Thumbs up M3 fuel baffle installed successfully!

Allright guys,

Today I was able to install the E46 M3 fuel baffle in my ZHP, thanks to all the good info on this site. Thanks Mr. Paddle Shift and Ben Liaw, your instructions and pictures were great...

I think the most difficult part was to remove the metal ring that holds the fuel pump ensemble sealed in. All you need to do this is 1. a large flathead screwdriver, 2. a hammer and 3. balls so you can confidently whack the thing knowing there's fuel underneath. Oh and be prepared to replace the fuel hose metal clamp, I destroyed the OEM piece while removing it. I also placed some leftover paint over the clamp screw to hold it tight, because I couldn't find my loctite tube (the paint was VW Tornado Red to keep with the red theme of my car, in case someone's interested).

I took the car for a quick spin and everything seems to be working seamlessly. Of course despite my best efforts I wasn't able to generate too many G's in the neighborhood, so a full report will have to wait until my first track outing. I have to confess I'm still a little baffled ( ) as to how exactly it works, but I don't think you can go wrong for $16...

If you track your car or auto-x, I think it's prudent to do it. Having erratic throttle behavior in the middle of a fast corner can certainly mess with your concentration. If your car hasn't experienced the fuel starvation yet, try harder.

Once again, thanks for the info!
