[QUOTE="badcobra, post: 16621433, member: 20798"] I think I know what you mean here, but it wasn't stated correctly. Pumps flow more fuel volume at lower pressure than they do at higher pressure. If you are tight on fuel pump capacity, starting with a lower base pressure will give you more headroom on volume. If you are tight on fuel injector capacity, a higher base will deliver more fuel through the injector. So depending on your situation, it changes how you approach this. If you need more base pressure to accommodate smaller injectors you should plan to run the Walbro 274 high pressure pumps. This link is a pretty good test and explanation on pumps.
