The secret to success with the 340 Stealth Pump and carbureted engines is to select the proper carbureted bypass regulator, Aeromotive recommends P/N 13204, and to install a large enough return line, or AN-08 from the regulator back into the top of the fuel tank, in order for the regulator to work properly. So, just comparing these 2 pumps, you can see one of them falls off pretty drastically as fuel pressure increases, while the other one maintains flow better at higher fuel pressure. Installation of a fuel pump like the 340 Stealth into todays returnless systems, when you consider that it flows 2-3 times as much volume, draws 2-3 times as much current and is not necessarily the exact size and configuration of the pump it replaces, will very probably throw the OEM fuel system substantially out of balance, and if run for any length of time, may very well damage either the fuel system components or the 340 Stealth Pump itself. The 450 High-pressure will hold steady pressure until 110psi before it bleeds off. This is an intentional step in our methodical interpeting of the test results, to avoid contamination from any potential preconceived bias that may sneak in from personal preference. This is due to the fact that the pump DOES flow 525lph, but at a very low pressure that will honestly never be seen in a performance application, as such its known as the 470lph due to the fact that it actually flows 470lph @ 50psi, making the comparisons fair.
