Anyway, yes, it is possible to force gas into the carb with too much pressure but worse, it could cause a leak into the engine oil pan to occur. In this hot weather the tank could create enough pressure to rupture the fuel pump diaphragm especially if it was aleady weak. As I mentioned in the other post, it could also lead to gas tank failure if the insides were already weakened from rust.

Thank You, I thought that it could happen but wasn't sure I seem to have a very rich condition and have had the carb rebuilt and still is the same, I also had the diaphragm in my fuel pump go bad. I moved the tank to the rear of the truck and went through the work of installing the canister venting and all of the lines, so I will go back to using the system. I would just use a vented cap but the way I had the filler door done it is very difficult to get a cap on and off so I went with the push access. I have a cover so the lines and filler neck are not exposed just have not installed it yet.
Thanks Again
