Need help locating the part number? The following illustrations should help. You may also wish to check our application lists for help in determining the correct part number.

Stanadyne GM DB2 Pump The part number is located on a small metal tag on the drivers side of the pump as it is installed on the engine. The part number begins with a 'DB2' and ends with the 4 digit model number. Adding these values together such as DB2-5088 will provide our part number. The 4 digit model number usually begins with a '4' or '5'. An example of a complete model number is DB2831-5088. Our GM application list is located here.	Stanadyne Ford DB2 Pump The part number is located on a small metal tag on the passenger side of the pump as it is installed on the engine. The part number begins with a 'DB2' and ends with the 4 digit model number. Adding these values together such as DB2-5069 will provide our part number. The 4 digit model number usually begins with a '4' or '5'. An example of a complete model number is DB2831-5069. Our Ford application list is located here.
Stanadyne GM DS Pump The part number is located on a small metal tag on the firewall end of the pump as it is installed on the engine. Due to the intake manifold, it is almost impossible to read any part numbers with the pump still installed on the engine. The only time the part number for this application is important is for the 1994 model year. In 1994 there were 2 different pumps, the odd one out have a model number of DS4831-5068. Our part number for this pump is S5068. For all other applications, you should be able to use our application list. Our part number is the last 4 digits of the model number with an 'S' prefix. Current available pumps include S5068, S5459 and S5521	Bosch VE Pump (VW / Cummins / Dodge) It can be very difficult to retrieve part number information from many Bosch VE pumps. It is stamped into the side of aluminum housing, near where the housing meets the head and rotor. There is normally a 10 digit Bosch part number that begins with 0 460 4 ... On later model VW engines the method used to stamp this number was lacking at best, and in many cases it simply can't be retrieved without first removing the pump from the engine.
Bosch P7100 Pump (Dodge / Cummins) Part number information for these pumps is located on a small tag attached to the side of the pump. This tag in addition to a model number and serial number, should also have a 10 digit Bosch part number. This number begins with 0 402 736 ... It should also be possible to determine the correct pump using our application list.	Bosch VP44 Pump (Cummins / Dodge) It can be very difficult to retrieve part number information from many Bosch VE pumps. It is stamped into the side of aluminum housing, near where the housing meets the head and rotor. There is normally a 10 digit Bosch part number that begins with 0 470 506 ... Part number information ma also be available from the top of the electronic module bolted to the pump. Usually this will include either a Cummins part number, or a Bosch reman number. We can normally provide the correct pump using this information. It is also possible to determine the correct pump using our application list.
Cummins PTG PTG/AFC Pump These pumps have a small metal tag located on the top of the pump right where the main housing meets the governor housing. The most common stamping number includes the CPL (Control Parts List) number, followed by the fuel code at the beginning of the first line of data on this tag. This is the information we will need to be able to provide the correct pump. Due to variations in stamping numbers this method does NOT always work. If in doubt, contact us with ALL the information from the tag.	Cummins Celect Pump The Cummins Celect pumps have a small metal tag located on the side of the pump, close to the drive end of the pump. What we are looking for is a Cummins part number. It can be difficult to determine what numbers are what, since not all tags were stamped in a consistent manner. Cummins part numbers for these pumps normally begin with a '3' or a '4' and are 7 digits long. In some cases they may have an additional 'X' or 'PX' suffix on these part numbers. If in doubt, contact us with ALL the information from the tag.
