Another Electric Fuel pump wiring question.

I disagree using a breaker instead of a fuse. Automotive breakers have a poor track history of protecting circuits. Even the Dodge trucks use a fuse supplying the pump. Find out what your pump draws, and fuse accordingly. Make sure the 10Ga is actually enough, and don't use "household AC" amp capacity wiring charts, use a chart for 12V. They are all over the internet

This is because, "generally" automotive cannot stand the same voltage drop as house circuits. A good example is something electornic/ sensitive, like a radio/ stereo or eFI computer
