It looks like rubber hose in your shopping bag. At least it is easier to get to your pump now. Me and others have only had luck, I mean a permanent fix, with OEM type corrugated nylon fuel pump hose. It's a pain to install, I am glad I bought more than one. It needs to be warmed to get over the fittings, but there's a narrow temperature window between softening and melting. I found that boiling water isn't hot enough, and a heat gun is too hot. I ended up heating vegetable oil on the stove to a certain temperature and holding the end of the hose in it long enough to reach that temperature. It also lubricates the hose during installation. I am sorry that I don't remember the exact temperature, I think it was 300°.

I went into such detail because I feel like I failed you by not saying to use the corrugated nylon, instead of only saying that any kind of rubber hose will fail.

I appreciate your input. I agree that that corrugated hose is the absolute certain fix. The rubber hose I installed is not only fuel injection rated, but also rated for submersible applications which means it will last much longer than the one that came with the pump. With that being said, I still plan on installing the corrugated hose this winter to totally avoid any future issues. Hopefully this post helps someone out in the future!
