FAW J6P Fuel Tank: Desconstruindo 22 Critical Parts for Flawless Fuel Delivery

Welcome to this expert deconstruction of the FAW J6P Fuel Tank (Main Assy P/N 1101010-14BJ). Este é o completo “fuel storage and delivery” sistema para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando.

This is not just a metal box; it is a complex 22-component “Logic Assembly” engineered to store fuel, manage “slosh,” prevent leaks, and deliver a constant, air-free supply of diesel to the engine’s high-pressure system.

O “Anti-Surge Logic” is the most critical internal feature of this FAW J6P Fuel Tank. A heavy-duty dump truck operates on extreme inclines, declines, and severe side-tilts. Esse “sloshing” of fuel is a major problem. If the fuel pickup tube becomes uncovered for even a split second, it will suck air. Air in a high-pressure common rail (HPCR) system can cause stumbling, power loss, and can permanently damage the injectors. O “lógica” disso FAW J6P Fuel Tank is that it contains internal “baffles” (walls with small openings) that “corral” the fuel and trap it at the pickup point, guaranteeing a solid, air-free supply of fuel regardless of the truck’s angle.

This technical guide is an essential resource for chassis technicians, fleet maintenance managers, e especialistas em peças. We will deconstruct the entire 22-component group. Iremos analisar o “Reservoir & Venting Logic” (the main FAW J6P Fuel Tank and cap), o “Structural Mounting Logic” (the anti-vibration brackets), o “Critical Clamping Logic” (the straps and gaskets), e o “Plumbing & Flow Logic” (the main inlet and return pipes) that connect the FAW J6P Fuel Tank to the engine’s fuel filters.

Essencial 1: O “Reservoir & Venting” Lógica (Componentes 1, 2, 3)

This group forms the main “armazenar” componente do FAW J6P Fuel Tank sistema. Its logic is to hold the fuel, manage internal pressure, and prevent sloshing.

1. Componente: ‘Fuel tank assy’ (1101010-14BJ)
Esse (Comp. 1) é o principal FAW J6P Fuel Tank. Isso é “Material Logic” is either high-strength, corrosion-resistant steel or lightweight aluminum (to save weight and increase payload). Isso é “Reservoir Logic” is its large, 400L+ capacity, designed for long-haul operation. O mais importante “lógica,” however, é interno:

2. O “Anti-Surge Logic” (Internal to Comp 1):
Inside the FAW J6P Fuel Tank são “baffles.” These are internal walls with small, strategically placed holes. Deles “lógica” is to act as “dampers” for the fuel. When the truck brakes hard, the entire 400L mass of diesel “sloshes” forward. These baffles prevent that “surge,” which would otherwise destabilize the truck. More importantly, they keep the fuel from “sloshing” *away* from the ‘Fuel pickup tube’ (part of the sender assembly, não listado) on steep inclines, which would cause the engine to suck air and stall.

3. Componente: ‘Fuel tank cap assy’ (1103010-50A)
Esse (Comp. 2) é o “Venting Logic.” This is not a simple “plug.” A sealed FAW J6P Fuel Tank would create a “vacuum” as the engine sucks fuel out, eventually collapsing the tank or starving the pump. This cap (Comp. 2) é a “Pressure-Vacuum” válvula. It allows air *in* (to replace the fuel being used) but prevents fuel vapor *out* (for emissions) and prevents fuel *splashing out* (para segurança). The ‘Diesel tank sticker label’ (Comp. 3) é a “Compliance Logic” componente, identifying the fuel type for safety.

Essencial 2: O “Structural Mounting” Lógica (Componentes 4, 5)

Este grupo “lógica” is to create a rock-solid, vibration-proof “prateleira” that the entire FAW J6P Fuel Tank rests on.

1. Componente: ‘Rear bracket assy-fuel tank’ (1101205C50A)
A lista pede dois (2) destes (Comp. 4). Este é o “Load-Bearing Logic.” A full 400L FAW J6P Fuel Tank can weigh over 350 kg (770 lbs). This ‘bracket’ é um serviço pesado, L-shaped steel “prateleira” that bolts directly to the truck’s main chassis frame rail. Esse “lógica” ensures that the tank’s entire weight is supported by the truck’s frame, not by the straps.

2. Componente: ‘Gasket-bracket’ (1101117C50A)
A lista pede dois (2) destes (Comp. 5). Este é o “Anti-Chafe Logic.” This is a simple but absolutely critical rubber or high-density foam “junta” that sits on *top* of the ‘Bracket’ (Comp. 4). Isso é “lógica” is to prevent *any* metal-on-metal contact between the steel bracket and the FAW J6P Fuel Tank. Sem isso “junta,” the constant, high-frequency vibration of the diesel engine would cause the steel bracket to “chafe” ou “rub” a hole directly through the bottom of the fuel tank, leading to a massive fuel leak and fire hazard.

Essencial 3: O “Critical Clamping” Lógica (Componentes 6, 7, 8-16)

Este grupo “lógica” is to “braçadeira” o FAW J6P Fuel Tank down onto its brackets, securing it against all forces.

1. Componente: ‘Strap assy-fuel tank’ (1101135C50A)
A lista pede dois (2) destes (Comp. 6). Este é o “Clamping Force Logic.” These are high-tensile steel bands that wrap *over* the FAW J6P Fuel Tank and bolt to the ‘Bracket’ (Comp. 4). Deles “lógica” is to provide the massive, downward “clamping force” que detém o 350+ kg tank in place during bumps, aceleração, and braking. They are often tightened with a T-bolt and nut, allowing for precise, high-torque clamping.

2. Componente: ‘Gasket-strap’ (1101134C50A)
A lista pede dois (2) destes (Comp. 7). Este é o “360-Degree Protection Logic.” Just like the ‘Gasket-bracket’ (Comp. 5), this rubber gasket lines the *inside* of the steel ‘Strap’ (Comp. 6). Isso é “lógica” is to prevent any “metal-on-metal” chafing on the top or sides of the FAW J6P Fuel Tank. Esse “Strap & Junta” + “Suporte & Junta” system creates a complete “cradle” that protects the FAW J6P Fuel Tank from all vibration and chafing.

3. O “Fixador” Lógica (Componentes 8-16)
Este é o “Hardware Logic.” This group contains all the ‘Hexagon flange bolts’ (Comp. 8, 9, 10, 11), ‘Hexagon nuts’ (Comp. 12), ‘Washers’ (Comp. 13, 16), and ‘Pins’ (Comp. 14, 15) required to mount the assembly. O “Flange Bolt Logic” provides a built-in washer for vibration resistance. The ‘Flat pin’ (Comp. 14) and ‘Cotter pin’ (Comp. 15) are a “Safety-Lock Logic” on the strap assembly, preventing the main T-bolt or pin from ever vibrating loose.

Essencial 4: O “Plumbing & Flow” Lógica (Componentes 17, 18, 19)

Este grupo final “lógica” is to manage the “fluxo” of fuel to and from the FAW J6P Fuel Tank.

1. Componente: ‘Inlet pipe assy – fuel tank to coarse filter’ (1104120-14BJ)
Esse (Comp. 17) é o “Suction Logic.” This is the single most critical pipe in the entire FAW J6P Fuel Tank sistema. Isso é “lógica” é ser o 100% airtight “straw” that *pulls* fuel *from* the tank’s internal pickup tube and delivers it *to* the primary (grosseiro) fuel filter/water separator. A tiny, pinhole “suction leak” here (from chafing or a loose fitting) is a catastrophic failure. It will cause the pump to suck *air*, leading to engine stalling, no-start conditions, and severe damage to the high-pressure injection pump.

2. Componente: ‘Inlet pipe assy – coarse filter to engine inlet’ (1104130-14BJ)
Esse (Comp. 18) é o “Clean Feed Logic.” After the fuel has passed through the primary filter (which removes water and large debris), this “lógica” pipe transports the “limpar” low-pressure fuel *to* the engine. It feeds the ‘FAW J6P Fuel Fine Filter’ (Chapter 24) and then the ‘Fuel Injection Pump’ (Chapter 23).

3. Componente: ‘Return pipe assy’ (1104250-14BJ)
Esse (Comp. 19) é o “Bypass Return Logic.” A High-Pressure Common Rail (HPCR) system *bypasses* a large volume of fuel to cool and lubricate the injectors and pump. Esse “quente” fuel cannot stay in the engine. This pipe’s “lógica” é ser o “return path,” collecting all this bypassed fuel and sending it back to the FAW J6P Fuel Tank to be cooled and recycled.
