Wealth of Experience, Pride in workmanship


"Men at Work"

Regular engine service & maintenance protects the longevity of any engine. As a result of extensive training at the Gardner factory in the UK, Mainline has the experience to provide a high quality service level to all customers.

In-House diagnostics:

As well as full or partial engine reconditioning Mainline's in-house diagnostics include repairs to Gardner fuel pump assemblies, fuel lift pumps, water pumps and sub-assemblies. Specialty equipment and tooling is extensive and includes an original Gardner fuel pump calibrating machine, enhanced by modern electronic controls, that calibrates fuel pumps exactly to original Gardner factory specifications. Contact us to obtain prices and information about the fast & economical Gardner Service Exchange Parts programme (GARDFAST) for many reconditioned sub-assemblies. OVERNIGHT deliveries within major areas of Australia and EXPORT arrangements are a priority.


"A correctly maintained fuel pump system plays a crucial role in an efficient and cost effectively run engine."

On-Site diagnostics:

Mainline's on-site diagnostics include general engine service & repairs, cooling system design & fit out and "in-situ" top end overhauls where practicable. Contact us to discuss your service and engine maintenance requirements; travel to all areas can be arranged.
