General Information Triumph TR MK-II System:
Sport-Cars from the "sixties" such as the Maserati Mistral, Sebring and 3500 GT Iniezione as well as the Triumph TR-5 PI and TR-6 PI were equipped with this vacuum fuel injection system. The MK-II system used on the Triumph TR-5 (1967) is almost identical to the MK-I Metering Unit (Maserati) and has no problems what so ever.

Metering Unit all types:
The reconditioning of a Metering Unit MK-II consists of a complete dismantling. All parts are cleaned and checked for wear or damage and, if necessary, replaced with new parts. Only by following this procedure we can guarantee optimal operation. Partly reconditioning of a Metering Unit can lead to inferior results!
