Here's why:
* Older Vehicles: In older vehicles, fuel filters were generally placed upstream of the carburetor to protect it from contaminants.
* Engine Design: The 460 engine is a carburetor-equipped engine, and the fuel filter would need to be placed before the carburetor to effectively filter the fuel.
* Dual Tanks: With dual tanks, the fuel lines would likely merge into a single line before reaching the fuel filter and then the carburetor.
However, without a specific model and year of your motorhome, it's impossible to be 100% certain.
To confirm, I recommend:
1. Consult Your Owner's Manual: This is the most reliable source of information for your specific vehicle.
2. Look for the Filter: Look for a cylindrical metal or plastic canister with fuel lines connected to it. It's often located in the engine compartment near the fuel lines.
3. Consult a Mechanic: If you can't find the filter yourself, a mechanic can easily locate it for you.
Remember, regular fuel filter maintenance is essential for the health of your engine. A clogged filter can lead to poor fuel flow, engine performance issues, and even engine damage.
