i have an issue with random knocking sound from the fuelrail when the car is idling and it seems to be happinging when i rev as well. I can physically feel it in the rail, but no other place on the engine. FPR is mounted 5-10 cm lower on the firewall, but i cant really feel it there.
when the knock sound occur, i get a 10% ish rich spike afterwards, but i cant see any change in fuel pressure.
i do not have a non-return valve, so i tried just running the pump for a while before starting, which seemed to help a bit, but really har du say really.
i saw that my injector dead time was a bit out and have adjusted these now, but not been able to test afterwards.
im guessing this might be air related, but i've optimized the routing with no luck. i've also pulled the plug on each injector and the issue persist.
im also using a 044 pump and have heard that they might cavitate, and the sounds might resemble an hydraulic hammer.
im using emu black v3, 044 pump, and old unused aeromotive fpr that i have had laying around for 15? years.
any tips and pointers would be much appriciated
borrow a pump n reg off a mate n see? just to check.
Fit a Pulsation damper.
Have you considered that it might be one of the Injectors malfunctioning?
