Greetings. Note the picture is a new Bosch fuel pump for my 76 FI beetle sedan.
Simple, and probably dumb, question: which terminal is the positive? There are NO markings on the pump of any kind to indicate.
My assumption is the smaller terminal is the positive.
Thanks in advance.

Your picture clearly shows a + sign under the left/small terminal and a - sign under the right/larger terminal.
Those markings are there to indicate +/power and -/ground. _________________ -Bruce

Godammit you are right!, disregard standard practice and go with the labels on the unit. _________________ Rust NEVER sleeps and stock never goes out of style.

Just to clarify. In case someone does not see it.

Glad you got it figured out. You don't want it reversed believe me! A friend had his reversed and spent most of a weekend pulling his hair out. The pump will run, but pump absolutely no fuel. He was slightly upset when we found the issue |
