Buy Ford E-350 Econoline Fuel Injectors

The Ford E-350 Econoline fuel injector-also called a fuel nozzle, spray valve, or fuel squirter-sits in the intake or cylinder head and delivers a fine mist of gasoline (or diesel on 7.3 Power Stroke models) that the engine can burn cleanly. Electronic fuel injection replaced carburetors in E-series vans decades ago and is now managed by the van's computer for better power, mileage, and emissions compliance. (Wikipedia, Bosch Global)

The Econoline nameplate covers E-350 vans, cutaways, and chassis from 1992-present. VIN code "E" identifies the E-Series in Ford's system, and the eighth VIN digit flags the specific engine-such as the 5.4 L Triton V-8 (gas) or 7.3 L Power Stroke V-8 (diesel). (Wikipedia)

• 1997-2008 5.4 L gas engines typically run yellow-body 19 lb/hr injectors rated at 39 psi. (Ford Trucks, Trackey)
• 7.3 L diesel models use electronically actuated, high-pressure oil-driven injectors that flow far more fuel under 2,000+ psi. (Accomplished Auto)

When ordering, match the engine size, model year, connector style (EV1 or EV6), and emissions certification. A mismatched injector can cause lean, rich, or no-start conditions and may damage the catalytic converter.

Each injector is an electromechanical valve. The engine control module opens it for just milliseconds, spraying a precise amount of fuel into the air stream. This replaces older mechanical systems and lets Ford meet ever-stricter smog rules. (Bosch Global, Wikipedia)
Gas engines on the E-350 use sequential multi-port injection, firing one injector per cylinder. Diesel versions use direct injection with even higher pressures and multiple injection events per stroke for quiet, clean combustion. (Accomplished Auto)

Bad or dirty injectors often show: hard starting, rough idle, misfire, poor fuel economy, tail-pipe smoke, or the smell of raw fuel. (Injector Rx)
Because unburned gas boosts hydrocarbons and carbon monoxide, a weak injector is a common reason vans fail emissions tests. (US EPA)

• Listen with a mechanic's stethoscope for a steady clicking sound.
• Use a noid light or a scan tool to confirm the injector is receiving a pulse.
• Perform a balance test-disable one injector at a time to see if engine speed drops equally.
• Check fuel pressure; low rail pressure can mimic injector issues.

Ford specifies tightening the injector hold-down clamp bolt to 38 Nm (28 lb-ft) on the 6.4/6.8-liter families; smaller gas engines use similar values. (Scribd)
Average E-series injector replacement runs about $742 - $953 parts + labor in the U.S., but cost varies by engine and region. (RepairPal.com)
Key steps:

1. Depressurize the fuel system.
2. Mark and disconnect wiring and rails.
3. Replace upper and lower O-rings; smear with clean engine oil.
4. Torque the rail and clamp bolts in sequence.
5. Prime the system, then check for leaks.

Ford's online maintenance schedule advises regular fuel-filter changes; clogged filters starve injectors. Cleaning additives can help, but badly clogged injectors usually need professional ultrasonic service. (Injector Rx)
Under dusty or severe use, replace both filters every 10,000 miles or 400 engine-hours to protect pumps and injectors. (parts.ford.com)

Stock 19 lb/hr injectors safely support roughly 300 hp at 85 % duty cycle; beyond that, larger injectors and PCM tuning are required. (Trackey) Upgrades like multi-hole Bosch EV6 injectors improve atomization and cold starts but must be flow-matched to avoid lean cylinders. (Ford Performance Parts)

A cracked injector can leak up to 19 L/hour of fuel, drip onto hot exhaust parts, and start an engine-bay fire. Ford's 2024 recall 24S16 adds leak-detection software and a drain tube. Check your VIN with NHTSA or Ford Pass to stay current on safety actions.

Efficient injectors let engines meet the U.S. Clean Air Act standards by keeping the air-fuel mix near 14.7 : 1 and reducing smog-forming gases. (US EPA) Bosch's pioneering Jetronic system proved electronic control could slash tail-pipe emissions and is the ancestor of today's Ford systems. (Bosch Global)

Q: What does a fuel injector do?
A: It meters fuel into the engine so every cylinder gets the right amount at the right time for smooth power and low emissions. (Wikipedia)

Q: How long do Econoline injectors last?
A: Many last 150,000 miles or more if the fuel and filters stay clean, but exposure to heat and deposits can shorten life. (Injector Rx)

Q: Can I drive with a leaking injector?
A: No. Leaks waste fuel, foul spark plugs, and can cause an engine fire-especially on top of a hot V-8. Have it fixed right away.

Q: Gas vs. diesel injectors-are they interchangeable?
A: No. Gas injectors run at ~40 psi, while 7.3 L diesel units need thousands of psi and a high-pressure oil circuit. (Accomplished Auto)

Q: How often should I clean injectors?
A: Use a tank additive every oil change for preventive care and have them ultrasonically cleaned if symptoms appear. (Injector Rx)

Q: What size injector supports a bolt-on cam and headers?
A: Ford's guide shows a naturally-aspirated 300 hp V-8 needs at least a 19 lb/hr injector; larger cams or forced induction may need 24-30 lb/hr. (Trackey)

Q: What torque spec should I use when reinstalling?
A: Tighten the E-series injector clamp bolt to 28 lb-ft (38 Nm) and the rail tube nuts to 12 Nm. (Scribd)

Q: How much will the repair cost?
A: Typical shop estimates range from $750 to $950 for all eight injectors on a 5.4 L van, depending on labor rates. (RepairPal.com)

Q: Does Ford cover injector failure under warranty?
A: Emission-related injectors are covered up to 8 years/80,000 miles under federal law if the part is proven defective. (US EPA)

By knowing how your Ford E-350 Econoline fuel injectors work, how to spot trouble, and how to maintain or upgrade them, you'll keep your van running strong, economical, and eco-friendly for the long haul.
