Product Description

Lift Pump Relay Harness (LPRH) for 92-02 trucks and Suburban’s and Vans.


Buy the original. We were the first to offer LPRH. All others are a copy or version of this one.


These are a must have for every truck and Suburban.


Saves your OPS from burning out, provides proper current and voltage to the Lift Pump (LP), Takes the load off your original electrical system.


Gives you Wait To Start (WTS) Priming. This means while your glow plugs are activated the LP is also on. This primes the fuel system before you actually crank the engine.


Has an on/off button next to relay so you can turn LP on anytime from under the hood, this is a great feature when you replace the filter element and need to bleed the air out.


LP will pump better, live longer and do a better job. The Injection Pump (IP) needs proper volume and psi also if you starve the IP it has to work harder and dies an early death. Fuel cools and lubricates the IP.


Again this is a must do modification.

Old video below but you’ll see how to install your new LPRH. (we do not sell Walbro or Carter pumps since they moved to China for manufacture, the quality is really bad now)
