I found an apparently closed (invisible) crack in the rubber part (new) of the fuel line that feeds into my '65 Valiant fuel pump - very close to the pump clamp. (I only saw it when I pulled the hose off to check something.)

What effect on vehicle operation should this have had? I had just found the tank empty WAAAAY too soon (the car had been parked away from home the previous night, but I have a locking gas cap) but I don't see how the crack could even relate to that.

If the hole is lower the gas level in the tank, fuel would have found it's way out.............

... and it may not leak out when the car's parked. The geometry changes when the car is running, driving, braking, etc. That's probably why they used rubber, right?

Was that same batch of fuel line used elsewhere in the fuel system? You might want to check at the tank, filter, and carb. Leaks aren't fun. Fires are REALLY not fun.

If rubber line is leaking from the inside out something may of tore the inner layer, like the clamp too tight or the sharp tube it was slipped over.... Usually if it cracks from age or quality issues only the outer layer splits. Unles you used a hose not rated for fuel, and the fuel degraded the inner layer.

I've had cracked fuel lines with the outer layer severly cracked to the point you can see the inner layer - didn't leak one drop.

Same line used elsewhere? No, it was just a short, new piece between the steel line and the fuel pump.

As I said, the crack was right at the pump by the clamp. I'm pretty sure that's above the tank. Plus it's always parked slightly uphill and even more so this time. That's why it makes no sense to me that the tank emptied. And so suddenly. The only trouble I'd had before was junk in the gas stopping up the filter. (Gotta clean it up and put POR15 in it.)

And I'm just not that hard on fuel hoses. Finding a hose suddenly chewed up right at the pump connection makes me suspect foul play.

Thanks

How about the easy answer.............


Do you have a locking gas cap???????????






(never mind, missed the locking part before... ) (edited)
