If you\'ve gotlow fuel pressure, this is the first and cheapest place tostart!
The Alloy of this spring is specially formulated to hold up to the extreme temperature swings of the fuel system. This means that it will withstand the 200F plus temps of hot diesel coming out of the fuel rail and be able to handle the shock of that temperature all the way down to sub zero temps and the quick swing shortly after startup for years of service. Where other springs will weaken or even become brittle and shear, these specially designed springs will maintain their integrity. These are not a cheap off the shelf spring. They are high precision polished springs. The reason for a fine finish (polished) on a spring is that any rough casting leads to early spring failure. You will find a rough finish on cheap springs. A rough finish creates the beginnings of cracks almost like perforations. Smooth finish that is found on high precision springs avoids this problem. As the end result to you, investing in quality for your vehicle pays off in reliability for years of trouble free use.
These springs are self centering (center themselves and actually fix onto the center detent of the pictured brass cap) this means that they will never get kinked in installation and will stay centered through millions of cycles. Even more importantly and by design this spring is a small amount shorter than the stock spring but with more strength. This means that there is not room for the spring to flex side to side (another cause for kinks). This means that the spring is fool proof in installation/removal and will be more resistant to radial (side to side flexing) motion which can cause the plunger to not seal properly leading to low fuel pressure.
Spring includes detailed instructions with pictures. This is a VERY easy repair! This spring is better than the stock spring because it will hold up to temperatures and cycling for years and best of all it\'s shorter but stronger and by design. The reason this helps is that it will not kink or bend which is one reason for shortened life in the original spring. It also snaps onto the center point on the FPR\'s brass cap. This is a self centering feature that ensures that the spring will end up in exactly the right position when installed. Other springs (including the OEM spring) do not have this provision that can help save your FPR and spring not to mention make it even easier to install right the first time.Some Customer Reviews (ebay feedback) on this product:Pefect fix for truck.

1. Will higher fuel pressure waste more fuel or create bad fuel economy? I don\'t want this of course...Answer:
I\'ve never heard of LESS fuel efficiency. I have experienced and heard the opposite (as you will also find in the feedback/testimonials), MORE efficiency. The reason why you wouldn\'t see more fuel sprayed with a higher supply pressure is because the fuel is precisely metered by the injectors. Only so much fluid volume will fit in the barrel/plunger assembly. Why you\'ll see more efficiency with proper fuel pressure is because if the injectors are starved of fuel they can produce air bubbles/pockets through cavitation which is not only bad for efficiency but is also harmful to the injector. With anything but fully supplied injectors you will not have an efficient spray pattern and in extreme cases, no spray pattern at all due to no fuel in the injector. This not only accelerates wear for the injector, but also hurts fuel economy because a close to perfect spray pattern is needed for ideal combustion in a diesel engine. Hope this helps and thanks for the question.
