Question 1 of 27070

Failure of the fuel oil service pump to maintain fuel oil flow to the burner could be caused by __________.

🔍 Key Concepts

• How fuel oil is filtered before reaching the burner • Typical symptoms and causes of restricted fuel flow in a fuel oil system • The effect of pressure settings versus physical blockages in a piping system

💭 Think About

• Which of these choices would physically reduce or block the flow of fuel oil going toward the burner? • Which options would tend to increase system pressure or flow rather than reduce it? • Think about what happens if filters or strainers in any fluid system are not cleaned regularly.

✅ Before You Answer

• Identify which component in the list is specifically designed to remove contaminants from fuel • Ask whether each option would most likely restrict flow or increase pressure/flow • Consider common real-life maintenance issues that cause fuel starvation at the burner
