Performs Better than the Ford 7.3L Blue Spring Upgrade!!
Only takes minutes to replace!! Anyone can replace it!! Save money over kits trying to sell you extra parts instead of the main product!!
This Fuel Pressure Spring works on 1994.5-1997 Ford Powerstroke 7.3L models.
The factory fuel spring can result in kinking, bending, or breaking which can cause loss of tension resulting in low fuel pressure. Low fuel pressure causes rough idles, harder starting, injector failure, and loss of fuel pressure under load which can cost you MPG and HP. The EightySixd fuel spring is shorter than the factory spring, but carries a higher preload on the plunger. The result is a spring that will not bind in your housing and will increase your fuel pressure from 35 PSI (new factory spec) to 55-60 PSI.
EVERY Ford 7.3L needs to have the stock fuel pressure spring changed out so choose the best spring which is the EightySixd Fuel Pressure Spring.
The EightySixd Fuel Pressure Spring differs from the stock spring in two ways:
- #1 is Fuel Pressure Increase: Increase your Ford Powerstroke's fuel pressure to 55-60 PSI.
- #2 is Increased Tension Lifespan: The stock spring loses about 25% of its spring tension in 10,000 cycles. The EightySixd spring loses about 1% to 3% of its spring tension in 1,000,000 cycles. Not bad for a low cost upgrade that can be installed in minutes!!
Installation Notes: Installation is simple and requires basic tools along with a T-27 torque bit. You simply remove the pump cover pieces and then remove the 2 x T-27 torque screws 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 unless you are replacing it). 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.
