What We Service

Tank to Injector. The Whole Fuel Path.

Modern diesel fuel systems fail in four places. We service all of them, because replacing injectors without fixing the pump that killed them is how the new set dies early too.

01

Injectors

Fuel injector diagnostics with cylinder balance and contribution testing before condemnation. Single injector replacement or full sets, installed to spec with new seals and cups where required, then coded to the ECM. Injector cleaning service is available where cleaning is the appropriate fix rather than replacement.

Tested First ECM Coded

02

High-Pressure Pumps

CP3, CP4, and HPFP diesel fuel injection pump repair and replacement. Rail pressure tested under load, not just at idle. A failing CP4 gets caught before it grenades and sends metal through the whole system.

Rail Pressure Under Load

03

Supply, Lift Pumps and Filters

Lift pumps, diesel fuel filters, fuel water separators, lines, and pickup screens. Supply pressure verified to spec, because a starving high-pressure pump fails early and takes the injectors with it.

Supply Verified Filters and Lines

04

Contamination Cleanup

Bad fuel, water intrusion, or pump failure debris. Tank dropped and cleaned, lines flushed, diesel water separator inspected and replaced where needed, every downstream component verified, and the system documented for insurance or fuel-supplier claims.

How It Works

Test. Replace. Verify.

Injectors are too expensive to guess at. Every diesel fuel system repair here runs the same three steps, in order, no skipping.

01

Fuel System Diagnostics

Cylinder contribution, balance rates, rail pressure under load, and supply pressure. We identify which injectors actually failed and what upstream cause killed them before a single part is quoted.
02

Replace to Spec

OEM injectors and pumps through our Bosch dealer line. New seals, cups, and hardware where the platform requires them. Installed to manufacturer torque and coded to the ECM.
03

Verify Under Load

Balance rates rechecked, rail pressure confirmed under load, and a road test before delivery. The same tests that found the problem prove that it is gone.

Standards & Capability

Precision Work. Or It Comes Back.

Diesel fuel systems run at pressures north of 25,000 psi. At that level, attention to detail is not a slogan. It is the difference between a repair that lasts and one that takes the engine with it.

Official Bosch Dealer OEM injectors and pumps through an authorized line. No gray-market or remanufactured mystery units in a system this unforgiving.
Root Cause Found Clogged or dirty fuel injectors usually have an upstream cause: supply starvation, contamination, or a failing pump. We find it so the new parts survive.
Clean Room Discipline Fuel system work is done with capped lines, cleaned fittings, and zero debris tolerance. One grain of grit at 25,000 psi destroys a new injector.
Test-Driven by Chris Every fuel system repair is verified under load and personally test-driven before release. Zero comebacks in 2025.

Injector and Fuel FAQ

Common Questions

What are the signs of bad diesel fuel injectors?

Common symptoms of bad fuel injectors include rough idle, white or black smoke, hard starts, fuel knock, fuel in the oil, and a dead miss on one cylinder. None of those alone condemns an injector, which is why we run cylinder contribution and balance testing first. You only pay for injectors that actually failed.

Do I have to replace all my injectors at once?

Not always. On a lower-mileage engine with one verified failure, a single replacement makes sense. On a high-mileage set where one failed from wear, the rest are usually close behind and a full set saves repeat labor. We give you both numbers and the honest reasoning, then you decide.

Do you use OEM injectors?

Yes. We are an official Bosch dealer and install OEM injectors and pumps where they exist, with the best available standard when OEM is not made for the platform. Cheap remanufactured injectors are the most common cause of repeat diesel fuel system failures we see, and we will not install them.

I got bad fuel. Can the system be saved?

Often yes, if it is handled completely. We drop and clean the tank, flush the lines, replace filters and the diesel fuel water separator where needed, and inspect every downstream component including the pump and injectors. The damage is documented with photos for an insurance or fuel-supplier claim. A partial cleanup is how contamination comes back.

What does diesel injector replacement cost in Midland, TX?

Diesel injector replacement cost depends on the platform, how many injectors actually failed, and whether an upstream cause needs fixing. Every job is quoted custom after fuel system diagnostics, itemized in writing before work begins. Call (432) 557-6500 and we will tell you what the testing involves for your truck.

Do you service diesel fuel systems across the Permian Basin?

Yes. We serve Midland, Odessa, and the wider West Texas and Permian Basin region. For a full overview of our diesel services, see our diesel truck repair and engine rebuilds page. If the fuel system issue points to deeper engine damage, our diesel engine repair team handles that in the same shop.

Miss? Smoke? Fuel Knock?

Get the system tested before you buy injectors it might not need. Verified diagnosis, OEM parts, and the upstream cause fixed so it does not happen twice.
