I've bought two in the last year. First one is a chinese made stainless steel unit that had a too long pickup and sender that ohmed out of the acceptable 73-10 range. I replaced it with a Mexico made Spectra Premium unit that had a shorter pickup tube and is spot on at 73-10.
Problem is OEM units measured on a curve. 73 ohms empty, 24 ohms half, and 10 ohms full.
The Spectra Premium measures linear. 73 ohms empty, 45 ohms half, and 10 ohms full. Luckily I have a digital gauge and can set it up to read properly.
To have a sender that works with stock gauge you'll need NOS.
