Attention: TDR Forum Junkies 
Early 1st Gen injector pump recall number (605)
A shipment of pumps in 1991 from a supplier were developing problems by 1994 so they did a recall to replace them. If you dont have a truck maunfactured whithin this timeline then the recall does not pertain to you... ... Unless your pump was replaced under warranty before 1994 in which case they would again replace your pump because the faulty pumps were also installed during the warranty period from dealer stock. If you are a good debater and you replaced you pump in the 90's at a dealer, I don't believe they have any way to prove that you didnt get a bad pump
Pumps manufactured between March and September, 1991 (date codes 163 through 169) without an infinity symbol on the data plate or tag (rebuilt pumps). On the pumps after this, the data plates and tags have an infinity symbol on the right side. This is what the service tech is looking for. It says, "If date code is 163 through 169 and no infinity symbol is present, replace pump". This info comes from page 3 of the actual Recall service procedure
The specific pump in question was Bosch # 0 460 426 184, Cummins # 3918991.
They were replaced with Bosch 0 460 426 205, Cummins 3923346
