I have an 07 650h1 and due to starting or lack of when the engine is hot I am considering changing the impulse pump to a low pressure electric. Has anyone considered this or am I looking down the wrong path ?

I have some pumps that are 2 to 4 psi. I still Havnt figured out what the pressure is or should be. Anyway my main concern is starting when hot and seems to break down around 3500 rpm under load . If I prime it when it's hot I have to remove the plug to clear the cylinder. I had a manual enrichment installed but the cable would pull out and flood the engine more. Any ideas ?
