My 1993 B7100 Kubota is leaking at the pump. Went to bleed the system and bled it at the wrong place - at the bottom at the pump - and didn't use two wrenches. Now it's leaking at the top of the pump. Do I need to get a whole new pump or can I pull it out and put O rings and seals on it?
Don't have a part number.

You always need to bleed air from the topmost point as you already know now.

Clean around the delivery valves really good, wash it down with brake cleaner and blow it off before you start. Remove the injection one, unscrew the delivery valve, lift it out. Replace the o-ring and gasket (washer). Lube them with clean fuel and reassemble. Bleed air from the line at the injector.

O-ring = 15331-96760 One per delivery valve
Gasket = 16331-51240 One per delivery valve

Thank you very much for your help with the injector leak. My dealer only had 2 O rings in stock - luckily I only made two of them leak. I didn't know what would pop out when I took the injector out. Thanks again for the good info and part numbers. Got it sealed.
