Problem with Drake fuel neck

[flatheadfan]

I installed a Drake fuel neck on my '36 and as fate would dictate the pipe did not line up with the fender hole. A careful comparison of the outside length of the Drake neck to an original found the lengths exactly the same. However, when you diagonally measure the distance from the cap opening to the tube end you find the Drake diagonal is 11" versus the original diagonal of 10". This difference suggests the bend of the Drake neck is different than an original which explains why it won't line-up with the fender hole. Has anyone else found this problem?
