Fuel lines

[Germy]

Quick question. Are fuel lines supposed to have some rubber joints or did my po kink lines and repair with hose?

The feed and return should be a solid line with hose only at the ends.

My 66 has joints in the fuel return line at about the middle of the driver side floorboard that look stock. The main line only at the fuel pump.

Yeah, fuel pump is rubber and some 90* rubber bends. Just thinking that since the motor is out, everything is exposed. Would be easier to run then now, brake lines too

Germy, I was under my '80 CJ7 yesterday installing a new grounding system. Each line coming from the gas tank is steel, but where ever the lines make a 90 degree bend in following the frame, there are short rubber hoses, maybe 2 to 4 inches long, connecting the longer steel runs. They look like OEM install to me in that each clamp is a spring steel "clip-on" clamp, not the screw-down SS clamps most after-market work uses.

If that is what you are asking about, we are both in the same boat. I could, of course, be mistaken about these being OEM; 32 years is a long time for a rubber hose full of volatile fuel to hang around.

Keep plugging away, and I will, too, after three years with this most enjoyable and challenging machine.

Yep, sounds like mine, not going to worry them!

There should be rubber lines connecting the tank to the supply and return lines. Then any time theres a change in mounting surfaces, ie from the frame to the motor. This allows for flex and movement. Then again from the pump over to the carb it's a hard line till the filter, since it will have movement. All the rubber segments should be short so theres no eventual collapsing and pinching of the line.
Then the same back to the tank, it's rubber from carb return line (hard) over to the canister, and rubber from there to the frame mounted hard lines.

Cool, what I figured,, just giving flex to the lines
