Review on 🚗 Dorman 310-215 Evap System Integrity by Mike Bucher

Oe has a ribbed O-ring. The replaced block had a piston inside which, unlike this new block, moved very easily. Some extra pressure was required to install the assembly, due of course to the unworn o-ring. I had a p0456 on a 2010 t&c lx with a 3.8 liter V6 engine. Replaced the gas cap and the problem is less. evlp seemed to be the last piece. I don't think I would need to replace the underhood evaporator solenoid valve to fix the problem as the diaphragm has been known to fail in Chrysler.
