I just recently bought a 280z and everything was great until I started to smell fuel while driving it. So I popped the hood and there is a leak on this rubber hose coming from the fuel rail to the injector. I just don't know the name of the part or if I have to buy a whole new injector or what..

 

It's just fuel injector hose. Fairly common for 30+ year old fuel hose to get brittle and crack / leak. Just yank the rail and replace all the hose (you can buy fuel injector hose for like $2 - $3/ft at your local parts store.

It's kinda time consuming to get the rail off, but not complicated. Make sure you download the FSM from XenonS30

 

ok thanks man, thats what I thought it was. Just makin sure. I really appreciate it.

 

Once you get the injectors off, the pintle caps will be very brittle so be careful. Replace all the injector hoses with the right type of hose. Split the old hose with a razor down to the metal collar. Take a soldering iron and burn through the hose left behind the collar you cant cut through, and yank the hose off. Reuse the collars when installing the new hose.
