Modifications

• Larger header tank.
• Catch tank. Fit a flat cap onto the header tank. Fit a pipe from the overflow tube on the header tank neck to the bottom of the catch tank. A Triumph sourced item fits nicely on the left-hand chassis rail. Fit the 7lb cap onto the catch tank and keep that tank half-full and the header tank topped up.
  
  

  With this arrangement the system will self bleed itself - especially if the rear of the car is jacked up whilst the system is filled.

Heater

The standard heater was a GT6 item held in position by a Ginetta moulding which is available from Ginetta Heritage. The heater doesn't work as well as it should because it takes air from a low-pressure area.
