I don't know if this will help because I have the Eclipse Spyder GS. But mine is mounted to the passenger side firewall behind and to the right of the battery. I needed a 19mm wrench to secure the filter, and another 19mm socket wrench for the top screw. You will have to place the securing wrench in a way so it's braced up against the firewall, or battery mount so that it doesn't move and you can use both hands for the socket wrench. Yours may not be as tight as mine was, but it took all my body weight (185lbs) on a long handled socket wrench to get it to budge. I thought I broke it, but I didn't. For the bottom screw, you will need the same 19mm wrench and a 14mm wrench, bracing the 19mm wrench the same way, you will have to loosen the 14mm nut, only this time, you won't be able to see what you're doing. I had to do it all by touch. Make sure to use both new copper washers for the top bolt. I reinstalled the battery and mount before I checked to see if it would leak when started. I found out the hard way and had to take everything back out to replace one of the two washers for the top bolt. If you can, start it before you reinstall the battery and mount. Hope this helps.
