Fuel return line - 03 R6

I recently replaced my fuel pump on my 03 R6. After putting the tank back on the bike I noticed that there is a leak from the fuel return nipple. It appears it’s slightly loose. I took the tank off immediatly after just to be safe.

Question is whether this is normal and will automatically seal when It’s pressurized?

Thanks
 
Fuel leaks don't usually improve when you apply pressure to the fuel :|
 
I'd agree with above.

The hose may have degraded over time (it's 15 yrs old). Buy new rubbers!
 
btw: 2003 is pretty new to be needing a new fuel pump, the pump uses the fuel for cooling, keep more fuel in the tank and don't let it run so low and your fuel pumps will last a lot longer.
 
I'd kinda agree with you but I've owned a 03 r6 and always kept minimum fuel in tank as it has always been a race/tb.

Every once in awhile the 03-05 R6 ends up with a pump that is a turd. It happens.

Regardless this convo is not going to help OP with their issue, bottom line is rubber lines have prob degraded and need elasticity.
