Review on 🔧 HuthBrother Injector Tune Up SHIM Kit - Compatible with 1994-2003 7.3L PowerStroke Diesel Engines - No Tools Required by Jose Baldwin

The "special" tool you must have and which cannot be found anywhere other than in these kits is not included! To disassemble the upper part of the injector solenoid valve, you need a special inverted tube, which is very small and narrow. It sits between 4mm and 5mm and is much narrower than a regular socket. If you don't have this special tool you'll need to buy a kit with one of these as you won't find it anywhere except maybe a diesel mechanic's shop.
