Vent and return go to the fuel tank right next to the feed on the sender assembly.

I don't know if your's is the same as my 78, but mine has rubber hose connections above the axle. If your lines are OK from there back, you could just leave them and get new pieces of rubber hose. My feed is 3/8, my vent line is 5/16", and my return is 1/4" I think. (your vent should go to the charcoal canister) You can see where I added a fuel filter in the pic (for an electric fuel pump). Other that that I can't help, cuz my system is totally different, with the feed on the driver side.
