Fuel Lines

If your motor home is older than 5 years, be sure to check the rubber fuel lines. These lines can deteriorate over time and become hard, cracked and easily broken under the pressure provided by the fuel pump. Diesel or gas, it doesn’t make any difference. Check to make sure that the fuel line is not rubbing against any engine component, especially the engine block where it could be subjected to heat from the engine. Rub the line to feel for soft spots or bubbles. If you rub the line and you get black rubber soot on your hands, it may be a sign that it is time to replace the line. The cure is rather inexpensive, compared to a potential fire or road side repair that may cost much more.

It is a good idea, as part of your routine maintenance, to check around the engine to see if fuel lines are leaking.
