I'm stuck here with this fuelling problem.
From cold everything's fine, once it heats up it goes suddenly dead lean (to the point it runs rough and dies eventually)
I did find a seriously kinked fuel hose, from Lager's FPR to the back. I fitted a longer one that has no kink. Nothing.
I changed the o-rings in the pintle caps of the injectors (reds). Nothing.
To complicate matters, if I only use extremely light throttle from the beginning it doesn't do it at all. Only plays tricks when engine is warm, but sometimes it starts when the temp is 93, sometimes 90, sometimes below that.
