Replacing the gas tank on my 1989 Bronco. When we tried to pull off the plastic fitting that connects the gas line to the fuel pump, it broke off in the hose. We have another one from the new tank, but we can't get it in the line. We've been heating it up with a hair dryer and 100w work light :toothless Its going very slowly and we can't get it over the second nipple without overheating the gas line. Any suggestions?
