I have issues with pumping my gas and the pump stopping too. It doesn't happen every time and it definitely is not worth $435 to fix. The canisters are up to $350 on FCP and the leak detection pump is $85. No codes here though. Would there be any repercussions in not replacing these items?

I also changed the leak detection pump as well, FYI.
Some mentioned canister fix is to thump it on the ground to break up the particles inside.
