Don't buy it. The overfill tank does get slightly pressurized due to fact of volume displacement in a sealed tank but a lot are vented. Tire pressure gauges must be pretty smart to compensate for atmosheric pressure. With your reasoning tires/tanks etc would loose pressure as the evlevation went up. A tire/tank/container inflated to 35 psi at sea level (14.7) will still be 35 psi at 10,000 (10.2) measured by the same gauge. If atmospheric does have a acting force in pushing coolant out of a tank why doesn't any fluid in any open container come out? Like my beer in a bottle here?

Goffer,the Aerospace looks like it has a barbed nipple so it's hard to say if there is a tube on the inside but if it doe it will work.
