Well for those of you who caught my last post you know that the fuel pump went out in my 98 cobra. All in all I replaced it with a Walbro 255 pump. I trimmed up the cap to get it to fit nicely. Sealed up the tank and the car fired up great. Seemed like everything was good to go. That is until I got it out on the freeway this morning for a "real" test drive. Unlike the trip around the block that I did yesterday after I got it all buttoned up. I hit the gas and around 3000 rpm loose all power. I figure that is weird, but I did just disconnect the battery for a few hours maybe the 02 sensors have not come back up yet. About 50 babied miles later the check engine light comes on. The codes read lean condition bank 1 and bank 2. Now I am remembering that the Walbro 255 is a bottom feed pump compared to the stock side feed. I am wondering if the pump is pushed too hard against the bottom of the basket and restricting the flow. Does this sound feasible. I was thinking about drilling a good size hole in the bottom of the basket right below the pump intake to allow it to "breathe". Any other ideas? Thanks!
