Fuel psi. ?

[Bobs rare 6]

If running a double pumper with just one pump hooked up, would ther be a few psi. drop in fuel under boost? Wonderd if it can back bleed through other pump. Thanks, Bob.

Sure it is possible. Check valves are not 100%.

when the boost equals the turn on point of th 2nd pump then there is now way for a pressure drop. But before the required boost it might be possible, but not much I would imagine.
