Lift Pumps & Supply
Lift pump, transfer pump, and priming issues. Fixing air in fuel, low supply pressure, and hard-start conditions.
Filtration
Fuel filter replacement, water separator service, and addressing restricted flow that starves the high-pressure side.

Why Fuel System Work Belongs in the Shop
Precision & Safety
High-pressure diesel fuel systems require correct tooling and procedures. We work safely and to manufacturer expectations.
Right Parts
OEM and quality aftermarket components matched to your application - so repairs last and warranties stay intact where applicable.
Avoid Repeat Failures
Contamination and air leaks ruin new parts fast. We identify root causes - bad fuel, failed filtration, or leaks - before we button it up.
North Idaho Diesel Experts
Serving Bonners Ferry and the surrounding area with the same care we bring to every diesel that rolls through our bays.
Symptoms We Diagnose
Fuel system problems often show up as driveability issues. If you notice any of these, have it checked before minor wear becomes major damage.
Hard Starting / Long Crank
Weak supply pressure, air in the system, or high-pressure pump issues can make cold starts and hot restarts difficult.
Loss of Power Under Load
Restricted filters, failing lift pump, or inadequate rail pressure can leave your truck short on power when you need it most.
Rough Idle & Misfires
Injector balance, spray pattern, and electrical issues can cause uneven running and codes related to cylinders or fuel delivery.
Poor Fuel Economy
Leaking injectors, incorrect rail pressure, or dragging pumps can burn extra fuel without obvious warning lights.
Fuel in Oil / Dilution Concerns
Some injector failures allow fuel into the crankcase. We diagnose the source and recommend the right repair path.
Water or Bad Fuel
Contaminated fuel damages pumps and injectors. We help identify contamination, service filters, and get the system clean again.
