SasquatchParts In-Tank Lift-Pump Adapter Harness for Jeep Liberty 2.8L CRD

This upgrade is among the most important for the Liberty CRD. This vehicle should have had the fuel lift pump right from the factory, but it appears that the bean-counters nixed this idea to keep costs down. This is the main reason why CRD engines have fuel issues. With a lift pump installed you will experience better starting, especially in cold weather. You may also notice quicker throttle response and the engine runs and idles smoother. You can be sure you never have any fuel aeration issues and never need to hand pump the fuel filter head again.

Air-in-fuel problems inevitably arise on the Liberty CRD platform due to a fundamental design choice to not implement a low-pressure in-tank lift pump like what was standard equipment on the Dodge Cummins which shares a similar high-pressure CP3 fuel pump with the Liberty CRD. Jeep did give us a relay and a fuse, but the in-tank lift pump was scrapped for production: clearly a cost-savings measure, rather than a technical one.

Installing a lift pump eliminates air-in-fuel issues, reduces load and wear on the high pressure CP3 pump, and improves cold weather starting. Our plug-and-play harnesses make the Cummins low pressure, in-tank lift pump retrofit process as easy as possible, saving time and reducing hassle. Our top notch wiring harnesses are made by hand in small batches in the USA. We only use brand new OE-quality wiring and sealed connectors; everything is professionally soldered, shrink-wrapped and loomed.

You will also need a Cummins P76148M In-Tank Lift Pump.
