TEST 22 -CHECK INSTALLATION
Does the installation include a second in-line fuel filter? If so,, check
the filter for clogging. If a shutoff valve is installed in the fuel
supply line, make sure the valve is open. Finally, make sure the air in­
let opening in the door is large enough. An insufficient supply of cool­
ing air will result in high compartment temperatures and possible fuel
line vapor lock. Refer to INSTALLATION MANUAL, RECREATIONAL VEHICLE ALT­
ERNATORS (Part No. 49204).
