powerdyne 200lph inline pump

Does this inline pump return to the other
tank? I have a BBK boost pump and it returns
into the secondary tank.Anyone else have this
problem? is it just better to get a relay kit
from SAL at psp and how well does it work?

Eric, whenever you boost your fuel pressure over the set regulator or FMU you risk return to the other tank. It is a well known quirk with these trucks. The secret is not to actuate the inline until you actually need it through a hobbs switch. You can get a hobbs to turn on the pump through a relay say at manifold vacuum of 2" for normally aspirated or nitrous or 2lbs of boost for blown applications
Hope this helps
