I have a fuel pump motor that is submerged in the fuel tank (gasoline). I'm having an issue with the brush life when the speed and flow rate is increased (increased current). I have researched the issue in the Engineering Tips forums as well as internet search and I've found some (very little) information. Does anyone have experience with this type of application? I could use some help when I begin to analyze the problem. I can't find any information with respect to acceptable current densities for this application as well as acceptable speeds and spring forces for the combination of carbon commutator with carbon brushes submerged in fuel. Thanks in advance for your help.
