LEAKING FUEL INJECTOR --- 1983 280ZX

I have a leaking fuel injector on a 1983 280ZX.

Do I replace the complete injector, or is there a seal which needs to be replaced?

Should I replace/refurbish all six injectors, or just the one which is leaking (since it looks like all six injectors come off at the same time)?

Could someone point me to instructions on the Internet somewhere, for removal and replacement of an injector? That is, the website address.

Any information enabling me to complete this repair myself is greatly appreciated. Thanks in advance.

Replace the injector. Do not drive the car till it is replaced. I'd go ahead and replace all six injectors because the car is 26 years old and eventually the others will go bad. New ones are not cheap.

Try google for replacement instructions using search terms like replace fuel injector for 83 280Zx. There are complete shop manuals online and self help sites, despite Nissan's quest to shut down such websites giving away free info. You can shop manuels at most bookstores online. I know ebay sellers have them for your car on CD-ROM and paper print.

It's the injector, the seals don't create a fuel leak and rarely is it the hose.

yes, they all need to have the same flow rate and mixing brand/age injectors creates all sorts of mixture distribution problems. Some info that may help, 84-86 300ZX non-turbo top feed injectors are the same as the non-turbo 280 injectors.

I've seen all three problems. I currently have a porous hose on my daily driver ZX, I've had leaking seals, and leaking injectors. I'm fabbing a new fuel rail out of aluminum stock to make the job easier in the future. Here's a link for all of the parts you might need. I've had good experiences with this company, but there is always ebay.
