If you run gasoline through a diesel-rated hose and vice versa, that's the result.

Interesting that both of the clear hoses you linked say not intended for use with diesel fuel.

all the black fuel hose if fuel rated, is good for gas or diesel.

“When ordering parts online, always call the seller to confirm the part is exactly what you need. In the hose category—whether from NAPA or any other supplier—there are multiple types of fuel line for both gasoline and diesel. A quick phone call lets the seller verify the exact hose you’re referring to, eliminating any confusion or doubt.”

You are the first person that I have ever heard say anything about gas specific or diesel specific hose From the research I have done, and personally seen, biodiesel needs a specific hose,, but every fuel hose I have been able to find is rated for gas or diesel.

Can you provide some examples, I am genuinely curious as I do lots of work with diesel stuff and have used regular fuel hose with no issues. But if there is a better way, I am all for it.
