Anyone know what these do?
Does it regulate the propane temperature with coolant?

So Hank Hill would approve of this use of propane?

I am sure sales are up in racing season so he would probably approve.

Since propane is stored in the tank as a liquid it needs a regulator or vaporizer to turn into a gas then sent to the mixer.

Those are to warm the propane and turn it into a gas. Probably a regulator in those too.

Also the warmer the propane the more efficient it is. The hot air balloon folks put heating blankets around the bottles.

What they said^^^

Also acts as a failsafe to overheating. If they're mounted at or near the highest point, your fuel freezes and the car stalls before the engine overheats in the event of coolant loss. Not that this was engineered into them, just a byproduct.

Ask me how I know.

Smoke and mirrors.

Look like ballasts to me 😉
