It's the material of the original hose that is terrible. If you have the soft rubber original hose then do yourself a favor and get it out. I've been running the hardened version (I think it was one Rob Grady sold but I can't remember) of the pump to pickup hose for a decade and it has been trouble free. The biggest issue I ever have is the damn fuel pump boot breaking down with today's ethanol fuel. I bought one new and it lasted less than a week, I bought another used here on the forum and it's lasted years and still going so it's really a crapshoot.

Not the best design, agreed, but I'm also not sold on the all-in-one units yet.
