Now with the great smell of petrol

have a look at the rubber pipes that connect to the injectors try tightning them up as they crack on the inside.

the reason you can see anything when its hot is because the fuel is evaporated straight away

Would it be best to replace them if they were cracked? Or is that a test to see if they need replacing?

I had a sniff around, and could smell nothing straight after driving it. I will try it with the engine running. Didn't really want to stick my head in there with petrol squirting about. (what psi is petrol pumped up to in the engine to inject it?)

about 40 psi

I had exactly the same thing with a Peugeot 205

Going along fine, but come to a halt and the fumes were over powering!

Turned out to be a split in a rubber hose from the fuel pump to the carb

When going along the carb's demand for fuel matched the pump's output but when at idle the excess pressure was too much and it was spraying onto a hot manifold

I changed that pipe very soon afterwards!

OK, had a look with the engine running, but the engine was cold. Did not see any hot 40psi jets of petrol death, so I stuck my head under, and there was no smell. I think I found a rubber pipe that feeds the injector rail (may be something else though) it has a metal part built onto the end of it, and is connected to the next bit with a nut. No squirts or wetness.

All I could find is that the breather hose at the top of the engine was split (been cleaned that many times, the plier clip thing looks to have chewed it up), and a brown liquid has been evaporating off a little shelf below the front / bottom end of the pipe. I was going to replace this pipe anyway, cos it is soft and sticky on the inside

So, could the split breather pipe be letting petrol smells out (definitely petrol, not oily smell), and does the "only when hot" back this up?

Thanks

Filling up the other day, I noticed that the smell of petrol is slightly different from the smell I am getting. I now think the smell is a bit petroly, but exhausty too.

I put some duct tape on the split pipe as a temporary measure while the new pipe arrives, and the smell seems to have reduced.

I will have another look at the injector rail too.

If internally cracked I find that tightening the clamp usually makes the leak worse. If you can prove the leak best replace the hose or, if there is sufficient slack, lop off a half inch from the end.

If it's squirting about that much you should be able to spot the leak.

Don't know the exact figure for your engine but enough to get you wet. The pressure can be held for a good while after the engine is last run. Some cars have a depressurisation valve but you would need to check your manual for that. If I need to break into an injection supply I pull the fuel pump fuse and then run the engine till it cuts.
