Your car is old, and how sketchy old cars are.
So I have been looking into replacing my assorted brake/fuel lines, because my car is old. It looks like I had no idea what that really meant.
I am used to cars that are fuel injected, and require all kinds of special consideration to PSI and fittings and such. The Trans am? Rubber hose and squeeze clamps. Yeah. also, rubber hose that isn’t rated for ethanol in gas.
Now, I want to do this properly, for obvious reasons. This made vastly simpler, sure. Doesn’t make me feel any better.
interesting things to note: under the car the fuel line looks great. looks like the brake line shielded it from any corrosion. I won’t need to buy enough line to justify buying a 25' roll, so it looks like I will be buying whatever material the local auto parts store carries and never looking back. Nylon for sure for the vapor return, since it is both unnecessary and carbureted. But I am having difficulty with what kind of fittings I should use. I guess I cant just use hose clamps? Also, now I have a spot for my inline fuel filter.
I actually do think it was sitting in a field now, maybe some tall grass given the pattern and type of rust.

What’s wrong with hose clamps?

the possibility of fuel leaks right by my exhaust.

If you’re not running some fancy AN line, w hat would you use other than hose clamps?
I like fuel injection- style hose clamps for everything because they don’t chew into the line.
You could also just run fuel injection hose now. You never know what the future will bring.

Im using hose clamps for the regular fuel line. I don’t know if you can use them for the nylon line. Can’t find any info. Most talk about those plastic quick disconnects you have to heat in.

Ohh, I see now. Why bother with the plastic line ? Fuel line is cheap, just use more of it for the vapor line. Less likely to kink, less likely to break, same clamps for both lines, etc.

two different diameters, nylon requires zero bending. It’s also the fuel return, so it’s not critical to the car. Vastly cheaper, vastly less time invested. My actual fuel line will be proper metal and hose. Nylon is used on newer cars so for this borderline unnecessary tube it should be fine.

Is there some kind of in-between with a carburetor ? I thought you either ran it return-less or not. The former being more common on older cars with mechanical pumps but runs the risk of vapor lock. If it’s a return, wouldn’t it have fuel? Your photo examples look like the exact same size line for what I’m assuming is the feed and return. So why not just use rubber fuel line. It’s a buck and change per foot.

You aren’t supposed to run rubber hose for any real length. rubber is also alot more sensitive to puncture and you don’t want it along the underbody. the section where it is is fine.
My car has provisions for a return. the lines were rusted through and they are just blocked off right now. They are 5/16 where my fuel line is 3/8ths. It does have fuel, just not very much. No real pressure. Also, if it leaks for any reason it will leak on the ground, not in my engine bay.
