You don't necessarily have to remove the gas tank from your motor home. Your
Lazy Daze failed the LPFET (Low Pressure Fuel Evaporative Test), and
consequently the smog check, because the EVAP system was unable to hold
proper pressure; but where the leak is from needs to be determined. It may
be from the fuel tank and it may not. We recommend inspecting all hoses and
vacuum lines leading to the fuel tank, charcoal canister and between these
components and the engine, for leaks. Check for brittle, dry or cracked
hoses. Pay close attention near fittings with clamps. Over time clamps dig
into the rubber hoses severing them. With close inspect finding your Lazy
Daze Motorhome's EVAP leak found not be hard. Once the leak is found the
repair should be simply, and you'll be able to pass the smog test.
Having the EVAP test conducted with more gas in the fuel tank will make no
difference during the EVAP portion of the smog inspection. The EVAP machine
pressurizes the fuel tank as needed with Nitrogen gas. The less fuel in the
fuel tank the more nitrogen is added.
