Looks a little close to me. Did you use steel line? If you use copper it's quite easy to form it to stay where you put it, but even with the steel you might be able to get a bit more clearance. Although all it will do is warm the fuel, there isn't any way it's going to sever a steel line, although some heat will still be conducted into the rubber hoses. So I wouldn't say it's actually dangerous, but not ideal.
I was going to use copper, but the parts store near me had steel so I went with it. I had a little tube bender so I was able to bend the pipe. I had a tricky time getting the dimensions exactly like I wanted them which is why it's closer than I had intended. I don't think it's going to touch the manifold so hopefully it will just be a little warm. It's about a half inch to an inch off the the pipe.
I always thought you should mount a filter straight out of the tank, as it stops crud getting into your pump and your carb? any debris in your fuel is usually from the inside of your tank.
Yea, I would assume that any contaminants in my fuel are 95% of the time going to come from the tank, but this is an old Mini and the truth is that any part of the fuel system could be contaminating the fuel.
Your choke cable looks like it's resting on the manifold too 
Because my pump is in the boot, my fuel pipe now comes up from under the car to the bulkhead approximately where your pump is. The pipe then follows the bulkhead vertically upwards to a filter then around the back of the carb the to the carb float chamber. Could a similar setup work for you? I.e. route a solid pipe straight to the bulkhead then upwards even more towards where the wiper motor is? All depends on angles and clearances really.
Picture below shows a work in progress, but you get the idea.
If not, maybe try to get it routed so that it sits between the bulkhead and abutment plate to give it some shielding from the heat.

Kudos on an amazingly clean engine bay, My hope is that mine will look like yours some day. Clearly I've got a little ways to go.
Yes, my choke cable is currently touching the manifold and that is something else on my list of things to fix. I replaced the cable and then it touched and melted the plastic one day. You can actually see the melted section in the picture. I've yet to figure out a good way to keep the choke away from the manifold. I'll probably just zip tie it to another tube.
I suppose I could run a hard line straight up from the pump and put the filter to the right of the carb. Then have a flexible line running around to the left. Probably not the most elegant of solutions, but it would certainly keep the fuel away from the manifold. I wonder if there are any downsides to that.
