It states on the first page of the Industrial Inj. website New computer on all Bosch VP44 pumps. that and the price is the reason for choosing them, that and being a certified bosch rebuilder.I found that most secondary outlets that handle these pumps add at least 1000.00 to the price and both are charging for the core.For example Autozone,advance sell Cardone brand 2300.00 looked up on webb from Cardone the same pump is 1150.00 400.00 core charge the core charge at Autozone and Advance is 500.00. I wouldnt consider buying one of these pumps was just checking. As everyone already knows its all about Money,What can I not do and make the most $$$$$
