new tank...jacked or what?

[complicationjack]

i have a new 68ci 4500psi crossfire tank and ever since i got it filled it has dropped psi...it was filled to 4500 and after it cooled down it dropped to about 4000...a couple days later the tank is reading 3500 then 3200...what the heck!? could it possibly be the gauge being broken in? or is my tank jacked?

Don't play with the tank. If it keeps dropping, see if it stops. If it doesn't stop, it must be leaking. If it is leaking, send it to Crossfire.
