8mm id if using rubber from memory and make sure its high pressure injection hose, however i would be tempted to opt for nylon hose for the main run with good quality rubber hoses either end, such as this http://www.ebay.co.u...=item20c47a5bf1 dont have the links to hand but you can buy all the fittings for that stuff online and its what all modern cars use

Maybe rubber is better if you have to bend it? Nylon hose seem/fell kind of hard, and maybe not suitable for bends?

Is there any difference how far from fuel tank the filter is? I was thinking to relocate it to more secure/clean place!
