Fule pipes

Sheathed fuel injection pipes

Hydrotest Systems is specialized in the development of sheathed and conventional fuel injection pipes for the marine, power generation and transportation industries. To comply with safety and environmental rules (such as SOLAS) Hydrotest Systems developed the high-end HYDROSAFE® sheathed systems with Lloyd’s approval. How does HYDROSAFE® work? The basics are simple. Leakage from the inner high-pressure pipe is collected by the outer pipe, detected and safely discharged.

In consultation with Lloyds Register of Shipping (LRS), the majority of our fuel lines are developed under Lloyds type approval. In case of special or different fuel lines, Lloyds will perform the inspection on site. Besides our high-quality standard, product fitment and easy assembly are of great importance.

Both standard fuel pipes and specials are manufactured or repaired for OEM, marine, automotive and offshore clients, even also for diesel specialists such as professional tractor pulling teams worldwide. Hydrotest Systems has long term experience in delivering fuel pipes on time and with the highest quality to suit the needs of major engine manufacturers.

Delivery on short term

We have created our own modern production line to be able to deliver products on short term for multiple engine manufactures and engine types. Fuel lines and supporting spray shields for several common rail systems are also available.

Hydrotest engineering


Using the latest state of the art CAD system and measuring systems our engineering team has the ability to produce solutions for new engines and older legacy engine designs. We can import from all popular file formats directly into our CAD system or record data direct from an engine or installation using our measuring equipment in the situation where drawings are not available. Hydrotest Systems can also help to offer SOLAS compliance and spare part support for older engines by either working from archive drawings or reverse engineering existing fuel pipes.
