Getting familiar with the group...
I drive a 2013 R-spec and have noticed that the right (passenger side) high pressure fuel pump is somewhat louder than the one on the left. You can actually feel the vibration in the high pressure fuel line, but, I don't notice the same vibration at idle on the left one.
I viewed the video posted by "home of stone" explaining the operation of the 5.0 Tau engine and the video indicated only one pump is used at low engine loads and was wondering if anyone had anymore info regarding this? Does the right one run all the time and the left one is actuated upon increased load?
I realize they are driven from the camshafts and I assume the control valve on each pump opens and closes to vary the amount of fuel that may be supplied to the pump and thus to the fuel rail.
Has anyone noticed that their right pump is louder (at idle) than the left one?
Sorry about the long rambling -- just wanted to hear your observations and additional info.
Thanks so much in advance.
