X1 Connector Pin Failure

With 200 hours on my aircraft, my main fuel pump was running a bit slower and less confident sounding than the aux pump. I traced the problem back to a high resistance connection on Socket 11 of the X-1 (Lane A) connector on the bottom of the fuse box assembley. The socket in the #11 position feeds the main pump and it was discolored and oxidized like it had been warm. I believe the heat broke down the spring tension in the femal socket causing a poor connection. Given the fuel pumps are fairly high current and a run continually, this looks like a probable failure point. I was wondering if anyone else had seen this problem?
