boost guage problem!

[palmyrasonlyMSP]

i just bought my mazdaspeed protege this week and it came with stewart warner digital tach and boost guage and the boost guage worked for like the first 3 days and all of a sudden it stopped working. if anyone can help me out here i dont know whats wrong. The tach still works it makes no sense. thanks

it was the vac line i put electrical tape around the boost line so it would fit tighter. thanks guys
