Matching fuel pump to injectors.
Hi guys,
When swapping from standard injectors to uprated ones - green or otherwise, at what point should you swap your fuel pump? Is there some way to work out what pump is best matched to the flow rates of the injectors being used? Sorry if this sounds silly, im not too up on how EFi works. If anybody knows some good reference sites that would also be handy!
Cheers!

on a escos, you need to get either the grpA one or the walbro like for like uprated replacement one as the escos std pump is the same as any other efi escort and just cant supply the fuel when bigger injectors are used. a saph can handle greens on its std pump , but if its never been replaced it will be getting slightly lower pressure than when new, so i would change it aswell
