308 Fuel filler hose

I decided to go do my fuel neck filler hose today and it took about 3 hrs. I had to slit the old hose to get it out. Once that was done I worked the neck out of the large rubber grommet. While in there I noticed this nipple that comes from the fuel filler area. This is the overflow in case you spill gas outside of the fill tube. I noticed that mine was plugged with crap so if I would have spilled gas it would run out over the body. Also this little nipple did not have a drain hose attached. Next there are 2 hoses coming off of the top filler neck. One is an overflow that runs out of the car and the other runs to a larger pipe that goes to the other tank. I look in my parts book and on the small hose it just shows it running down the tank with a rubber overflow hose. Parts book is a 75-76. On my 77 there is a check valve in this hose. That too was not operating. Based on how it was located it appears that it will let overfill fuel out and will not let air in or if pressure builds up in the tank it will vent. So these hoses will get replaced also. Attached are the pic's showing the old hose and the new one mounted. Not to bad of a job.

OK , don't own a boat but felt that double clamping was the way to go. So after removing the wheel and then the inner fender liner you need to remove the air duct for the oil cooler. If you loosen both clamps on the cooler duck and remove the bolt near the dizzy coils you can move the duct enough to take it out of the fender well. Next remove the filler neck hose clamps. I slit the hose to take it off. The replacement hose I got from NAPA and it is 2 1/8" ID hose. Next is cut the hose to the same length as the OEM hose. This is important or you will struggle to put it on if you make it to long. Next I pulled the filler neck down and toward the side of the car and removed it. I slid on the fuel hose and moved it down as far as possible on the gas tank neck. Use your finger and put some oil around the big rubber grommet where the filler neck goes. Push the neck up through the grommet and at the same time push on the rubber hose to collaps it. Push the filler neck up as far as possible and it should just clear the rubber hose. Line up the neck with the hose and fron the top push the neck down. Now take the big hose and move it around until it is centered between both the fill and the gas tank . Unscrew the band clamps and put them around the hose and tighten. Replace the 2 other hoses with the right size hoses and you are ready to put back the liner and wheel. You can do this on the floor or on a lift. I have a lift so I am sitting down when I do this.

The two white things in the picture are just a few dizzy rotors that I had on the bench when I took the picture. Good luck and have fun.
