The reason for the VP44 issues is NISSAN. The pump is designed to have a lift-pump feeding them, supposed to have around 1 BAR (14.7PSI). Nissan went cheap and expects the VP44 to draw fuel through restrive lines and filter before it has to push it up to around 200-250PSI to control the pump timing rack piston and prime the injection plungers. Issue made worse with all the bolt-on filter kits that flood the markets making things worse. Fit a Carter Black pump in rear near the tank, modify the fuel return to feed the pump bypass and injector return back to the tank (stop the hot fuel and in some cases carrying air back into the pump supply) and you will see the VP44 sing and last forever.

My injector pump on my GU Patrol was done a couple of years ago at a cost of $2500, fingers crossed it lasts for many more...

Would be great to see a video on this process. Looks a huge job.

Hi Phil.. I’m working on 2011 D22 Navara .. it’s start and runs ok but the issue is 5 seconds after start it’s cuts off if I don’t hold the acceleration.. the only thing I found is fuel run back in the tank and filter primer pump struggle to prim back..

replace the fuel filter with a genuine one and if there is a black T on the top replace that as well

@@PTPrecisionAutomotive first of all thanks 🙏 a million for the reply, I will change the fuel filter and see how it’s go.. just to let you know that this is spin on fuel filter not the Z711 one so the primer is on top of the fuel filter no black T!

Good way to overcomplicate things. Takes 2 seconds. To get that pump out once the chains off.

Have a similiar issue with a 2007 Y61,how much approx did that job cost?
