Bad fuel hose?

Hi all,
Been awhile, I know.
I've been trying to get my J10 ready for some snow driving this winter, since I sold off my 4WD Toyota in exchange for a lighter, funner, more fuel-friendly 2WD 'yota truck.
The J10 hasn't been started in a year, and hasn't been driven regularly in about 6 years.
Anyway, the J10 wasn't starting due to lack of fuel. Replaced pump and filter, put fresh gas in the tank, still no go.
Dropped the tank, and found the problem: One of the rubber hoses that goes from the sending unit to the steel fuel lines had developed some serious cracks and then split. Here's the thing though - I had the tank out about 5 years ago, and replaced the hoses, and filter sock (in tank), and sending unit o-ring.
Is 5 or 6 years all I can expect from bulk fuel line? It was simple bulk fuel hose that you'd get at any auto parts store. Seems to me that the hose has lived a very short life before needing replacement. Is there any "better" hose that I can use?

You may have accidentally gotten the wrong hose. I once had "heater" hose used as a fuel line and it hardened like a rock and started to crack.

If they really sold you "fuel grade" hose rather than just rubber hose I'd say 5 years is not a common life span. I use bulk fuel hose from Napa on everything and never had an issue. Even the fuel hoses on my bikes that are subject to UV rays last over 5 years.

Well, it says "FUEL LINE 3/8" right on it.

My guess it was sitting on the shelf or in a warehouse a looong time before you got it. Rubber degrades in time . Hence the reason for DOT build dates on tires. I'd complain to your parts house, they may give you some more new old hose or change parts houses.

Sounds good - I'll just replace it and hopefully it will last a bit longer this time. Thanks for the help.

I have noticed that fuel line doesnt seam to last as long anymore. I think it may be these new fuel blends. My experience has been the hose getting soft and gummy not hard and brittle.

I've heard Ethanol wreaks havoc on fuel lines.
