John, what fasteners did you use up towards the nose? I need to redo my front fasteners as I'm not too happy with how difficult it is to get them situated when putting on/removing the hood.

I used the same fasteners that you used for the front of my hood. I did cut out a section from the bottom of the nose to make it fit around the bottom of my radiator. This allows the nose to set up higher. I also mounted bumpers to the sides of the car frame to have the hood rest on.

When I put the hood on I align the rear post from the Aerocatch first then set down on the front Quik Latches. 

Yes, the Quik Latches were a bit of a pain to align at first. I think that having he bumpers on the corners of the frame help with the alignment and mounting of the hood.

Just so I'm understanding you correctly, you cut a section under the nose (unseen from the top) to allow you to set the hood/nose on top without sliding it into place?

Yes I did. It is cut out the width of the radiator and almost the thickness of the radiator. I mounted a piece of angle aluminum across the bottom. and added some trunk weather strip to it and that rest against the radiator. The lower radiator mount is the one provided from Exomotive.

I think that my hood sets about 1 3/4" higher in the front than yours.

Thanks for the pictures and explanation. I'll be doing that this weekend!

Just a little update. Have not had much time to work on the project, I have been swamped with work. Looking forward to tourist season ending finally will be able to get the project done.

I have finished mounting the tail lights. Solved the fuel vent problem. Just some wiring to finish in the front.

Congrats on getting tagged!!! I like the lights. I have my inspection scheduled for June 23rd. The local DMV guys make it sound like more of a formality after all the documentation stuff being so strict.

John, where did you get your fuel fill? I'm Guessing it's from the marine world. I installed a Perko ratcheting fill and I'm just not happy with it. I like the look of the larger flange like you have. Any suggestions would be appreciated.

Bill,

The fuel fill is from Sparco, it is the same as an aircraft aluminum fuel fill. 
Here is the link to Sparco.

My second choice was one from Monster Marine.

I went with the Sparco because I found one used and cleaned it up.

One other place to check would be here.

What do you do with the factory tank's vent hose if you use a cap like the Sparco?

I used this vent from Atwood.

I keep my car in an open detached garage don't know if this would be safe for in home closed garage though.

So this lets air into the tank like the gas cap. What about venting positive pressure?

To a degree, does it need to?  Typically, and especially if my garage is hot inside, if I open the (pre-disassembled) Miata's gas cap, it releases pressure in the tank. I think the factory vent hose / pipe runs to the welded assembly that comes into one unit "before" the gas cap. So, if the factory gas cap has a one way valve to let air in but not out, that'd do the same thing as the combination of parts that Jon is using. I think.

My build is from a 2000 Miata only 1 fuel line no return line. No return positive pressure in the tank. I have the fill 1/4 vent hose and the tank charcoal vent linked to the overboard marine vent.

Oh you put a charcoal canister in yours? I was under the impression the vent was a mini canister.

I am not sure this solves all the issues that the OEM design was able to. Overpressure is the evap and charcoal canister and the gas cap was allowing air into the tank to replace the space the fuel occupied. Fuel exit and return doesn't really matter from a regulation standpoint, it just contributes to the issue.

I would think with the way it is setup there would be positive pressure in your tank on a hot day or if the car sits for a while. I am not sure how much it matters but I would think Mazda addressed it for a reason.
