Vehicle engine systems and protectors for such systems are presented. Vehicle engine systems can include one or more engine components associated with an engine. In some embodiments a protector can be attached to an engine system to substantially cover a portion of one or more engine components. The protector can have a shield and a support. In some arrangements, the shield can be operatively connected to two cylinder banks of an engine. The shield can extend over and substantially cover a portion of a fuel line and/or a fuel line connector. In one or more embodiments, the support can include a support end configured to support a vehicle component such as a throttle body.
