*Glenn* 854 Report post Posted November 26, 2009 (edited) No....venting only. And a cross over venting system between the two halves of the tank. Does the cap seal properly ?? Edited November 26, 2009 by *Glenn* Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted November 26, 2009 You'll need to remove the rear seat and take the inspection covers off to see if its from the top of the tank or not. Or raise it and check underneath... DONT SMOKE Quote Share this post Link to post Share on other sites
Mark 178 Report post Posted November 26, 2009 If you fill the tank up to the brim fuel can leak from a perished sender gauge. Lift up the rear seat and take a look as Glenn said. Quote Share this post Link to post Share on other sites
Matty104 0 Report post Posted November 27, 2009 Mine did this a while back, turn out to be the rubber 'o' ring arond the top of the intank fuel pump, $4 and it was fixed ( apart from the 20 litres of gas i lost because i had filled to the top of the long range fuel tank) Quote Share this post Link to post Share on other sites
