How long do fuel relays last?

Fuel relays typically have a lifespan that can range from 10 to 15 years, depending on factors such as vehicle usage, environmental conditions, and the quality of the relay itself. Frequent cycling or exposure to extreme temperatures can shorten their lifespan. It's important to monitor for signs of failure, such as starting issues or fuel pump malfunctions, which may indicate the need for replacement. Regular maintenance can help extend the life of a fuel relay.
