Hey guys, I have pretty easy question. I have a 99' MM700. When I bought it, I found out that the previous owner had tried to bypass the oil pump. I have the engine out and will replace the oil pump. With the engine out, I noticed that the fuel pump has a hose that was blocked off with a bolt. I know that there is Fuel in (1), Fuel out (3), Pulse (1), what is the extra hose? What does it connect to?

i know on the vipers from that era, the oil mixed in the fuel pump. so odds are the plugged line is the oil pump input on the fuel pump.
