What size should I have on my fuel lines?
A rough guideline is usually 1mm inner diameter per 100hp on Petrol. Or 1.3mm inner diameter per 100 hp on Ethanol.
Example:
800 hp gasoline = 8 mm inner diameter.
800 hp ethanol = 10.4 mm inner diameter.
Which fuel hoses should I have?
If you are going to build a new fuel system, you should use PTFE hose. Nothing else. This is a plastic hose that can handle both petrol and ethanol. This hose is used by OEM manufacturers precisely for reliability.
What torque (tightening torque) should AN fittings and hose have?
