Hi I'm looking for some advice on which material to use for a fuel line, from what I've read kunifer or PTFE are the best but I also wanted to ask what gauge to get?

I have a twin port 1600 with single carb but have a set of twin carbs to put on.

I plan to run the fuel line down the outside of the tunnel similar to the brake line.

Appreciate any guidance anyone may have.


Cheers,

Neil

Tank outlet is 5.6 mm so you need to step up to 8mm and you may need to step down to the carb or carbs. Larger webers etc use 8mm.
Fuel injection hose has thicker wall and hopefully lasts longer than standard hose.

WHS ^^ 
And an easy and inexpensive way of stepping up and down are those cheapie "annually disposable" plastic inline fuel filters as they are often stepped to accommodate both sizes.

Standard 5.6mm pipe, converting to 6mm O/D ptfe (ethanol resistant) lined aeroquip for me. Pressure regulated down to feed twin Kaldrons.
Works for me ;-)up
