Most of my engine work requires the removal of the carburetor. Unfortunately, most of the fuel lines have no shutoff valve so a lot of gasoline gets spilled. I finally took the time to fix that problem. I hope my new tool will do the job.
I picked this up at CarQuest for less than $10. It is simply labeled a "Hose Pincher".
CarQuest model STL23000
Package says that it "Clamps and holds hoses up to 3/4""
