On a 1994.5-2003 7.3L Powerstroke the exhaust back pressure tube runs from the passenger's exhaust manifold to a sensor buried behind the passenger-side fuel line and the high pressure oil pump. After twenty-some years the factory steel tube rusts, plugs with carbon, or snaps at the manifold fitting — and a tube that can't pass a clean signal gives the PCM a bad back pressure reading, which shows up as poor cold-weather starting, an EBPV that won't work properly, and a check engine light. Then you find out you have to pull the fuel line and half the HPOP to get at it.
This kit fixes both problems at once. It replaces the tube with 304 stainless bent in-house on our 3-axis bender, and relocates the sensor to a billet 6061-T6 HPOP access cover — so next time the sensor comes out with a wrench, not a teardown.
Crafted from aircraft-grade 6061-T6 billet aluminum, our HPOP bolt access cover is type II hard anodized, providing superior protection against corrosion for long-lasting performance. The innovative design includes a Viton o-ring, eliminating the need for messy RTV sealant during installation. Additionally, this kit comes complete with a new exhaust manifold adapter fitting to ensure like new functionality.
Bent on our in-house 3-axis tubing bender, and constructed from high-quality 304 stainless steel, our exhaust back pressure tube offers remarkable durability and exceptional resistance to rust—outperforming factory alternatives that are prone to corrosion and boost loss. Elevate your engine's performance while maintaining its reliability with this essential upgrade.
Bring back new life to your diesel experience today with the CNC Fabrication & Diesel Performance Exhaust Back Pressure Sensor relocation kit — where quality meets reliability!
