Ok, thanks w8ye, I thought of that when I was setting up the tooling. I already did it and got it back together. If I had a small wheel it would have been better, however I did it with my boring bar with the lathe turning backwards. I turned it at about 52 threads per inch. I could have gone a little courser I guess. The process did take off a small amount of material, however it did close up the gap some and now it just barely seeps when running. Out of a half tank of fuel I only had residue that formed a drop. We will see if it gets worse with time. We will see how it runs tomorrow morning. Thanks for the tips.
