I just got a new sending unit/pickup for a new replacement tank. It is for a carbed car. As I see it, both are correct. However, when I went to install the sending unit in the tank, the pickup bottomed-out on the tank before the tophat sat flush to the top of the tank. The top hat ever-so-slightly sat an angle (1/16") and I could feel the tension with the pickup buried to the floor of the tank. The easy fix for me was to slightly bend the tube upward and I did it a little at a time to unsure it was as close to the bottom of the tank as as possible. I finished with the top hat settling nice and level on its own (no great pressure) but a hair (1/16"- Guessing!) of wiggle at the pickup end.
My question is, is there suppose to be zero clearance at the pickup end or a certain gap? I could not find any install information in my Hayes manual and nothing brought up here. I was wondering if anyone recalls how it was when they did theres.
