It looks like that thing that causes you to die in a fire. The pulsation dampener. There is a page on the mazdatrix website. Checking...

Pulsation dampner. Very common failure and main cause of engine bay fires, must be fixed asap and do not drive the car or run the engine. You have 2 choices, buy a new one for around 125 or spend a few bucks an replace it with a banjo bolt.
Earls part # 997591, banjo bolt 12X1.25 mm. Should be able to order one fom Summit, Jegs, Aerospeed, etc. Replacing it with a banjo bolt will not harm performance. I replaced the PD in my 2nd gen simply as a preventative safety measure.

Just replaced mine with a banjo bolt... It is not necessary to remove the dynamic chamber to change that part but make sure the crush washer are well align when you tighten the bolt. I badly cruched one and gas pissed even more than before. Had to machine a new washer myself as it is a hard size to find. Since you are in Canada like me, i recommend NOT buying from summit. They have a internationnal handling fee PLUS the shipping. My 20$ banjo bolt + gas line attachement ended up costing 50$. Read the small print as I tought the handling fee was shipping.

Fuel Pulsation dampener. It's a little metal pod on the end of your fuel rail with a piece of sheet metal in it It should have a see through (faded yellow) rubber boot over it.. When the injector shuts closed, the pressure spike is negated by hitting the tiny sheet metal that springs back into place, it keeps your fuel rail from rupturing. There is a screw on it that tends to back itself out and it leaks right above the hot headers and is a huge culprit for nearly all Rx-7 engine fires.
Here is yours:

It was fading into obscurity again so I figured i'd help. Do you just use the washers that come with the bolt or do I need to find some new copper crush washers for the bolt?

Don't forget, he's got a second fuel pulsation damper on his fuel pump (as do all the rest of the GSL-SE's), as well. I wouldn't worry about any problems regarding the fuel lines, as I've never heard of that happening because of a banjo bolt update. You're already ahead of the curve in that you smelled the failing PD. Plenty of FCs burn to the ground by kids who don't notice or care when theirs fails.
