Hi everyone,
I'm new on here so please be gentle.
I'm doing an efi conversion on a bandit 12, but my question is relevant to any EFI conversion. My question is does it matter if the diameter of my fuel hoses / fittings are different throughout the system. So my fuel pump supplies the fuel rail via AN6 hose, then the rail itself is 4mm ID, then it widens up again to AN6 to supply the pressure regulator. I'm thinking the change in hose diameter will make the pressure regulator see a lower pressure than the fuel rail does and so allow the fuel rail too much pressure?
It would make more sense to me to run the regulator before the rail but I have read this is a bad idea.
Any thoughts welcome
Thanks for your time
Dan
