87 Tank in a 75. Filler hose options?

[kdh454]

I'm getting close to finishing my EFI conversion and have swapped out my '75 tanks for '87 TBI tanks in order to use in-tank pumps. All was good until I noticed that the '87 tanks accept 1 3/4" filler hoses where my '75 was 1 3/8". Obviously, my new 1 3/8" hoses are not going to stretch over a 1 3/4" barb, so what are my options?

I've found a 1 3/4" 90 degree elbow (Gates 24716), with which I could use a short piece of 1 3/8" tubing as a reducer if the OD is close enough. Is that really my only option?

I doubt I'm going to find a molded hose that fits perfectly, but hopefully someone here has ran into this before and has a solution!
