CNG discharged when temp is 102 degrees

[Ronwald027]

Reading some sort of emergency booklet, I noted that when the temp inside the tank of my GX reaches 102 degrees a valve opens and my cng is exhausted to the great outdoors. I know during summer weather, particularly in Palm Springs etc, temps inside a closed car get way, way high. Why don't I see a ton of complaints regrading empty cng tanks?

That's 102 Centigrade, Well over 200 F. The intent is to vent the gas if the car or garage is on fire , to prevent a tank rupture.

I guess that is why you never see a black GX

I guess I should pay more attention to the F's and C's after the termperature. Thanks.

Just checked my figuers, and 102 deg C is about 215 deg F. This is in the temperature range the PRD (pressure relief device) will go off.

If it goes off you will know it! You will also have to replace the PRD since it a one time use device and probably the Cylinder valve (if Honda is using the GfI electronic cylinder valve.

Let's hope it never needs go off

They make black GX's. My friend has an 08 that is black, and I've seen a couple others around here too.
