Custom Made Fuel Lines

Why our Custom Fuel Lines?

RB Royal designs and builds flexible fuel lines ranging in diesel fuel injection lines, to custom made for your fuel lines. Considering the volatile nature of most fuels, sound design, and construction of components and systems by reliable, experienced professionals is essential to safe, trouble-free operation. Marine applications for fuel, as specified by the U.S. Coast Guard, require even greater fire protection. Assemblies can also be produced to meet Underwriters Laboratories approval. Because we produce many of our own machined assembly components, RB Royal can often be more responsive and cost-effective in developing and delivering solutions.

Flexible fuel lines utilize specially compounded hose to safely function with certain fuel types and blends as well as LPG and Natural Gas. Assemblies can consist of a flexible hose with end fittings or a combination “hybrid” assembly of flexible hose coupled with a section of bent and end-formed hard tubing. Hard lines are also an option in many fuel applications. RB Royal engineers will help design custom fuel lines from components best suited for each unique application and condition.

Frequently Asked Questions

What type of fuel lines do you do?

RB Royal provides gasoline, diesel, biodiesel, natural gas, and propane fuel lines.

What type of material do you use?

Fuel lines can generally be made from a flexible hose or hard tubing. They may also consist of a combination of the two – known as “hybrid” assemblies. RB Royal engineers will help design fuel lines from components best suited for each unique application and condition.

What is the lowest bend radius?

You do not want the bend radius to be less than 2x the diameter of the tube.

Can I have different bend radius’s?

We typically recommend using the same radius throughout means easier flow rate, programming, and quality checks.
