Upgrade Your High-Pressure Oil Pump (HPOP) Lines with Our Kit!

Eliminate the typical costly, high-mileage, and leaky OEM HPOP lines and STC Fittings with our kit. It includes all the necessary fittings for the passenger side, driver side, and crossover hoses to get rid of the quick connect fittings on the heads and HPOP itself.


The crossover line is responsible for balancing the high-pressure oil system in each head, resulting in better engine idle and possibly reduced noise.


However, when installing these lines, make sure to disconnect your batteries first. Inadvertently shorting them to the glow plug relay, IAH Relay, or alternator may cause them to arc, quickly melting or causing more serious damage.
