ATTENTION: Ford has released that 6.0L Ford Powerstroke injector failure can be due to LOW fuel pressure. THIS IS THE FIX FORD HAS BEEN LOOKING FOR. SAVE ON COSTLY REPAIR BILLS, GAIN MPG AND UP TO A 20HP GAIN!! The stock fuel pressure spring runs about 50-55psi on a 6.0L and 60-80psi on a 7.3L at idle give or take some depending how long it has been run and the condition of the pump. Fuel pressure can add both power, drivability and fuel mileage. This is also a must when chips, tuners and larger injectors have been added. nstallation is simple and requires no special tools (except for a T-27 torque bit). You simply remove the pump cover pieces and then remove the T-27 torque screws (Four on the 6.0L and Two on the 7.3L) on the drivers side of the pump. Carefully separate the line from the pump and remove the spring (careful not to lose or damage the o-ring seal). Install the new spring making sure it seats properly and put it back together. It is very important to make sure the o-ring stays in its proper place. This fix will permanently optimize fuel pressure the right way and prevent the need for trying to achieve the same results by using potentially damaging and leak-causing shimming of the weak stock spring.
