nothing special ... you will have to move the fuel line out the way ... move it as little as possible and be careful not to make a kink in it. There is a copper "crush" washer on the bottom of the injector, make sure the old one comes out of the bore and it is clean in the bottom before installing the new injector with a new washer on the bottom. You can use anti sieze to hold it in place. you will probably have to replace all of the return line fittings, hoses and o rings as once they are disturbed, they will leak and cause hard starting problems. Good luck.

I use antisieze to lightly coat the complete barrel and threads of the injector. This will allow removal of injectors should carbon accumulate in the injector bore as result of a failed copper seal.
If you run into a carboned injector bore, bring that cylinder to TDC. This will stop large chunks from falling into the cylinder and causing a hydrolock/carbonlock. Removing the GP can allow vacuuming of the injector bore.......not recommended to blow the dirt out as it may blow it into the cylinder although there is only a 35 thou gap.

I replaced my injection pump, injectors and return lines this past weekend. I have several shop manuals, but the instructions from this website are FAR better:

Excellent step-by-step instructions, great illustrations and pics; this is a very easy to follow set of instructions. I printed it out - it came to 10 pages - and used it instead of my manuals. Piece of cake! You'll only be interested in the part about injectors, but it's well worth the time to print it and read it.
