I see your point and concur that threaded 10-32 screws would offer better holding power and be less subject to stripping the holes (which probably happens due to over-tightening). I can still do that on 4 out of 5 holes. But I ask why tanks rarely come threaded, and why virtually all sending units are shipped with stainless deep thread sheet metal screws (sharp but not self-tapping).
The over-size hole is my immediate concern. Repair or adapt are my only options. What's the better way to resolve this? Over-drill the sender or some form of patch?
Leaning toward over-drilling the sender as Normagain opined.
Thanks.

after 20yrs in the marine biz - i've yet to see a fuel tank,the area for the sender,the holes,not to be tapped,10-32,the area is usually double thickness for the tank...
"self tapping" screws will not seal...the cheap fuel sending units-these usually come with 10-32 screws,with a sealer that squeezes out,when the screw is fully tightened...
me,personally,i wouldn't use any kind of sealing product on a fuel tank - ever !
