Diy External Fuel Tank For Honda Eu2000i: A Step-By-Step Guide

how to make external fuel tank for honda eu2000i

Honda does not manufacture extended run tanks for their generators due to liability issues. However, external fuel tanks for Honda generators are available from third-party sellers on e-commerce platforms like Amazon and eBay. These tanks are designed to provide fuel for Honda generators like the EU2000i and can be made from standard marine parts, with some components sold by Honda. The process of creating a custom external fuel tank involves modifying the fuel cap and connecting the tank to the generator using fuel lines and fittings designed for marine fuel systems.

Buying an extended run kit from Honda

Although Honda does not make an extended run tank for their generators, they do sell an extended run kit. This kit can be purchased on eBay, where there are several Honda extended run kits available.

The Honda extended run kit includes a fuel cap. It is important to note that Honda has changed their fuel cap design, and the vent no longer goes through the top, making it harder to modify for extended run. The older Honda fuel caps may not have the same threads as the modern ones.

The extended run kit is a good option for those who don't want to deal with the hassle of fuelling their generator every six to ten hours. With the kit, you can run the generator for six to eight hours, then shut down, cool off, and refill from external storage.

Additionally, Honda sells external fuel systems for their outboard motors, and some of the parts are also compatible with the Honda EU2000i generator.

Using an external fuel system for outboard motors

An external fuel system can be a useful addition to your boat setup, especially if you travel a lot and want to avoid frequent refuelling. Honda does not manufacture extended run tanks for their generators due to liability issues, but they do sell external fuel systems for their outboard motors.

Parts and Setup

The external fuel system consists of a fuel tank, fuel lines, and gas caps. The fuel tank is typically made of metal, aluminium, or stainless steel and is located in the lower part of the boat. Its size depends on the vessel's size and fuel requirements. The fuel lines are made from Mercury 5/16" EPA-approved premium fuel line with a marine-rated fuel connector from Honda. The gas caps are manufactured using a computerized CNC machine from a single solid piece of 6061 T6 aluminium.

To set up the external fuel system, you will need to connect the fuel tank, fuel lines, and gas caps to the generators. The fuel fittings are quick-release, so no tools are needed, and it only takes about 30 seconds to connect everything. Make sure to keep the original gas caps for your generators and use the new ones provided with the external fuel system.

Considerations

When using an external fuel system, there are a few things to keep in mind. Firstly, ensure that the fuel tank is adequately secured and vented to prevent spillage and ensure proper operation. Secondly, the Honda generators have a fuel pump, so if the internal generator fuel tanks are full and the external tank is connected, the fuel will flow from the external tank to the generators as the internal fuel level drops. Finally, you may need to loosen the cap during use to offset pressure buildup in the tank.

Using a dual-run system with a squeeze bulb

Honda does not manufacture an extended run tank for their generators, but they do sell external fuel systems for their outboard motors. However, you can purchase a dual-run system with a squeeze bulb from a third-party seller on eBay. The seller assembles the system themselves and is based in the US.

The dual-run system with a squeeze bulb includes the following parts:

  • One gas cap for each generator (keep the originals)
  • One dual-run hose that connects to the fuel tank
  • Two fuel lines (one for each generator)

The fuel fittings are quick-release, so no tools are required for assembly. It takes approximately 30 seconds to connect the system to your generators. The gas caps are manufactured using a computerized CNC machine from a single solid piece of 6061 T6 aluminium. The fuel lines are made from Mercury 5/16" EPA-approved "Premium Fuel Line" with a genuine marine-rated fuel connector from Honda.

The squeeze bulb is used to prime the fuel line from the external tank to the engine. The bulb helps to draw fuel from the external tank to the generators, ensuring a continuous fuel supply. This setup allows the generators to run for an extended period without the need for frequent refuelling.

Buying a custom fuel cap on Amazon

Honda does not manufacture an extended run tank for their generators, possibly due to liability issues. However, external fuel systems are available from third-party sellers on eBay and Amazon.

When purchasing a custom fuel cap for your Honda EU2000i on Amazon, it is important to consider the following:

Compatibility

Ensure that the fuel cap is specifically designed for the Honda EU2000i model. Check the product description and customer reviews to confirm compatibility. Some fuel caps may only be compatible with certain Honda generator models, so it is important to verify before purchasing.

Quality and Material

Look for a fuel cap made from high-quality materials, such as CNC aluminum alloy. This ensures durability and a secure fit. Check customer reviews to gauge the overall quality and longevity of the product.

Ventilation

Consider a fuel cap with a built-in breather valve or ventilation system. This feature helps normalize pressure within the tank and prevents a build-up of pressure, which can be an issue with the Honda EU2000i.

Price and Reviews

Compare prices between different sellers and products to find the best value. Read customer reviews to gain insights into the quality, performance, and durability of the fuel cap. Pay attention to any reviews mentioning leakage or ventilation issues, as these are crucial factors for fuel caps.

OEM and Aftermarket Options

You may find both OEM (Original Equipment Manufacturer) and aftermarket custom fuel caps on Amazon. OEM caps are produced by the original manufacturer and are typically more expensive. Aftermarket caps are made by third-party companies and may offer more affordable options, but be sure to check their compatibility and quality carefully.

Examples of Custom Fuel Caps on Amazon

Amazon offers a variety of custom fuel caps, such as the EuroJamb hdesaracingcap Custom Racing Gas Fuel Cap Assembly, which is designed for dirt bikes and motorcycles. Other options include the JOYYANGFANG CNC Aluminum Gas Fuel Tank Cap and the E-riding Gas Fuel Tank Cover Cap, both of which feature breather valves and are compatible with a range of dirt bike models.

By considering compatibility, quality, ventilation, and customer reviews, you can make an informed decision when purchasing a custom fuel cap for your Honda EU2000i on Amazon. Remember to prioritize safety and always follow the manufacturer's guidelines when modifying your generator's fuel system.

Using a fuel extender

The Honda EU2000i generator has a limited fuel capacity, which can be addressed by purchasing an after-market extended run fuel tank. These tanks are available on Amazon and eBay, with prices ranging from $10 to $473.99.

To set up a fuel extender, you will need to purchase an extended run kit, which includes the external tank, fuel lines, a fuel cap, and quick-release fuel fittings. The kit should also include a \"squeeze bulb\" to prime the fuel line, although this may not be necessary for the Honda EU2000i as it has a fuel pump.

When using an extended run fuel tank, there is one important modification to make. The original Honda gas caps have plastic retainers that need to be removed and replaced with the extended run caps provided with the tank. Remember to put the Honda caps back on during transport for safety.
