    When filling my truck (2014 Tundra), especially on warmer temperature days, I open the fuel cap and theres a release of pressure. Then, I fill from pump and it takes much longer than normal to fill as a pressure/air hole appears to be blocked . This must be a common problem.

    Anyone who can provide a link to thread where this has been discussed, is 100% appreciated!!!

    Yep, there is a information here about a check valve at the base of the neck. You have a problem. This is why I don't fill my tank full.

    I've never had pressure on my tank and have had roll over valve issue that I've commented on. There is a vent line going to carbon canister that is behind rear of fuel tank just in front of differential, you can disconnect the large line going to canister blow air thru fill tube to make certain line is clear. Then blow in canister to make certain it's open to atmosphere that will vent near the fill tube to tank. If all that's clear I'm at a loss to your pressure problem.
