Aero Z Posted August 18, 2011 Share Posted August 18, 2011 (edited) On my LS1 swap I have done the typical mounting of the (02) plastic camaro tank and use the integrated pump and sender just like the stock camaro setup uses. Also using the C5 filter and return line commonly done. Have wired up the sender and pump fine but am wondering what others have done with their charcoal canister and vent lines coming off the tank? Right now I just left those parts as is and it works fine but a couple times filling up I notice a gas vapor smell. Not sure if this is just gas slosh coming up the vent line or what. I believe I have capped off the stock LS1 gas vapor recirc thing on the engine and the smell seems to be coming from the tank area rather than the engine itself. I've searched (and copied others) installs of their Camaro tanks but can't find a good answer on what has been done with the charcoal canister and vent line routing. Pic for reference. Just FYI and not my setup exactly. picture Edited August 18, 2011 by Aero Z Quote Link to comment Share on other sites More sharing options...

smoorenc Posted July 5, 2012 Share Posted July 5, 2012 Cable, How is the check valve holding up? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted July 6, 2012 Share Posted July 6, 2012 Which way would you have the check valve working? I would think that you want air to enter the tank as fuel is consumed or as the temperature drops and that you would want air to escape as the tank fills or the temperature rises.

Cable Posted July 6, 2012 Share Posted July 6, 2012 (edited) I have mine set to allow air to escape when filling the tank with fuel. Otherwise you'll be standing there all day trying to put fuel in and the pump stopping every few seconds because of the back pressure its seeing.

smoorenc Posted July 6, 2012 Share Posted July 6, 2012 Thanks Cable, Where did you mount your check valve? After the charcoal canister? Quote Link to comment Share on other sites More sharing options...
Cable Posted July 6, 2012 Share Posted July 6, 2012 (edited) I ditched the charcoal canster altogether. My check valve is installed on the same 5/16" port in your picture marked 'vent'. Edited July 6, 2012 by Cable Quote Link to comment Share on other sites More sharing options...
