1982 caddy fuel tank breather hose repair

Made early discovery that I was missing a fuel breather hose on the fuel filler neck on my 1982 caddy, whenever I filled my tank and discovered that fuel was dripping
from under the vehicle. 
Basic solution was to pay attention and when the fuel nozzle click off, STOP. 
However, sometimes I would forget and wind up pouring unburned fuel on the ground.

Finally decided to fix it. Stock fuel breather hose no longer available. 
OEM line had hardened and shrunk over the past 30 years and pulled away from the 1.5mm connection on the filler neck. Upon removal, found the hose contained a spring to keep it from collapsing. Split the hose and removed most of the spring (in two pieces) for later use. 

At the advice of Andrew, I set up a mcmasters account and purchased 24 inches of the hose 5/8 " I.D. and 13/16" O.D. Actually fit like a glove.

I drilled two (2) small holes at the upper end of the tygon and ran some waxed string to aid in pulling line upward over the filler tube breather connection. I placed the two pieces of spring into both ends of the tygon hose. 
 
I then crawled underneath and placed a 1.5L head bolt with washer into the tube between the inner and outer skin of the bed and braced it with a piece of wood. This allowed about an inch of the bolt to extend past the tube and allow the tygon hose to use it as a guide. After using a long screwdriver to help guide the hose into the tube. Then by removing the stick and head bolt, was able to feed the tygon under the the bed. 
Then I used the string and my left hand (only one I could get past the filler neck and was able to pull the string and guide the hose over the breather connection. I tied off the strings and went underneath, cut 6" off the tygon line and install onto the tank with a hose clamp.

Mcmaster has 5/8" ID and 13/16" OD tygon hose of the formulation I mentioned.

The passage between the panels is a tube a few inches long and has a I.D. of just less than an inch and can't be enlarged, unless I cut it off. Heating a piece of fuel line might just distort it too much.

Possible to enlarge the hole through the body?  (I am drawing a blank on what it looks like.)


Or possible to heat the fuel line you have found to be able to stretch it through the hole?

What is a good substitute for the plastic breather hose with spring that connects to the fuel tank and the filler neck.

Specs call for 15.5 mm I.D. and 2.5 mm walls. Everything I have found that is fuel resistant has walls that are too thick to go thru the hole in the body.

The old line had shrunk about 2 inches and was pulled off the filler neck. The original part number is 533 201 153 and is probably sold outside the U.S. Found same number for 1992 caddy in europe. All suggestions appreciated. ken
