Have a 1968 ford 3000 with a Simms pump. I was going to
change the oil in pump and pulled what I believed to be the
full level plug, out came loads of diesel fuel. I was going by a
diagram I seen on the Internet. So how is it getting fuel in the
oil? Bad diaphragm in the fuel pump is my guess. But I wanna
make sure the plug I pulled is what I think it is. It?s to the front
of pump just a little over a arm that looks like it would be to
adjust the govnor.
