My FMU pulsates like it has air in it? Esp when I;m at idle I can hear little spurts and feel it when I hold the FMU..anyone else have this problem? I'm thinking of switching to a smaller fuel line so I won't hafta clamp the line so much. I don't see any kinks or leaks at this time. Any help is appreciated.

It's not injector pulse that would be way too fast. It feels like something is kinked or like air is in the system.

Mine makes a funky noise while the car is idling also. It has done it since the kit was first put on.....no big deal.

I did not grab mine though, I am going off of the chhhhh chhhhh chhhh sound when the car idles.

If fuel pressure builds in boost and you get the proper egt when you boost, then I would not worry about it.

I checked to see what line it was comming from and the pulsing and spurting is comming from the top line off the FMU. I think that goes to the fuel rail. I'm gonna try to take off the FMU and run it w/o it. Will it run stock FP even if I have a Hi-flo pump? What is the path of fuel from pump to injectors? thanks
