I have a 1975 280Z and want to replace the large vacuum hosed. There are 3 of them. they appear to be different sizes from about 1/2" ID to about 5/8". Anyone have part numbers for ordering them or just find something close at the local parts store that is fuel rated? Thanks

 

Yes just take them to your local parts store and ask for replacements. There's no need to buy one from Nissan when they are $0.10/ft at your parts store.
