fuel pipe size?

[Jez]

After various patch repairs over the years, the time has come to fully replace the ridged fuel pipe that runs from the tank to the engine bay. Looking at classic cars suppliers, the three common sizes seem to be 3/8, 5/16, 1/4 inch. Does anyone know what is the correct size for the Maestro? (mine is a EFI)

Just been an checked mine and both supply and spill return are 9mm or 3/8 in old money. Wouldn't think there would be any difference between Turbo and EFi in this respect.

I would measure the pipes under the bonnet if I was you, I'm not sure that they are all the same, 5/16" is a possibility, easiest way to measure is with an open ended spanner over the steel pipe.
