Mechanics and DIY car enthusiasts, this 8-piece fuel injector seal kit has everything you need for a complete fuel system service! Each kit includes 8 micro filters (CF101 - 6x3x12mm), 16 injector O-rings (203 - 7.5x3.5mm), 8 injector retaining pintle caps (308 - 12x8x6.5mm), 8 injector spacers (307 - 12.6x8.4x2mm), and 8 injector seals (302 - 13x11x1.3mm). The O-rings are made from FKM VITON material that resists temperatures over 200 degrees, so they won't break down from engine heat. This universal kit replaces part number 0280150962 and works with most common injectors including 0280150943 and 0280150955. It's specifically compatible with Ford V8 5.4L and 4.6L engines too. Every component is 100% tested during manufacturing to ensure reliability and durability. When you're doing fuel injector work, having fresh seals prevents leaks and maintains proper fuel pressure. The quality is professional-grade - these aren't cheap generic parts that might fail quickly. Installation is straightforward if you're comfortable working on fuel systems. Having all the necessary seals in one kit saves you from buying individual components separately. For anyone tackling fuel injector replacement, cleaning, or maintenance, this complete seal kit ensures you have the right parts for the job. The value is excellent compared to buying OEM parts individually. When your fuel injectors are properly sealed with quality components, you get better performance, improved fuel economy, and no more fuel smells in the engine bay. This kit takes the guesswork out of fuel system repairs and gives you confidence that your work will last.
