When I first installed my water injection and for the last 2 or 3 years, I've used a tank that was rather large, probably 1.5 gallon or so. Recently I decided to clean up my hatch area and instead use the stock rear washer bottle as the tank. Well, that bottle is roughly 1/3 gallon, so needless to say I really have to watch the fluid level a lot more now. Now instead of refilling it every couple months I'm refilling every day or so. However, I am driving the car A LOT more often now and for longer distances.
I have the FJO generation 2 kit and I think I have the map set fairly conservatively, much more than it was anyway, but I'm thinking of thinning out the map a little more. A couple times now I've gotten to the end of my trip and noticed the bottle is empty. These trips are usually from Loveland, CO back home to Colorado Springs (roughly a 2 hr drive). Going to Loveland I don't run out, but coming back home I run out, I'm assuming because Colorado Springs is higher elevation.
Anyway, I've thought about modifying the stock bottle to make it larger, but I also want to use a fluid level sensor. I'd like to keep from drilling any more holes in the bottle if possible, and after doing some searching I found these...

I emailed a company in the Denver area about the ExOsense in the first link, and they said they need to know what material the bottle is made from and also the thickness, then they can give me a quote. Does anyone know the material Mazda used to make these bottles? I'll measure when I get home, but I have no idea what material it is. Would that be in the FSM? If so I can look it up. Also, I'm wondering how to power it. I'm not so good with electrical outside of being told where to connect and splice wires, so with this running off a different voltage than the car, I'm not sure how to power it without destroying something lol.
They also said the sensors are bought in pairs, so I'm thinking about running one closer to the bottom and one about the middle.
If this works out, it might be a good alternative to putting even more holes in the bottle and giving it another possible leak point. They sent me a PDF but it's too big to attach, even when zipped.
