Free Shipping
Please Call for Availability


The DT73AE injector is referred to as a long lead injector and is only used in the number eight cylinder on the applications as noted below.

In the 1999 model year there were two different variations of the 7.3L engine used. Each variation requires different injectors.

1999 model year engines with serial number 896811 or below use the DT73AB injector. The DT73AE injector is not to be used with the DT73AB or incorrect engine operation and DTC will result.

1999 model year engines with a serial number of 896812 or above use the DT73AD injector. It is optional to use the DT73AE injector in cylinder number eight to reduce an engine cackle noise.

When the DT73AE is used on engines with a serial number below 1311240 the PCM must be reprogrammed to the latest calibration to prevent a false contribution test DTC. Customers can refer to Ford TSB 03-21-39 for more information.

The serial number tag is located on the oil reservoir for early engines and the valve cover for late engines. On all engines the serial number is stamped into the block at the rear oil cooler pad located at the lower left side of the engine block reward of the oil filter.
