Hello. Was told by repair person that I need a new fuel injection pump for my Branson 4710 with the A2300N2 Kukje 4 cylinder engine. Sticker Shock, more than $5000.00. I hav been looking for replacement to buy online but no luck. Anyone have any knowledge of a place to find the part. Branson parts manuel says it is HRA1300110DB1. It can be rebuilt for about $1500.00. Better, but ouch. Help me if you can.
