Getting kids around cars and giving them something to be passionate about is such a gift. Those small moments can have a profound impact. I went for my first ride in a Caterham when I was seven years old, and looking back, that experience probably played a big role in motivating me to pursue an engineering degree. My capstone project was a stress and strain analysis of a Locost chassis. Now, decades later, I’ve been fortunate enough to buy the very same car I first rode in as a seven-year-old. Today, my own kids (seven-year-old twins) absolutely love riding in it.

Thanks for the offer, Dan. I may be in touch.

I will very happily take these! PM sent!

Updated post to include roll cage.

From my non-automotive/industrial experience, if these sensors have an LED they typically pulse ON/OFF when triggered. If you're sure a metal object is passing through the viewing area, and you're getting nothing out, it's toast.

I'm not certain, but I think engine OFF, ignition ON is legal in most states.

I leave my ignition ON and watch the gauge as I fill. When I hit full, I stop. I probably don't quite get it as full as I can, but no mishaps yet.

Thanks @JohnCh It’s nice to hear about PET. I work in the industry and actually tried developing a recycled PET filament about a decade ago. It didn’t gain much traction at the time, so it’s great to hear it’s being used now. It’s a good material and readily available. I’ve also been experimenting with high-durometer TPU in the engine bay. I’ll report back on how that goes.

There is some good real estate under the steering column that I decided to put to good use. I used some brass heat-set inserts for threads. For everything outside the engine bay, I use PETG with carbon fiber. I highly recommend it. This area is a perfect fit for an Element Extinguisher. I realize these aren't as good as a bottle of novec 1230, but it will probably be sufficient for my needs.

@hahuang65 I am not sure how easy it would be from underneath, but if you can get the length, width, and height, you can calculate the approximate volume. Gallons = (LxWxH)/231

Curious why you'd remove the regulator. If the mechanical pump is maintaining 2-3 psi, maybe there is no benefit?

Can you get some rough measurements and calculate the capacity (roughly)? Then you know if you can only put 5 gallons in a 10 gallon tank, you have a problem. I am not exactly sure what that problem would be, but it's a starting point.

Great article and photography!

@IamScotticus fingers crossed. I'd rather be than wrenching at the moment.

That sounds quite manageable, and much easier than taking the head off. Looks like I'll be going after this as soon as the seals come in from Burton. Hopefully, they are the right ones
