For the racer that is looking for the clean and tight look of stainless port lines RBS offers line kits for most popular engines. Each line kit includes eight pre-bent lines with black anodized alum. -3 lines nuts and tube sleeves. Designed to work with Enderle port nozzle blocks. Racer must specify motor type and deck height when ordering and if a large blower set back is being used we will have to get some measurements to make sure the lines will fit properly.
