Re: Location of Gar ber fuel filter for hurricane hydrohot

You could have air in the fuel line. On my Hurricane, there is small valve on the top of the unit that allows unused fuel to return to the tank. You can crack that valve slightly to allow any air trapped in the fuel line to escape and be bled back to the fuel tank.
My furnace has an inline fuel filter on the fuel line coming to the tank. It is similar to the one you describe. There is an internal filter that should be changed on an annual basis when the annual maintenance is done.
