4mm and 6mm on the vacuum lines, you can get silicone hose cheap from ebay or rubber hose cheap at any auto parts store. As for the fuel line you need to make sure and get High pressure fuel injection hose not just any fuel line. I recommend going with oem on the hoses, though it's very expensive. I believe oem is 8mm if i remember correctly, alot of people dont want to pay for the oem hose and you can substitute it with 5/16 fuel injection hose which is just slightly larger than oem. Napa carries some gates hose for a decent price or goodyear j30R9 is another popular hose substitute.

3-4ft of vacuum hose for both sizes you will have extra likely but it's cheap. Fuel hose if you want to be safe 6ft. If you want to save money go measure out your fuel lines and then order a little extra just to be safe.

Could always see how far the 3ft will get you and order more if needed. It's been awhile since I replaced the hoses with stuff in stock location's so i cant remember exactly how much I used.

Just did my under-hood fuel lines a few weeks back...your 3 feet may not quite handle the engine compartment as there are four 8-15" pieces, plus there are several small but important pieces to do as well (f.pressure regulator, f.dampner) down underneath things in the intake area. This does not include the injector fuel rail hoses and a few other well-buried pieces such as the fuel line from the tank/fuel pump, so 6 feet is a good number for ALL fuel hoses I'd think.
Also, be SURE to get the correct fuel injection hose clamps as well- NOT the "normal" slotted band/screw type as they will eat up your hoses when tightened correctly and potentially cause leaks and loosening.

those are the lines i plan on doing during my plenum pull, i can do the other ones at anytime because there "right there" is 3 feet enough for those lines connected and close to my fuel rail??

Yes 3ft will take care of all the stuff on the top of the plenum and the fuel rail hoses.

Yep, 3 feet will do those small pieces...and more needed obviously to do the others, which would be recommended. :dblthumb:

The ZSpeed kit is nice because it uses the constant tension clamps.

IMHO, ONLY use Nissan OEM fuel hose. Anything else is begging for trouble.

I got 20 feet of each 4mm and 6mm hose when I did EVERY line with my engine out, and still have a bunch left over. I skipped the kit because I wanted two different colors.

Silicone is better than rubber for longevity. I got mine from www.Hosetechniques.com
