I have a late 31 Cpe in which I have installed a model B engine & I am using a model B water pump with a new model A radiator & the pump pushes to much water, causing it to be pushed out the over flow tube . Should I cut some steel off the pump vanes , or try to narrow the opening out of ther top of the pump. Has any one has sucess using a B pump in an A radiator . Please advise Thanks
