Vapor canister hoses

[Pomorza]

Hello all

So the lines that go to the tank into the vapor canister (or whatever that is called) in the back of my 280z are all broken in half (literally from age and heat) and leaking all over the place. I took it to my mechanic as, well I don't feel like being covered in fuel in 90 degree weather but they're having a hell of a time trying to get hoses. So does anyone know where to source these hoses or what hoses can be used or what to do? I saw the thread about doing this in a 240 but I'm not sure if that applies to 280s.

Thanks

Have you or the mechanic tried Nissan? All the hoses for a 240Z are still available, it might be logical that they are also available for the 280Z - perhaps even the same hoses. Check the online parts manual to get your part #'s then check Courtesy Parts online. They are not especially cheap but will absolutely fit - especially important for the ones with significant bends. Don't overlook the seals/grommets where the hoses enter the interior from the tank, available from Mike at Banzai.

Are you attempting to maintain a stock appearance? If so follow Jim's advice. Otherwise you should go to NAPA with your old lines and get std. fuel line replacements. For example, For my '78 280z, I went to NAPA (on advice from others on this forum) and purchased 5 feet of 5/8" fuel line, 8 feet of 1/4" fuel line, 1 foot of 3/8" fuel line, 1 Clear(See Through) 3/8" Fuel Filter. Make sure that is NOT fuel injection (EFI) rated. Fuel injection line will be about ten times the cost and it is not required because you are replacing lines that are on the tank and before the fuel pump. Finally, only buy 1 Foot of 1/4 EFI Rated fuel line.

So what to do with all of this hose?

The 5/8" line should be cut in two lengths: 1 foot and 4 feet respectively. 1 foot will go from the Fuel Filler to the Vapor Tank, the remaining 4 feet will go from the Fuel Tank to the Vapor Tank. There should be plenty of line to practically route from tank to tank since this is not a 'Formed' hose.

Four Feet of the 1/4" hose will go from the EVAP line on the underside of the car near the fuel pump to the top of the Vapor Tank. Another 4 feet of 1/4" line will go from the top of the Fuel Tank to the side of the Vapor Tank.

Use the One Foot of 1/4" EFI Fuel hose on the return line from the EFI system to the Fuel Tank.

Cut the 3/8" Fuel Line in half and install the Clear(See Through) 3/8" Fuel Filter. Install this line between the tank and the Fuel Pump. The Clear Fuel Filter will allow you to see what the condition of your fuel before it gets into the EFI system.

Make sure to discard the tired, old style hose clamps and replace with modern ones. We are talking about fuel systems here -and you want to avoid dangerous leaks and harmful vapors.

The cost for everything I just described above was under $100 bucks.

If you can't find the 5/8" fuel line from an auto parts store, try a tractor supply company. If not there, then I know you can get it from Hampton Rubber (http://hamptonrubber.com/). They're not a mail-order company, but if you ask them nicely, they'll ship you almost any rubber item you could possibly imagine or need, including all crazy sizes of fuel hose.

Hint: Use Goodyear E-Z-Coil doodads to make the tight turns in the 5/8" line.
