A range of fitting assemblies suitable for fitting to Series C Fuel Tanks to allow the return of diesel fuel back to the tank from the engine.
Choose a hosetail assembly for flexible rubber hose or a compression assembly for copper return pipes.
Both metric and imperial sizes are available for copper pipe.
These assemblies simply screw into a 1/4″ BSP female thread on the hatch plate after drilling out the blanking part below the 1/4″ BSP thread.
Tek Tanks would normally fit the return assembly for you if ordered together with the tank.
Remember that flexible pipe is measured from the inside diameter (bore) and copper pipe is measured from the outside (OD).
Be careful when measuring copper pipe. The difference between metric and imperial is very small and does make a difference.
Metric 6mm is not the same as 1/4″. 1/4″ converted to metric is 6.35mm and will NOT fit a 6mm compression fitting.
A micrometer or vernier calipers are usually required to measure copper pipe accurately.
