take it off and get it rebuilt at a pump shop. will be cheaper than buying a pump outright.

Check with Injector Ed on the site, I'm sure he can rebuild yours for less then a new one or even a used one that you don't know the history of.

Thank you for the information. Is there a website to look that up ? How do you break down the serial number.

I have not come across any website that posts the serial #'s to the year of the Allis Industrial line of machines. I have a serial # book by 'Primedia information inc.' that is more than 20 years old now. It includes a lot of the old Allis equipment but I have no info on newer equipment. The first 545 to be built in 1969 was #2795 and the last in that year was #3317.

Unless your pump is seized, it should be pretty reasonable to just rebuild yours. It'll be similar to other pumps for AC 301 engines.
