So Iv been reading 2 conflicting things on here about this pump and orbital fuel injection system.
#1 the comon consensus is that the fuel pump needs to produce and does produce 107+ psi. It's seen on the pressure gauge and the manual says that's what it should produce minimum. And that's why there is so much trouble finding aftermarket pumps for the DI ski's
#2 Now if you read up in a service manual about the orbital system it says that the pump will produce 27psi with the dsss plugged in. Than when the engine is fired up the compressor produces 80psi air pressure which in conjunction with the 27psi fuel pressure produces the total 107psi you see on the gauge when the engine is running.
Now what is it? Is the electric pump really only producing 27psi at all times? Can't be, guys on here have ran factory pumps in test set ups isolated from the engine and seen 147psi. 01 di fuel pump issues
So is the service manual bulshitting us? Or is this just a mystery some bombardier engineer only knows the answer to?
What do you guys know about this system, can anyone shed some light on this, or maybe I'm just missing something that's obvious.
