The only cars I saw them on were V8's.. One was a suburban and the other was a truck with a 460 and an edelbrock EFI system... .None of which were real beastly systems... so, its possible its a joke. But the trucks ran great.

Ted, your right about the system not being closed, (recent thread). Me being a "pump guy' immediately associated this problem with a closed system.
However, pulsation must be there, hence the OEM damper. I've read of some guys even seeing pressure fluctuations on their pressure gauge.
Larger injectors, more flow and the stock return line diameter would add to higher back pressure.
I use the damper and this has never been an issue.
The theory still holds, if there is pressure fluctuation this type of damper could reduce it or you could even increase the return line diameter to reduce it.

There are dozens (if not hundreds) of FC owners who have done the banjo bolt replacement with no problems.
I'll let the data speak for itself.
BTW, I run the banjo bolt myself with no problems.
