Rosebud tip makes a flame about the thickness of your finger, and if you brushed it across a pump panel it would probably blow a hole thru it. Can heat a chevy truck frame hot enough to bend it in about 3 min I think. In other words a "REAL MANS"Torch tip, which has no place in pump disassembly, maybe good on a cat or loader . You want a small tip, smaller the better, will get a screw head hot in about 5 seconds, with a flame the size of a matchstick.
Be worth it to load up your pump if you had to and take it to get it done. Usually it will expand and contract the fastener and then it lets go. Some call it the HOT WRENCH . If someone lit a rosebud behind you, you would know it and feel the heat from 3 ft away.............dodogas
