To those of u wondering about difficulty...DO IT. Period. As far as the benefits I havent finished the car yet, but as far as experience needed/do i want to mess with this....DEFINTELY
Print Brain's instructions/post, get exactly whats on the list(21/64bit is common to find, might already have one....the tap/fittings/etc Advanced sells them, and ge the bit there like i did), and do exactly what he writes, it IS that simple and newby-proof.
As for "do i wanna mess with the fuel system" jitters....Its nothing. Esp if u alread took ur injectors off, u did 70percent of the work. The lines just pull off, perfect example about the shotglass of fuel(shop towel under u is all u need, if that) and open the gascap first. I wrapped a shop towel around a pair of lock pliers, and pinched the line to be extra safe. Make sure u dont lose the plastic spacers under the 3 bolts, wont go on the same without them(but they can be bought), and be gentle and patient with the clips on the injectors(which u already did).
Finally JB weld is like peanut butter and jelly, but thicker. U take a piece of cardboard, or a plastic knife and u spread it kinda. It hardens and seals, dunno how, magic maybe but it does...
And thats it, cheap insurance is the way I saw it, and I did the SAME thing and sent my injectors out, then wondered...hmmm should I?

Okay, so i have my fuel rail off, which was a bit harder than i expected, but then again, i'd never done it before. Anyway, i see how in brain's post it says to be careful not to lose the spacer. Well, i think i have lost the spacer. I have been looking for it for a while now and no luck. Is that something i can pick up at autozone or something? I know, i know, im a dumbass.
Thanks in advance.
Thanks in advance.

The spacer is a black plastic washer that sits in the intake manifold to space the fuel rail to the right height. They're about 1/8" thick or somewhere around there. Be careful, is spent 30 minutes looking for one i dropped. It was lodged between my oil pan and subframe, could hardly see it.

Im sure u could find the spacer at either Autozone, if not Mazda...
I would take a real good look tho, like posted above they tend to get invisble when on the subframe..
Did u hear it hit the floor? Or just rattle down? Check for it...worse case u could prob run w/ just 2, 1 on each end and dont tighten the middle bolt too much...
Have u started the actual mod yet? after rail is off it should only take like 15min with the right tools, plus jbweld curing time...
