We are all here to help! If it looks like he can get some bite, then go for it, but IIRC the opening on that bottom portion isn't very big. Even so, maybe you could get a small EZ-out in it.I wouldn't presume to argue with Bismic but you may not need to pull the valve cover. If you have a square easy out that just barely fits in what's left of that sender it should come out easily. Its an ORB fitting so its not really all that tight.
