  • PRO GRADE: trusted by the professionals
  • SIMPLIFIES REPAIRS, MAGNIFIES MUSCLE: gives you all the leverage you need for those stubborn jobs

Can't heat gas line

5 days ago
This from over 10 years ago. I had an 86 Astro van that the hose from the engine to the rail back to the gas tank developed a pin hole leak spraying next to the running engine. I spayed the connections to the engine and the rail. I waited a few hours and the both broke loose withou any problems. A few weeks latter I got an oxygen sensor replayed at a garage. Asked them what the would of charged to replace hose. Thwy said they wouldn't try because the rail would have needed replaced also.
