Re-read YOUR post #2 above. It says "thanks for the overwhelming flood of assistance on the call for help!!
Saved me oodles of research & phone call time"
If you were trying to be sarcastic, know that sarcasm doesn't work very well on internet forums.
As for the linear gas sender I have now, I may not care for how it is calibrated, but my factory gas gauge does not act crazy, it just shows "empty" when I still have 1/3 tank left. Beats the heck out of having no working gauge at all!
My Spectra brand sender was labeled "made in Canada".
