Ok, so my major fuel leak is going to be fixed very shortly. I have

bought new O ring seals, the 6 new holders will be in on thursday,

and hopefully things will be replaced on sat.

My QUESTION:

Seeing as how the entire fuel injection system on this 79zx is all

stock and original, what are these injectors going to look like? are

they still going to be useable? can old injectors be cleaned and made

to be like new again? What about hoses? once all this is taken apart

is there anything else I should replace while I am in there? Things I

should be worried about?

I stopped by a mechanic and he said that its about an hour and a half

labour to do all this if everything runs smoothly... what could go

wrong? What are common lies of falacys that he may throw at me to

make himself more money, and make me go broke? He guessed about

$100(CAN) labour, is this realistic?

Thanks, and sorry for the long post

INJECTORS ARE PRETTY STURDY. YOU CAN REPLACE THE RUBBER FUEL LINES ON THEM IF IT MAKES YOU FEEL BETTER JUST BE SURE TO GO BACK WITH REAL FUEL LINE ( THEY CHARGE BY THE INCH). INJECTORS CAN BE TESTED IF YOU HAVE THE RIGHT EQUIPMENT. 99.9% OF SHOPS DON'T. IF YOU DON'T HAVE A MISS IN YOUR ENGINE NOW YOU SHOULDN'T WHEN IT COMES BACK

Things I should be worried about? I stopped by a mechanic and he said that its about an hour and a half
labour to do all this if everything runs smoothly... what could go wrong?

IF IT'S REPUTIBLE MECH. DON'T WORRY. IF THE CAR HAS NEVER BEEN APPART SOME OF THE FITTINGS MIGHT BE SEIZED FROM CORROSION.

What are common lies of falacys that he may throw at me to make himself more money, and make me go
broke?

HE COULD TELL YOU THAT THE INJECTORS ARE CRACKED OR CLOGGED. AGAIN REFER TO FIRST ANSWER.
He guessed about $100(CAN) labour, is this realistic?

SAVE THE $100 AND BY A HAYNES MANUAL AND SOME DESENT CRAFTSMAN TOOL IT IS AN EASY REPAIR YOU CAN DO YOURSELF IN ABOUT THE SAME TIME. FIXING THEM IS HALF THE FUN OF OWNING A ZCAR.

Changed all of mine on a 77 280Z several months ago for the same reason. Fuel leaks from bad hoses mainly were making me crazy.
I knew I had one dead injector and suspected I had others that might not have been working properly plus I knew I had a leaking hose or two at the lines.
I replaced all of mine with rebuilts and have been completely satisfied. It took me more than an hour but it was fun and I learned a little more about my engine. Was a good exercise. Suggest you try it yourself. Good Luck

I would also recommend you consider replacing the injector connectors. If they're the original ones they may break when you disconnect them. 20 year old plastic can get a bit brittle and new contacts would be nice. Not very expensive either.

I just got finished troubleshooting a pesky injector prob on my 81zx. I had a friend walk me through takin off the 'rack' the first time. Hint: you can replace the metal injector line with injector hose if the old line is tweeked or hard to deal with. Really if you have a socket set and philips you can do this whole job yourself bro ! Luck 2 ya

Where did you buy the rebuilds and how much where they?
