Installing new fuel lines isn't just about connecting Point A to Point B—it’s about safeguarding your entire system from heat, vibration, and abrasion. The routing of your lines is just as important as the quality of the materials you use. We want to avoid future problems!
Never let a fuel line touch an exhaust component. Heat is the enemy. It causes vapor lock (stalling) and, crucially, prematurely degrades rubber lines, leading to leaks. Always maintain a minimum safe distance or, if a close proximity is unavoidable, install a proper heat shield.
Use original-style clamps and fasteners to secure the lines to the frame. The last thing you want is a line vibrating against a sharp metal edge as you drive down the road, which can rub a hole straight through it! This is especially important for anyone doing classic camper repair Michigan style, where rough roads can really put a strain on components.
Pay close attention to where the line passes through or around frame rails. Use rubber grommets or specialized clamps to cushion the line and prevent metal-on-metal contact. And here's a pro tip: avoid sharp bends. A tight bend can restrict fuel flow and cause a weak spot where the line is more likely to crack under vibration or pressure.
Use smooth, generous curves. If you’re using flexible rubber hose, limit the length as much as possible, using it only for components that move (like connecting to the engine block or fuel pump) or for short transition sections. Hard lines are safer and more durable for the long runs. Once everything is connected and secured, give the lines a firm tug to ensure they aren't going anywhere. Security equals safety!
In this guide, we have discussed the critical steps of proper fuel line routing and securing them away from heat and abrasion points to ensure long-term safety and performance.
