Well, now hold the phone..... It depends on the barbs AND the hose used. I have used certain reinforced hoses and barbed fittings from NAPA for over 20 years for oil cooler and remote filter lines. If you get the right ones, they are heck to put on, and never come apart. I promise, you can tow a tank with it and it just might rip the threads out of the fittings before the hoses come off. I have puts thousands of rally race miles on this stuff and the recent 340 remote oil filter mounts was done with these.
