That's what I thought when I said this:main pump: 135l/h (380kPa and 13V, 8A)
2nd pump in left half tank: 100l/h
(other S60's have 125l/h)
All pumps in Volvo's are a 255LPH pump to my understanding. The miss understanding from the LPH post of 135/100lph is that the pumps are regulated by the FPM in the trunk, near the spare tire. The pumps deliver LPH by how much amps they receive. At max input, the pump will deliver 255LPH. At 8A, the pump will only deliver 135LPH... and at 4A, the pump will deliver 100LPH. Combined total is 235LPH. The same pump is in a lot of Volvos and the LPH demand is regulated by the FPM Amps. I would think if you pulled out another mechanic book and looked up, lets say a S40, it would say 150LPH 13V @ 9A.255LPH on all Volvos
I think the car only pulls about 235LPH peak with 12 volts. Plenty for most people here.
