Great little diesel pump. I bought two cheaper half price pumps for the year and both failed so I went with these. Fill Rite is a big name in the fuel transfer industry so I trust their products. This pump has a built in external fuse which my other pump didn't have and that's where it blew. Burnt wires near the pump. So even if I have a power problem, the fuse should blow and save the pump. I attached it to a 30 gallon vertical steel diesel tank.
