hi Ed, well, i hesitate to suggest this, based on how you got
in this predicament,(just kidding) BUT, you might try to
get a large drill bit, that will fit easily by the threads,
and, buy hand only, turn it to reface the sender seat.
please, dont be tempted to use a drill, to speed things up.
turn the large bit by hand, until the seat cleans up. then
put the sender in with some grease or something, and tighten
it a little, and take it out and see if there is contact all the
way around the seat. as far as the threads go, if they arent
completely gone, you could get a tap and clean them up.
or, worst case, you might have to drill out larger and tap
and helicoil the threads in the head.
good luck, bob smith, ohio> From: edmitche@gmail.com> To:
