When was the last time you replaced ALL your fuel hoses?, How long has it been?! Options

[VaccaRabite]

Over the past few weeks I've been replacing my fuel hoses.

Well, it started 2 years ago when I put in the new engine, I decided it was a good idea to replace all the engine bay fuel lines, even though the hoses there had "just been replaced".

While doing my brake master earlier this month I chose to pull the gas tank and just do the res hoses on my work bench. Which exposed all my under tank gas lines. Those are still new, right? I replaced those not long ago. 2014? Oh crap those are 10 years old.

And what does "new" gas line look like? Mostly fine, except where it had dry-rotted and was weeping fuel. And this was not cheap hose. This was expensive Continental SAE 30r9 injection hose.

So I replaced it all. Put the tank back in. Backed the car out into the drive way and just let it idle while I looked for leaks. Found a leak under the engine bay. I forgot about the hoses that went from the center tunnel to the engine compartment hard lines. And while wiggling my tunnel hard line I had opened up a dry rot crack. So I got more 30r9 fuel line and replaced those lines. Now I'm leak free.

I bet a LOT OF YOU have fuel lines older then a decade. If you aren't sure, then its time. Replace your fuel lines! Fire is BAD.

So what is the recommended life of Gates barricade fuel injection hose?

According to their documentation, shelf life is 3-5 years so don't buy more than you need. There is no specific info on when lines should be replaced after they've been put into use given the numerous variables.
Personally, I wouldn't go longer than 5-7 years. Fuel hose has gotten expensive, but replacing the fuel lines is still a lot cheaper than replacing the whole car.
