so i bought this 13ci tank off rocztar a lil while ago and used this tank a few times
and the other day i got it filled and buddy says the gauge was screwed up
but wont effect anything other then see how much it gets filled
but i got it filled at 1:00pm
and by 6pm that night it dropped almost 2000psi
there is no leak that i can find or hear

any ideas?

id say just change out your gauge and see how that works, there may a tiny leak 2 where u lose pressure through out the day, if im wrong i am sorry,

no worries
i think i might have to get a new gauge thanks for
your 2cnts


also a lil green to start you off

I doubt the gauge is your problem.

Fill the tank to 3k, and let it sit for a week. If, by the end of the week, it is still holding air then it is definitely not a leak. I'd be willing to bet that your pressure drop is simply from a hot fill, nothing more.

what do u mean by a hot fill

did you read the OP?

i got it filled at 3000psi at 1 oclock and by 5pm it was just above empty

so there is a leak just dont know where

when you fill a tank it will be warm as it cools down to room temp
it loose a bit of pressure
