New Portable Fuel tank vent

My mechanic installed one with the new EPA system and cap and the pressure became too high. Any suggestions? Thanks Harvey edited subject for specificity Edited by Phil T on 08/03/16 - 10:05 AM

The vent is designed to open only when the pressure reaches more than 5 psi. Many owners have complained of the tank deforming due to pressure buildup. I personally found the new cap/vent led to fuel spilling out from too much pressure in the tank. Common suggestion is to replace the new cap/vent with the old style: https://www.amazon.com/Moeller-Tempo-...kgo-osx-20
