I recently put autoLite 764 Dbl plat. in and I have to say I hate them..... So I went and got some NGK TR55. The questions is last itme I went for some parts and I came back and my buddy had the fuel rail off and said he had to take it off. My question is do I havef to take the fuel rail off to change all the plugs and their boots. I also started out to do this, this moring and it is cold as he// out side....

Yep, platinum plugs are garbage ... they're only good for the people that leave their plugs in for 50-100k miles. Always go with copper. There's no need to pull the fuel rail so leave it alone. You can easily get at the tougher ones by using an extension with a "wobble" head or use a swivel for more room to get at them. Don't forget a dab of anti-seize on the threads and a little dielectric grease inside all the rubber boots (or on the tops of the plugs).

No - you do not have to take the fuel rail off at all. The plugs on the driver's side near the battery are relatively easy to get to. It's the two plugs near the windshield on the passenger side that are a pain to get to. The only thing you need is a very good swivel for your ratchet, a long extender, and a short extender. Some plugs you need to get way down in there and others you have very little room. Also, don't forget to use the anti-seize on the boots and the grease on the threads. Good luck!

I thought the autolite 764s were copper?? Do they also come in Dbl Plat? I wasnt aware of that. Anyways... you do NOT have to take off the fuel rail, it will flex up a lil bit when pushed on it and should give you enough clearance.

The only tools I needed for the job was a 6in extension and a 1 ft extension connected together to get at those last back two on the passenger side. Other than taking my time on those two, I can have the plugs changed in ten minutes. Like mentioned already - make sure you use the dielectric grease on the boots and grease on the threads
