What's the highest fuel pressure you've seen run on a petrol road car at the FPR/in the hosing before being injected?

Thanks

Ah but diesels have a high pressure injector pump, but i would imagine the pressure before the pump in the hosing wouldn't be this pressure, maybe a bar or so more than a petrol though.

Is that 100 bar out the injector itself? As i'm talking about pressure in the hosing, not out the injector head.

Thanks

Most injectors like to see 3-3.5 bar static fuel pressure for the best spay patern but i have seen as much as 8bar total pressure.
