Quality gas tank sending units?
Need advice here. In the last year, both gas tank sending units in the '70 & '73 TA's died. Lucked out & got a NOS unit for the '70, but had to settle for a repro bought through Bob's Chevrolet Parts for the '73. But I have similar problems with both. They stay on full or near full for way too long and then I've actually run out of gas with them still reading above 1/4 full. I can drive almost 150 miles before the needle starts to drop.
I've cleaned the grounds more than once, no improvement. I can remove the senders from the tanks, hook them up as normal, and test them on the cars moving the float arms through the full range and they read properly. What gives?
