My installation has the two pumps in parallel. Either pump gives me a
pressure of 40 psi.  When I switch both pumps I get a pressure of 55
psi.  That pressure difference would affect fuel flow at the injectors.
I do not know if it is a good thing of not. because of the pressure
difference I plan on using one pump only at a time.
