Cummins 3.9L & 5.9L& 8.3L 4937766 3968190 3968188 Fuel Transfer Pump 5260632

Got this high-pressure fuel pump for my Nissan Juke. Fits perfectly and installed without trouble. Now the engine runs way smoother, with better acceleration. Solid build, works as expected. Great replacement—saved me from a pricey shop fix. Happy with it!

Dose what it should just put it in two days ago

Included detailed guide and seal kits. DIY installation took one hour. Pressure tests show perfect spec compliance.

A genuine feeling product. It has the correct weight and all the fittings are precise. My truck's fuel system is protected.

Ordered this valve on a Tuesday and it was at my door Thursday. That is fantastic speed for a small part. The envelope was sealed well and the part was protected in a small box inside.
