midnightmoonlight Posted October 11, 2007 Share Posted October 11, 2007 The Jaz Fuel cells have a one way check valve vent in the cap of the fuel cell. I have a Harwood cell thats the same. It lets air out if the tank expands. The way Im understanding it is I still need a vent line to let air in correct? Quote Link to comment Share on other sites More sharing options...

It needs to be routed to somewhere outside the car and away from exhaust, other hot things, sparks, etc. It only shuts off when the car rolls upside down.

midnightmoonlight Posted October 21, 2007 Author Share Posted October 21, 2007 I understand the roll over valve/vent line. My question is the valve on the cell cap that lets air out and has no provision for a line Quote Link to comment Share on other sites More sharing options...

My question is the valve on the cell cap that lets air out and has no provision for a line Oh, I see. Assuming the roll over valve/vent is working properly there should not be a case where the cell expands and pops the check valve open except in fault conditions. I'd look at routing it anyways, though. Quote Link to comment Share on other sites More sharing options...
