Great idea on removing the lines at the pumps. The front pump has great supply of brake fluid to the pump but it is like syrup, and nothing comes out the top at all while cranking the engine over. I removed the carbs, I cannot get the supply line off, I need to bring a stubby wrench home. But I removed the top line, cranked the engine over and I get a little pulsing of brake fluid coming out but not a whole lot. How much should be coming out? They look like a rusty mess. The front one needs to come out for sure. Maybe the push rod is broken or the pump just corroded.
