hi, i have a 4500psi evil tank and it is losing pressure through the gauge rapidly (about 200 psi in 2 hours). now if i put my finger over the gauge the relase of air stops. but threre is this little hole on top of the guage not sure what it is but when covered the sound stops. not sure what to do. it is defiantly there as have tried putting it under water.
