Fuel System Installation:
1.
Run two minimum of ¼ inch fuel lines from the fuel
tank/fuel pick-up to the Aqua-Hot.
Both fuel lines should be laid as flat as possible and any
extreme rises in height should be avoided in order to
eliminate any potential air-traps.
Run both fuel lines in areas where they cannot be
pinched, kinked, or damaged during normal operating
conditions.
2.. Be sure to secure all fuel lines where necessary and
apply protective shielding in areas where chafing may
occur.
