Have any of you installed a Walbro 255 HP fuel pump in your EF's? I just did yesterday and now today it is noisy as heck. Sounds ruff too…. So just wondering if I need to drop the tank again and look things over or if this is a common thing with a pump this size. I can even hear it at idle. My fuel PSI is at 42, any help would be great because this noise is driving me nuts!

Oh I am running a fairly stock B16A (minior bolt on's) in case that matters. Also notice that my car started missing and chuggning from a dead stop the last few blocks today.
