I'm very new to the Datsun world.  And I need to buy fuel lines from the tank for my 1980 ZX.  I've been to Zcar source and Z car depot and some others so far with no luck.  What is the best web site for me to go to?  I would like to get the rubber filler neck most badly.  

 

I might have seen one here. I know nothing about the seller.

I don’t think I’ve seen any new or reproduced ones.

Also, sorry it’s a lot of unorganized parts

Maybe someone can tell if a 240z fillerneck could be made to fit: partnr: 17208-N3050  they are around 159 dollars.. at courtesyparts.com.

(you have to close off some fueldamp tubes that are on the orig one.)

The steel part may be available here: https://zcarsource.com/fuel-systems/gas-tanks-components/gas-filler-hose/

I saw a couple that included the rubber coupler on ebay. 

 

I did some more searching. The hose piece is NLA, as I suspected.

You may be able to take measurements of your old hose, if that's what you need, and find parts on this site to fabricate your own: https://www.fillernecksupply.com/1979-1980-1981-1982-1983-nissan-280zx-fuel-filler-neck-gas-tank-pipe/

 

As Steve alluded to, this is a good site to look at parts diagrams

Sometimes you can find parts by googling the part numbers. Many times they are available in Japan but shipping can be a killer.
