Which gas line does the filter go on?

I installed a new fuel filter on my blower, now it wont run. I could not tell whether the fuel filter should be on the small/large tubing in that it had previously become unattached to the tubing. Does the filter go on the large/small tubing?



Hi John,

The gas filter should go on the small line only. The small line is the gas suction line from the tank supplying the engine. The large line is the gas return line from the engine back to the tank. Essentially the purpose of the gas filter is to protect the engine from particles and settlement coming from your gas tank, hence why it is attached to the small line. For an easy to use guide on replacing these gas lines and filter please see our how to guide below:
