. Only in this way optimal performance can be guaranteed. Partial overhaul of a Metering Unit does not give optimal results and is therefore not recommended. 

Smooth operation of the vacuum-controlled injection system is largely dependent on the “Vacuum Diaphragm and linkage”. If there is any vacuum leakage this results in the mal-function of the Metering Unit’s supply of petrol to the injectors, causi2ng extreme fuel consumption.

After a complete overhaul, the Metering Unit will be tested and calibrated at our original Hartridge test benches before we send the Metering Unit back to the owner.

At the time 2 different Metering Units and 2 different inlet manifolds were produced for the Triumph TR-series. It is possible to convert a CR type ( TR-6PI 1973-1975 124 HP) to a CP-type (TR-5PI, TR-6PI 1968 up to 1972 160 HP). If necessary we can provide you with all instructions needed for such a conversion (adjustment engine and distributor). Just fitting a complete CP-injection system to the CR engine is not enough!.3

We are proud to have succeed in improving the reconditioning MK-I and MK-II system for the various Maserati’s and Triumph sport cars. Even though the components have remained unchanged, many technical improvements has been made!!
