WestGaPineStraw, Thank you for your help in looking for the Isuzu NPR's. I really appreciate it! I am looking at a truck in Tennesee. The guy said that everything is intact but the pumps are not working. He just sent me pics and I am clueless as to what I am looking at! It is obviously a pump but it appears to have a hose reel type motor on it. Any insights? I thought that these were all PTO driven?
