## Questions & Answers

**Q: what pump can i use with it ? can you give me the picture of the pump , thank you**
A: Try ones like this: Hopkins 10803 FloTool Transfer Pump. Takes 2 hands, but otherwise cheap and effective. Comes with a hose that connects directly without fittings.

**Q: What is the difference between the diesel and gasoline combustion gas tester fluid?**
A: Did not find that particular brand to work very well for diesel. Have used other brands which are combustion chamber leak detectors which work for both gas and diesel. The difference between a gas and diesel detector would be in the chemical formulation.

**Q: I don't have a radiator cap on my radiator So will it work on my overflow? Or what would you recommend**
A: Your  car has a degas bottle. Yeah it will work on that

**Q: Can it detect co2 in coolant? What is the average for success by testing?**
A: Yes, it tests for carbon dioxide and carbon monoxide in your coolant.
