Early 911 Fuel Line routing from tank?

[gper]

My 50+ years old fuel line from the tank fitting is leaking, they just don't make them like they used to, i guess.

I'm having trouble finding the "other end"

The tank end is obvious, but I can't see where it connects to the hard line running to the rear.

This is the outlet on the drivers side of the drain plug, assuming the opposite one goes to the gas heater.

Do you have the Factory Parts Manual (https://www.porsche.com/usa/accessoriesandservices/classic/genuineparts/originalpartscatalogue/)? It should show the parts you need.

[gper]

Yes, have both the parts manual and factory service manual, but neither shows much beyond a generic drawing.

I need to find where the hard line comes out of the tub

73 is the last model year that used steel fuel lines through the Tunnel.

This is a 73.5 911T with CIS....



The Earlier 73 model with carbs may have had only one Feed Line to the rear.

When upgrading to a later motor, I use METRIC Compression Rings to make a secure, High Pressure connection...



I specialize in 911 Fuel & Oil Hoses & Lines and would be happy to help.

This must be something unique to early cars. I finally found the end of the hard line. It's above the steering rack ! I took off the steering stabilizer and located the line up there, but had to take the gas tank out to get any view of the pipe end.

The issue is there is no clearance to get the new line pushed over the pipe end. The 2nd photo above shows the basic setup, you could probably get to the end of that without dismantling the car, but mine is probably 8" longer and follows the underside of the trunk above the steering rack.

I don't have enough clearance to get a pipe cutter in there to shorten it like the photo.

I'm afraid I'll have to drop the entire front suspension and steering to get this dumb 8" fuel line installed!

How can you expect anything rubber to last 50+ years, especially with today's gas running through it.

if you provide a photo it might help to determine what is needed to repair the leak.

Do we ever have to worry about those steel lines running through the tunnel failing and/or needing to be ditched in favor of the later style Carrera lines? Not even sure if that sort of retro-fit would be possible? I'm about to put a 3.2 into a '69E, the hard lines seem fine, but I've been running carbs and not the high-pressure fuel injection setup.

I was planning on using Len's fittings for all connections to those lines if I can indeed trust what's in the car now.

Obviously BoxsterGT missed the humor in my comment about the 50 year old fuel line. The only real surprise is that the line exists at all after 50 years (actually closer to 55).

I know what's needed to fix the issue, A magician with really tiny hands to attach it to the factory pipe.

After conferring with a couple of repair specialists they have two thoughts. Possibly a bent up pair of forceps that might provice suficient force to slide the hose on, or as I suspected drop the steering rack down enough to get access to it.

gper-

You are correct, I did miss the humor in your above comment.

I should lighten up. I get too serious about the fuel systems on these wonderful cars.

I have seen more than one being lost to fire.

They need to be kept for generations to come for all to enjoy.

Have a great Porsche day.

All good my friend, thanks for chiming in to help.

I'll check you out for some engine compartment lines, that's where the danger really lies on a carb car.
