My truck is in the shop for a bunch of gasket replacements and carb work. The mechanic said there is a problem with the carb in the form of a mashed tube as shown in the attached picture. I do not know what all the parts are in the carb so I can't name it for you but hopefully you knowledgeable folks will recognize it. Is this part pressed in and can it be changed - (it's the tube on the left)? I have another junk carb that might be able to provide a donor part. Any help would be appreciated!
