Tenere 700: Fuel Pump Replacement Tea Bag Filter, Installation Guide & PurMotors (formerly Guglatech) Fuel Filter M220-06 ARM

 Tenere 700 Fuel Pump Replacement Tea Bag Filter 

Yamaha does not list any service interval for the fuel pump & related filter, but it is worth ensuring that the entire fuel delivery system performs as per spec & with proper pressure. At 35k km or 22k miles the tea bag filter on my 2014 Super Tenere 1200 ES was dirty resulting in pressure drop that affected performance & fuel economy...the change is subtle & progressive so difficult to ascertain without a pressure test or physical inspection of the fuel pump.

As with the Super Tenere 1200, Tenere 700 & other models Yamaha does not sell just the fuel pump tea bag filter, instead requiring buying the entire pump assembly (#BW3-13907-00), BUT Suzuki, who uses the same Mitsubishi UC-T35 fuel pump on their V-Strom 650 & other models does sell it, part #15420-44G00, which can be sourced via 3rd party suppliers on AliExpress.

2021 Tenere 700 Fuel Tank Removal

• The tank can be removed without complete removal of the front & side panels...see text in pics for instructions. 
• TIP:  Prior to disassembly take pics of fasteners, connectors, orientation of fuel pump or anything else of concern to assist with reassembly.
• NOTE:  Yamaha 2021 Tenere 700 service manual tank removal/fuel pump info & fuel tank parts list located at the end of this blog.

Draining the fuel tank

I used a power drill driven in-line pump to drain the fuel tank, but other methods/pumps exists, including disconnecting the fuel pump line from the injector rail & using the bike's fuel pump to drain the tank (check battery condition, put on charger if necessary).

Disconnect & reconnect of fuel pump connectors & tank air breather hose

• Do NOT stress the connected lines when lifting the tank
• Push the safety lock tab in to remove the electrical connector & ensure that the connector plug clicks firmly & fully seated when reinstalling...if you do NOT hear a click, try again...if NOT fully seated the connector may back out while riding cutting power to the pump & fuel gauge.
• Push the orange/brown fuel line safety lock forward to access the 2 side mounted push-in lock releases for removal of the fuel line connector from the pump & ensure that the connector clicks solidly on the fuel pump outlet then slide the orange safety lock back toward the fuel line for installation.
• After connecting the tank electrical & fuel connectors & air breather hose, but BEFORE reinstalling the tank & removed panels, ensure that the tank has a few litres of fuel & test operation of pump by turning on the ignition & waiting for the pump to fully pressurize before starting the bike.  If all is working ok, the bike should start & clear itself of any stumbles within seconds of running & idle normally. IF the bike stalls & won't restart, see pic & info further below in this blog about the placement of the fuel pump internal o-ring...it needs to be on the male protrusion/shaft of the outer pump housing when reassembling the 2 halves of the pump to maintain adequate fuel pressure...if it gets pushed to the bottom of the hole (female end) as seen in the pic referenced below it will block fuel flow, not hold fuel pressure & stall the bike.

2021 Tenere 700 Fuel Pump Filter Installation

• Clean the underside of the tank prior to removal of the fuel pump to prevent debris from entering the tank.
• If fuel not fully drained from tank lock fuel cap on tank & place a tire valve stem cap or firm fitting plug over the tank air breather fitting before inverting tank to prevent fuel loss (position the tank with the fuel cap elevated enough so that fuel does not reach it & depending on amount of fuel remaining in tank place the tank on a tray to catch any leaking fuel)
• NOTE:  Orientation in the pic below of the fuel pump for correct installation position to ensure proper connections & fuel float position (see pics of service manual further below)

Separation of 2 halves of fuel pump

• Gently lift the plastic housings over the locking tabs on 1 side & wiggle to unlock tabs, then repeat the process on the other side to separate the upper & lower halves. Use caution with sender assembly & float to not damage or bend.

• Remove fuel sender wires ONLY using a small flat head screw driver to push the connectors off the pins & to push back onto the pins.
• NOTE:  Wire order & do NOT pull on the wires.

• NOTE:  The orientation of the oem filter edge, in pic below, curved down to prevent blocking the metal fuel passage way.

Replacement vs oem fuel pump filter

• The replacement filter sock is slightly larger than the oem equivalent, however, the mounting base appears to be identical.
• NOTE:  That the replacement filter comes with a small press on star locking washer while the oem filter did not utilize one on the metal locating pin. Yamaha likely deemed it redundant as the pump housing presses up to the clip-on plastic guard atop the filter preventing it from dislodging, as seen in the above pic + if it were to dislodge it may damage the pump or impact performance. 

Reassembly of 2 halves of fuel pump

• NOTE:  The o-ring MUST be inserted over the corresponding male protrusion/shaft during assembly of the 2 halves of the fuel pump assembly. It may take a few tries as the o-ring increases resistance, I found that just placing it over the beginning of the protrusion vs fully seated all the way on preferable...your mileage may vary 😀
• During reassembly ensure that that the 2 halves of the pump assembly fit together properly aligned & squared to each other with all 4 locking tabs clicking firmly in place...if misaligned, the pump may not stay locked together & separate causing a malfunction in fuel delivery. 
• NOTE:  When installing the fuel pump into the tank, the correct orientation of the gasket is with the flat side inserted into the fuel pump housing & the raised edge facing the fuel tank (see service manual page further below).

Oem fuel pump filter with 32k km (~20k miles)

• Pic below of oem fuel filter shows what looks like small crystalized sediment...not sure if a breakdown of filter material or a foreign substance. I have been using a Guglatech M220-06 ARM fuel tank filter for 31k km & it had small traces of a chalk like material inside it that was able to be removed once the filter was dry.

Interior view of my fuel tank @ 32k km (~20k miles)

• Interior view of my tank with the filler neck at the top shows a small amount of a chalk like material, other than that it was very clean with no film or gunk present.
• NOTE:  That the inner edge of the tank fuel pump opening is very sharp.

2021 Tenere 700 Service Manual Tank Removal & Fuel Pump Info

NOTE:  The correct orientation of the fuel pump gasket is with the flat side inserted into the fuel pump housing & the raised edge facing the fuel tank + Yamaha specifies using a new gasket #IRC-24486-00 (see service manual page below).

Post Filter Replacement Observations

Post-filter change the bike started immediately settling into a smooth & even idle & during the road test ride observed crisper, more immediate throttle response & urgency throughout the rpm range with slightly higher onboard instant fuel mileage numbers. This is a similar result to what I observed after changing the fuel pump filter on my 2014 Super Tenere 1200 ES @ 35k km. Changes in performance, such as reduction in power, decreased throttle response & increased consumption, due to degradation in fuel flow, pressure & contaminates reaching the fuel injectors are difficult to recognize as it is gradual, but clean filters restore fuel flow, pressure & filtering which are impactful to injected systems.  

PurMotors (formerly Guglatech) Fuel Filter M220-06 ARM

The Guglatech Fuel Filter M220-06 ARM is regarded as providing outstanding fuel filtration available in a reusable format via a sock that drops inside the neck of the gas tank & filters out contaminates such as dirt, sand & water every time you fuel up helping to extend the service life of the fuel pump/filter & related components. Sold in the US by BestRest Products as well as other world wide retailers.
