I switched the pumps on my setup from series to parallel as the Ellison
throttle body
on my Subaru setup only requires 3 psi. One big negative on two pumps in
series is that if
there is a blockage, both pumps are taken out. In the parallel arrangement,
if one pump
gets blocked, the other pump can still deliver fuel.
