Honda Fuel Pump Hose Feed 2007-2014 Rancher 420: The Complete Guide to Replacement, Diagnosis, and Maintenance
If you own a 2007-2014 Honda Rancher 420 (TRX420) and your ATV is struggling to start, stalling under load, or showing signs of fuel delivery problems, the fuel pump hose feed is likely the culprit. The feed hose inside the fuel pump assembly is a common failure point on these models, and replacing it is a straightforward repair that can save you from buying a complete pump assembly. This guide will walk you through everything you need to know about the fuel pump hose feed for your 2007-2014 Honda Rancher 420—from symptoms and diagnosis to replacement steps and the best aftermarket options available.
What Is the Fuel Pump Hose Feed and Why Does It Fail?
The fuel pump hose feed is the internal rubber hose that connects the fuel pump to the outlet inside the fuel tank. On the 2007-2014 Honda Rancher 420, this hose is part of the complete fuel pump assembly (OEM part number 16700-HP5-602) . Over time, exposure to ethanol-blended fuels causes the rubber to degrade, crack, or soften, leading to fuel leaks inside the tank or a loss of fuel pressure. This is a well-known issue in the off-road community, and it is one of the most common reasons owners need to replace the entire pump assembly.
The OEM fuel pump assembly for the 2007-2014 Honda Rancher 420 includes the pump itself, the hose feed, seals, and strainers. The original part, 16700-HP5-602, is used across multiple models: the TRX420 Rancher (2007-2014), TRX500 Foreman (2012-2013), and TRX700XX (2008-2009) . When the feed hose fails, the pump may still work, but it cannot deliver fuel properly to the engine.
Signs Your Fuel Pump Hose Feed Is Failing
You do not need to be a professional mechanic to spot the warning signs. Look for these symptoms:
- Hard starting or no-start condition – The engine cranks but struggles to fire up, especially after the ATV has been sitting for a while. This is often the first sign of a failing fuel pump hose feed .
- Stalling under load or on hills – When you accelerate or climb, the engine loses power and stalls. This happens because the cracked hose cannot maintain adequate fuel pressure .
- Sputtering or hesitation during acceleration – The ATV feels like it is running out of gas even when the tank is full .
- Whining noise from the fuel tank area – A failing pump or a restricted feed hose can cause the pump to work harder, producing a high-pitched whine .
- Fuel smell near the ATV – If the hose is cracked inside the tank, raw fuel vapors may escape, especially when the tank is hot.
If you notice any of these symptoms, especially on a 2007-2014 Honda Rancher 420, the fuel pump hose feed should be your first suspect.
Diagnostics: How to Confirm the Hose Feed Is the Problem
Before ordering parts, you can perform a few simple checks to confirm the fuel pump hose feed is the issue:
Check fuel pressure – The easiest way is to use a fuel pressure test kit. Connect the gauge to the fuel line on the engine side. For the 2007-2014 Rancher 420, the operational pressure should be between 43-68 psi . If the pressure is low or fluctuates, the pump or hose feed is likely compromised.
Listen for the pump – Turn the key to the "on" position without starting the engine. You should hear a brief whirring sound from the fuel tank area. If you hear nothing or the sound is weak, the pump may be running dry due to a damaged feed hose.
Visual inspection – If you have removed the pump assembly from the tank, examine the rubber hose that connects the pump to the outlet. Look for cracks, soft spots, or swelling. On ethanol-exposed hoses, the rubber may feel sticky or gummy .
Inspect the tank seals and strainers – The pump assembly includes multiple seals and strainers. If the hose is failing, the seals may also be degraded. A complete replacement kit typically includes new seals and strainers, which is a good idea to replace at the same time .
Replacement Options: OEM vs. Aftermarket
When it comes to replacing the fuel pump hose feed on your 2007-2014 Honda Rancher 420, you have two main paths: buying the complete OEM assembly or using an aftermarket replacement.
OEM Honda Fuel Pump Assembly (Part Number 16700-HP5-602)
The original Honda part is available through dealers like Honda Parts Nation. The pump assembly itself retails for around $198.06, and the individual parts like the feed hose (Honda part 17570-HP5-A11) are sold separately . The OEM feed hose is listed at $74.44 . However, buying the hose alone does not include the pump, seals, or strainers, so you may end up spending more than a complete aftermarket kit.
Aftermarket Fuel Pump Assemblies
Several aftermarket brands offer direct replacement fuel pump assemblies for the 2007-2014 Honda Rancher 420. These kits are designed to replace the OEM 16700-HP5-602 and come with everything you need in one box. Most aftermarket options are priced between $79 and $112, which is significantly cheaper than the OEM pump alone . Complete aftermarket kits typically include the pump, hose feed, seals, strainers, and wiring connectors, making installation plug-and-play .
Note on quality: Not all aftermarket pumps are created equal. Some users report that cheaper unbranded pumps fail after a few hours of use . It is worth investing in a reputable brand with a proven track record.
Step-by-Step Replacement Guide for the 2007-2014 Honda Rancher 420
Replacing the fuel pump assembly on a 2007-2014 Honda Rancher 420 is a job that most DIY mechanics can handle in under an hour. Here is how to do it:
Step 1: Relieve fuel system pressure. Locate the fuel pump relay or fuse and remove it. Start the engine and let it run until it stalls. This releases the pressure in the fuel lines and prevents fuel spray when you disconnect the hoses .
Step 2: Remove the seat and access the fuel tank. On the Rancher 420, the fuel tank is located under the seat. Remove the seat bolts and lift the seat off.
Step 3: Disconnect the electrical connector and fuel lines. Unplug the wiring harness from the top of the pump assembly. Use a fuel line disconnect tool to release the quick-connect fittings. Have a rag ready to catch any residual fuel.
Step 4: Remove the pump assembly from the tank. The pump is held in by a locking ring or bolts. Use a spanner wrench or screwdriver to turn the ring counterclockwise. Lift the pump assembly straight out of the tank. Be careful not to bend the float arm or damage the tank.
Step 5: Disassemble the old pump. Remove the old hose, seals, and strainers from the pump body. Note the orientation of the hoses and wiring before disassembly.
Step 6: Install the new pump assembly. If you bought a complete aftermarket kit, the new assembly comes pre-assembled. Simply drop it into the tank, align the tabs, and tighten the locking ring. Reconnect the fuel lines and electrical connector.
Step 7: Prime the system. Turn the key to the "on" position for about 5 seconds, then turn it off. Repeat this cycle 3-4 times to allow the pump to build pressure. Check for leaks at the connections.
Step 8: Start the engine. If the engine starts and runs smoothly, the replacement was successful. If it still stalls or hesitates, double-check the hose connections and ensure the pump is receiving power.
Maintenance Tips to Extend Fuel Pump Life
Preventative maintenance is the best way to avoid future fuel pump problems on your 2007-2014 Honda Rancher 420. Follow these simple guidelines:
Keep the fuel tank at least a quarter full – Fuel helps cool the pump and prevents overheating. Running the tank low can cause the pump to overheat and fail prematurely .
Use high-quality fuel – Avoid low-grade gasoline that may contain water or contaminants. Ethanol-blended fuels are harder on rubber components, so using a fuel stabilizer can help protect the hoses and seals .
Replace the fuel filter regularly – A clean filter protects the pump from debris. On the Rancher 420, the filter is part of the pump assembly, so it is replaced when you swap the pump .
Inspect electrical connections – Corroded or loose connectors can cause voltage drops that wear out the pump. Clean the terminals with electrical contact cleaner if needed .
Listen for unusual noises – A whining or buzzing pump is a warning sign. Address it early before the pump fails completely .
