57 Eldorado - Gas filler tube proximity to exhaust pipe - cause for concern ?

[Acmemopars]

Hello

I have a 57 Eldorado Seville (stock 365ci 2x4)
I installed a new gas tank and filler tube during the restoration (ongoing)...

I'm just now breaking the new engine in and while at the muffler shop earlier today, I noticed that the exhaust will nearly "touch" the gas filler tube if ran out the rear bumper like it should be.

Is this normal ?
Any cause for concern ?

Thanks in advance for any help.

This may or may not be an issue, just checking to see if anyone else has ran into this ?

Thanks in advance
Mike
