Sunsong is a vertically integrated manufacturer that researches, develops and builds automotive fluid transfer hoses and lines. It designs its products around what the installer needs and works to exceed industry quality standards, delivering exact form, fit and function.
Signs a return line may need replacing include fluid seeping or dripping from the line, a reservoir level that keeps dropping, and a wet, cracked or damaged hose. If a leaking return line is the cause, this assembly replaces it. Diagnose the leak source first, because other steering components can leak too.
