snobli Truck Fuel Cap 2.25" Aluminum — 11.5 TPI NPSH Female Thread, Non-Vented with Stainless Chain

snobli's non-locking, non-vented 2 1/4" die-cast aluminum fuel cap fits Ford 650/750 tanks, Reefer and International MD box trucks with an 11.5 TPI NPSH female thread.

This replacement fuel cap is built specifically for diesel box trucks and reefers requiring a durable, non-vented closure. It uses a female fitting with 11.5 threads-per-inch NPSH, measures 2 1/4" across, and is cast from aluminum for corrosion resistance. The cap is supplied with an 8" stainless chain and a 6.5" stainless retainer wire to keep the cap attached when refueling. Always confirm your tank's cap diameter and thread type before ordering.

How will this snobli cap fit my Ford 650/750 or International MD truck?

This cap is made for tanks with a 2 1/4" diameter opening and a female 11.5 TPI NPSH thread. It is a non-vented, non-locking design intended for diesel tanks only, so compatibility depends on those dimensions rather than truck model names alone.

• 2 1/4" outer diameter suited to common Ford/International tank ports
• Female fitting with 11.5 TPI NPSH thread—matches NPSH male tank necks
• Non-vented design for systems that require sealed caps
• Diesel-only specification—do not use with gasoline

What materials and parts are included, and why do they matter?

The cap body is die-cast aluminum for strength and corrosion resistance in road and marine environments. Stainless attachments reduce rust and keep the cap secured during service stops and vibrations.

• Die-cast aluminum cap body for durability and lighter weight
• Non-vented interior to maintain sealed fuel systems where required
• 8" stainless chain to prevent dropping the cap during refuel
• 6.5" stainless retainer wire for a secure tank attachment point

How do I check if this cap is the right replacement for my tank?

Measure your tank opening and inspect the thread type before purchase. The critical values are a 2 1/4" cap diameter and 11.5 TPI NPSH female threading; if those match your tank neck, this cap will fit and function properly.

• Measure the tank opening diameter across the sealing surface: should be 2 1/4"
• Verify thread: male NPSH on tank neck with 11.5 threads per inch
• Confirm fuel type: designed for diesel tanks only
• Non-vented cap suitable for sealed fuel systems—ensure system needs non-venting

Will the non-vented, non-locking design affect everyday use?

A non-vented cap creates a sealed closure that some fuel systems require to control vapor and pressure. Because it is non-locking, it is simple and quick to operate at service stops but does not provide theft protection.

• Non-vented: maintains closed fuel systems and reduces vapor loss
• Non-locking: fast access when refueling but no keyed security
• Included chain and retainer reduce risk of losing the cap during refueling
• Recommended for diesel-only tanks to avoid cross-contamination issues

Who is this for: Fleet managers, owner-operators, and maintenance techs who need a rugged, simple replacement fuel cap for Ford 650/750 tanks, reefers, and International MD box trucks with a 2 1/4" opening and 11.5 TPI NPSH threading. Choose this snobli cap when you want a corrosion-resistant die-cast aluminum closure with stainless hardware for reliable on-the-road service; just confirm thread and diameter before purchasing.
