What is the correct slope for fuel-oil piping?

• A. At least 1/4 inch per foot towards the tank
• B. At least 1/8 inch per foot away from the tank
• C. At least 1/16 inch per foot towards the tank
• D. No slope is required

Answer: (B)

The correct slope for fuel-oil piping is essential for ensuring proper drainage and preventing any potential issues with fuel settling or creating blockages. A slope of at least 1/8 inch per foot away from the tank is recommended. This slope facilitates the movement of any condensation or spills back towards the tank, preventing fuel from pooling in the piping system, which could lead to corrosion or contamination of the fuel. Maintaining this slope ensures that the system remains efficient and reduces the risk of maintenance issues, such as the buildup of sediment or the creation of air pockets that could impede fuel flow. This is particularly important in systems where fuel must be delivered consistently and safely without causing operational problems. In contrast, other slope options either do not promote this essential drainage (like a slope towards the tank) or suggest no slope at all, which would lead to serious operational risks.
