Fuel tank to fuel pump pipe bore
« on: September 21, 2014, 16:19:53 »
Hi all,
Can anyone give me the inside bore of the fuel tank to fuel pump pipe.
I have just changed the pump out pipe, but the tank to pump looks a larger bore and I want to get the right pipe, before taking this off.
Thanks Rob

The line going from the tank to the electric fuel pump is about 12 -13mm (1/2").  Low pressure fuel hose can be used here. Do not use coolant hose.

There are two different tank outlet sizes, 10 and 13 mm. See my thread on modified fuel pump.
