What diameter is the fuel line?

...and is it the same diamter throughout the system?

The hard feed/return fuel lines that run under the car from the tank are 8mm outside dia/6mm inside dia.

I changed all the flexible bits that come up from the bulkhead to the fuel rail the other day and used some 8mm inside dia fuel hose from work.

And its all the same sizes from the tank to the fuel rail

Yeah I replaced the soft pipe with braided 8mm hose.

So are the lines under the bonnet have an internal diam of 6mm then and you just swapped it for bigger?

 

[MarkTurbo]

No, didnt use bigger pipe. The rubber ones under the bonnet that go between the fuel rail and the pipes that run under the car are roughly 8mm inside dia
