Viva HB, vented or unvented fuel tank
Posted: Sat Apr 24, 2021 7:51 amAs the heading states, does the HB Viva have a vented or invented fuel cap fitted. I've fitted an ullnvented one on my project, will it need to be changed?

Would have thought all fuel tanks need to have a vent somewhere. Your sucking fuel out, air needs to get in to replace it.
