Ok guys for some reason my boost guage quit reading boost pressure the line is still attached but It's lke its frozen or something. I know my profile says georgia but i'm in pennsylvania for school at wyotech and its 25deg and snowing out right now.
So what would your suggestions be to find the problem and what should I do to avoid this problem again if it happens again? I have never lived in this cold of a climate so I'm not sure what effect it has on the boost line and how to keep it from happening any help will be greatly appreciated.

Hmm. air freeze? is that possible? i dont know man bad gauge or sensor maybe

25 degrees is not that bad.Unless you got some moisture in the line to the guage (maybe from your water-meth) and it has frozen it is probably the guage. Make sure you still have power to the guage as well.

boost line freeze?? never herd of that...like previous posts, check power, ground, and make sure the hose didn't get pinched or broken anywhere. 25 degrees, your fine. Its been in the single digits alot here recently, and i haven't plugged the truck in yet. when i went to school in maine for 5 years, it was constantly in the negative temps, and no problems with anything freezing. i have my boost line going through the steering linkage boot, and once when i was turning the wheel it got caught up and it broke the line.

It's been -20 here and i have never had a problem. Maybe you need a new line or gauge.

Well guys these are good suggestions but I have a mechanical guage not electric ground and power only go to lighting and that still works and the water meth is injected in the intake after the place where I tapped the bronze fitting in to read boost. The funny thing is it started working this afternoon and again the temp is still 25 deg and snowing outside I think it just had some moister in the line some where and it managed to thaw out from the engine heat so hopefully thats all it was. The line is routed where there is no possible way for it to be kinked or cut or broken
