Fast Fueling Pressurized Fuel Tank Vents: V150, V150A, V150B, V150F & High-Volume V150H / FVH

In pressurized fast-fueling systems, the fuel tank vent mounts at the top of the tank to perform two critical tasks: exhausting displaced air during high-speed fuel delivery up to 150 GPM and sealing the vent port via an internal float once fuel reaches the full level.

This controlled pressure rise (reaching the 12 PSIG threshold) triggers the automatic shut-off piston inside the N150 nozzle. The lineup includes V150, V150A, V150B, V150F, and the High Volume Fuel Vent V150H / FVH featuring a standard 5-inch (127 mm) stem.

Fast Fueling Pressureless Refueling Systems: Standard Kit & Caterpillar D7–D11 Dozer Kit

Pressureless fast-fueling systems eliminate internal tank over-pressurization during automatic shut-off, protecting thin-walled or complex-shaped diesel tanks from bulging and weld fatigue.

When fuel reaches the full mark, the top-mounted pressureless vent level controller sends a hydraulic pilot signal directly to the tank shut-off valve, stopping flow and triggering the nozzle without pressurizing the vessel.

Fast Fueling supplies the universal Pressureless System Kit Standard alongside dedicated kits for Caterpillar D7–D11 bulldozers.

Pressureless System Kit Standard: compatible with 95% of heavy equipment fuel tanks across Caterpillar, Komatsu, Volvo CE, John Deere, Hitachi, and Liebherr
Installs via two 2" NPT tank ports (one top port for the vent controller, one lower port for the receiver) with port spacing up to 8 ft (2.44 m)
Dedicated D7–D11 Cat Dozer Pressureless Kit featuring a 6-bolt CAT vent flange and remote ground-level fueling receiver configuration
Zero tank pressurization during shut-off, preventing structural tank damage and fuel spills

For multi-fluid service banks on haul trucks and excavators requiring multiple viscosity grades of gear, axle, and hydraulic oils, Fast Fueling produces selective 3/4" NPT color-coded couplers in the Flat Face and Matrix series.

Flat Face couplers (FFN female nozzles and FFR male receivers) feature a flush, wipe-clean mating face that minimizes dirt inclusion and mechanically keys each color code so a nozzle can only couple with its exact color-matched receiver.

The Matrix Series (N307–N380 and R307–R380) provides 8 distinct keyed fluid channels.

Flat Face Female Nozzles 3/4" FNPT: FFN210, FFN230, FFN240, FFN250, FFN255, FFN260, FFN265, FFN270, FFN275, FFN280, and FFN285

Identifying Fast Fueling (Fast Fill Systems) Assemblies by Part Numbers and Cross-References

For over 30 years, Fast Fueling Systems / Fast Fill Systems (an operating division of Nozzle Tech, USA LLC, Utah, USA) has engineered and manufactured closed high-flow diesel fueling systems and service fluid quick couplers for mining haul trucks, excavators, bulldozers, wheel loaders, fuel lube

trucks, and locomotives.

To select the exact nozzle, onboard receiver, or seal kit, provide the factory part number stamped on the body or listed in your parts manual: fuel nozzles N150PSLp (N150SL), N150PBp (N150PB), N150Tp (N150T), N150Cp (N150C), and N800AT; receivers R150CVc, R150Sc, and R150Sc-j; fuel tank vents V150,

V150A, V150B, V150F, and V150H (FVH); hose swivels S150 and S200.

Fast Fueling 1-1/2" and 2" NPT assemblies are dimensionally and functionally interchangeable with industry-standard Wiggins fast-fill systems (ZZ9A1, ZZ9A2, ZN2A, ZV150), allowing direct replacement of worn nozzles, receivers, and seal kits without modifying vehicle piping.

Selecting the Right Diesel Fuel Nozzle: Piston Sureloc, Pitboss, Titan, or N800AT

When outfitting mobile fuel/lube service trucks and stationary mining fuel islands, nozzle selection depends on environmental contamination levels and target flow rate. The N150 series nozzles feature a 1-1/2" FNPT female inlet thread and are rated for up to 150 GPM (568 LPM).

The Piston Sureloc (N150PSLp / N150SL) incorporates 12 stainless steel ball bearings and a thick-walled all-metal housing built to withstand severe impact loads.

The Pitboss (N150PBp / N150PB) utilizes the proprietary Elastodog latching mechanism, preventing latch jamming caused by mud, coal dust, sand, and ice.

The lightweight Titan (N150Tp / N150T) pairs the Elastodog latch with a field-replaceable piston cartridge that can be serviced in 10–15 minutes. For ultra-class haul trucks and rail locomotives, the high-flow N800AT nozzle delivers up to 211 GPM (800 LPM).

Upgrading Fuel Tanks with R150CVc Check Valve Receivers

Onboard fuel receivers mount into the bottom or side wall of the fuel tank via a 2" NPT male thread. The standard steel receiver R150Sc (and extended-stem variant R150Sc-j) features a green indicator poppet and is calibrated for a 12 PSIG (0.83 bar) automatic nozzle shut-off pressure.

The patented R150CVc (Fuel Check Valve Receiver) integrates an internal check valve directly into the mounting body.

When a receiver stem requires scheduled maintenance or replacement due to impact damage, the internal check valve blocks diesel fuel from flowing out, enabling replacement without draining hundreds of liters of fuel from the tank.

In addition, the R150CVc check valve architecture prevents unauthorized fuel siphoning and theft through the fast-fill receiver port on heavy construction and mining equipment.

Pressurized vs. Pressureless Fast Fueling: V150/FVH Vents and Pressureless Kits

Conventional pressurized fast fueling relies on a sealed fuel tank paired with a float-operated fuel tank vent (V150, V150A, V150B, V150F, or high-volume V150H / FVH with a 5" / 127 mm float stem).

During fueling, displaced air exhausts freely through the vent; once fuel reaches the full level, the float rises, closes the vent path, and builds up to 12 PSIG (0.83 bar) of backpressure to trigger instant nozzle shut-off.

For machines with thin-walled or aluminum tanks not rated for internal pressurization, the Fast Fueling Pressureless System Kit provides closed high-flow fueling without tank pressure. The Standard kit fits 95% of fuel tanks and installs through two 2" NPT ports spaced up to 8 ft (2.44 m) apart.

For Caterpillar D7, D8, D9, D10, and D11 track-type tractors, a dedicated Pressureless System Kit includes a 6-bolt CAT vent flange adapter and braided signal line.

Service Fluid Couplers R100–R400, Flat Face, and Matrix Selective Couplers

For centralized ground-level service banks on heavy machinery, Fast Fueling manufactures threaded evacuation and refill couplers rated for 500 PSI (34.5 bar) maximum operating pressure and 1500 PSI (103.5 bar) minimum burst pressure.

Distinct thread sizes and coupling profiles prevent cross-contamination of fluids during preventive maintenance.

The standard product line covers four dedicated circuits: crankcase engine oil (3/4" NPT: receivers R100c, R100Rc, nozzles N100p, N100Up), radiator coolant (1/2" NPT: receivers R200c, R200Rc, nozzles N200p, N200Up), hydraulic oil (3/4" NPT: receivers R300c, R300Rc, nozzles N300p, N300Rp), and

transmission oil (1/2" NPT: receivers R400c, R400Rc, nozzles N400p, N400Rp).

For multi-grade lube trucks requiring strict segregation of oil viscosities, Fast Fueling offers color-coded Flat Face Series couplers (FFN210–FFN285 and FFR210–FFR285) and mechanically keyed Matrix Series selective couplers (N307–N380 and R307–R380 with 8 independent keyed positions).

Field Maintenance, S150/S200 Hose Swivels, and Fast Fueling / Wiggins Rebuild Kits

To eliminate hose kinking and torsional stress on fuel reels and dispensing islands, heavy-duty ball-bearing hose swivels S150 (1-1/2" NPT) and S200 (2" NPT) are machined from cold-rolled steel with full-bore internal passages.

When shut-off response slows or minor weeping occurs, nozzles and receivers do not require complete unit replacement: the modular Fast Fueling design allows field technicians to replace the piston cartridge, springs, latches, and fluorocarbon seals on site.

We supply genuine factory rebuild kits for both current Fast Fueling models (N150PSLp, N150PBp, N150Tp, R150CVc, V150) and installed Wiggins assemblies (series ZZ9A2, KR93, JNX, and ZN2CV), along with anodized aluminum and composite dust caps RP150 and vinyl nozzle plugs NP150.
