JAGUAR FUEL INJECTOR SERVICE.COM

           We do fuel injector testing, cleaning, and service on Jaguar fuel injectors, and other MPI injectors.

If you own a Jaguar with the V12 5.3 liter HE engine, you are surely aware the fuel injection harness is subject to high engine heat, and yours ...if it has not been changed or repaired.... probably has hard and broken wiring insulation and may or may not be shorting or grounding out, causing non-firing ot intermittent firing of the fuel injectors.                                                                   

Fortunately, we have partnered with a manufacturer, to provide a new, aftermarket FI harness for your vehicle, constructed to exceed OEM specifications.  These are not old stock items. There are several production runs anually, so the items are new.

We currently have this new   aftermarket FI harness available to replace the OEM Jaguar V12 harness, DAC 3718.  Injector harness fits 1980 to 1989 XJS V12s, and 1990 V12 (with Marelli ignition) up to vin # 178457.

 Please note...This harness is for the 12 fuel injectors only.  Do not confuse it with the later "engine" harness for later engines, which has numerous additional plugs and wiring, and has the injection harness bundled within the "engine" harness. 

Current cost for this specific harness (DAC 3718) is..........$675.00 plus shipping to your location.  As of Feb 2025, we have one item in stock, and can ship immediately.  We can easily order more, so contact me for availability.                                 

Prior to ordering...you NEED to call 904-289-2020 or E-MAIL me your Jaguar year model, exact make, and your vehicle ID #.  We will not ship or order,  an FI harness without this information.  It avoids shipping of an incorrect harness, eliminates customer dissatisfaction, and wasted cost in shipping and time delays
