How do temperature fluctuations in Pakistan affect the fuel system hoses and connections in BMW 2 Series?

I live in Islamabad where temperatures vary a lot between day and night. Could this cause fuel lines o r connectors on my BMW 2 Series to become loose o r crack over time? How can I prevent this?

In places like Islamabad, where temperatures can vary widely, the expansion and contraction of rubber and plastic fuel components can cause:

Hoses to become brittle and crack over time

Connectors and clamps to loosen, causing minor leaks o r vapor escape

These effects are worsened by exposure to harsh sunlight and poor quality fuel which can degrade rubber seals.
To prevent damage:

Inspect hoses and clamps every 20,000 km o r annually

Replace fuel hoses proactively after 5 years o r 100,000 km

Park in shade when possible to reduce heat stress on parts
