Need more symptoms of your issue to help.
Hard to even tell it's a torch in the picture.
Where is it leaking?
Do you release the air before refilling?
The port should be depressed until the hissing sound stops before re fueling.
Does the torch have an air adjust valve?
Help us help you.
My best advice..
Go on line and get a free e 20% off coupon for Bed Bath and Beyond
Go to store and buy the Bonjour creme brûlée torch (There is large and small version)
Same exact thing as the 70$ Vector torch, but for 25$ish .
