Fuel line help
I'm leaking fuel somewhere on the front passenger side. And I'm having some trouble finding the line that's leaking so I can take it off and have another one made.
Are there any rubber lines up front that could be it?

There are 2 hard lines that come up the right side into the engine bay, then 2 hoses up to the cam cover and then hard pipes again. If its one of these hoses DO NOT Drive it until fixed! They can spray directly onto the exhaust! Remove the air hose down the pax side to get a better view, and if that doesnt expose the leak, get underneath and check down lower. You may need to bridge the pump relay to produce the leak.
The top ends can be separated readily, but the lower connectors are a lot more difficult to get at. On my 83 Kjet the pressure hose was available a few years ago, but not the return hose. FWIW both my hoses were in excellent condition, no cracks or problems, despite 10 years in a hostile climate. If you get the hoses rebuilt make sure the builder knows they run at least 75psi.

I don't have the car at my house, I'll check it tomorrow.
Btw, does anyone no a good way to take off the metal lines. For example, I tried unscrewing one from the fuel distributor but the line twisted with the nut

Just did mine recently. And they were frozen on!
My solution was to use crowsfoot flare wrenches with a couple of extensions and a universal joint. I 'shocked' the joints initially with an electric impact 1/2" wrench. Broke them loose in a few seconds.
I had mine rebuilt at a local hydraulics shop. Cost $50 for both lines.

Are there any understandable diagrams of the fuel system?
You know, starting to lose patience with the fuel system. This car was left outside for twenty years. Before this car I had only worked on Hondas and toyotas, so I didn't know what to expect from a classic German car I dropped the fuel tank before I started the car. Then replaced the fuel pumps and filter. Turned the key. it started then a line busted, fixed it, another line busted, now this is.
I just want to replace all of them at once.
