decdd19 Posted December 27, 2015 Share Posted December 27, 2015 anyone used one of these on the vent pipe from the fuel tank in the engine bay for motorbikes but thought it might work the same maybe http://www.ebay.ie/itm/RFX-Fuel-Petrol-Tank-Gas-Cap-Vent-Tube-Breather-Pipe-One-Way-Valve-Gas-Gas-Red-/121538318929?hash=item1c4c3f9251:g:NpUAAOxy0bRTFd~6 Quote Link to post Share on other sites
Ep82gi Posted December 28, 2015 Share Posted December 28, 2015 I use to have one on my quad bike years ago it never stopped the smell just use to prevent me losing petrol if I flipped it. "Witch I did many times" Quote Link to post Share on other sites
TurboTobz Posted December 28, 2015 Share Posted December 28, 2015 (edited) Been used before, personally I just run a pipe to just beneath the car not had issues. But may not be the best idea. Edited December 28, 2015 by TurboTobz Quote Link to post Share on other sites
Cattanach Posted December 30, 2015 Share Posted December 30, 2015 I just run a pipe to the little black box attached to the inner wing!Been like that for months with no problems Quote Link to post Share on other sites
5e colin Posted December 30, 2015 Share Posted December 30, 2015 why not just block the vent altogether ?? Quote Link to post Share on other sites
daniel_g Posted December 30, 2015 Share Posted December 30, 2015 why not just block the vent altogether ??Because its ment to be a vent to release excess vapour in the fuel tank. Quote Link to post Share on other sites
5e colin Posted December 30, 2015 Share Posted December 30, 2015 does it any harm ??? because mine is blocked for the past 4 years never noticed any problems ( yet ) Quote Link to post Share on other sites
lukEp Posted December 31, 2015 Share Posted December 31, 2015 (edited) It'll cause vacuum in your tank if blocked off. If it's blocked off and you don't get a hissing/sucking noise when you undo your fuel cap then your fuel system isn't sealed. If you do get a hissing/sucking noise when you undo your fuel cap then your tank is vacuuming. Basically your fuel pump is sucking the fuel out the tank and air is supposed to replace that space but if air can't get in then your tank will vacuum and implode.
