My name is David I'm just starting with me and my brother a power washing business. Just recently we bought a used power washer its a 13 horsepower Honda motor but I'm having issues with the pump its a General Pump 4GPM . the question that I have is instead of buying a new 4GPM Pump can I upgrade it to 5.5 GPM pump right now I have installed a T9281 pump and I want to install a TS2013 pump. The spec are the same or very close
