Brad Smith (verified owner) –
Injection pump as described. Arrived well packaged via USPS. Also contained necessary umbrella seals and steel washers for banjo bolts on each injector line. Pump was painted primer gray. Plugs sealed all openings. Staff at Oregon Fuel Injection promptly and courteously responded to email, phone, and web form questions. Excellent customer service. Core charge refund issued the day after the old pump arrived at OFI. OFI also has helpful written installation instructions for this class of pump (Roosa Master/Stanadyne JDB). Tractor working well with replacement injection pump. Highly recommended.
