  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Do I have to drain the tank when removing on a fuel injected bike?

Sorry for the noob question, this is my first bike. All of my engine experience up to this point in my life is on 2 & 4-stroke remote controlled cars & airplanes.

I'm assuming that the connecting points on the fuel pump/tank are equipped with one way valves, but wanted to make sure before I ended up making a mess. Assuming the oneway valves are in place, do they tend to leak/drip?

Cheers
 
It may dribble a little out of the elbow, but as long as you turn off the petcocks before disconnecting the leveling tube and keep the tank upright you should be ok.
 
On my TE, the factory red plastic 90 is easily broke when removing tank and while setting it down. I use a vacuum cap on it due to the little bit of gas that dribbles out. I've only removed my tank when it was less than half full so it wasn't so much of a pain if it helps.
 
There is no stopcock on the efi bikes with the Italian motors and the fuel will all run out. Plus like 268fords said, the elbow is easily broken when removing the tank and the disconect thing is hard to do. You want that tank as empty as possible when removing it.

Sorry to confuse you.

On my '13 TE310, there are taps for the leveling tube, but the fuel pump in the tank has no valve.
It doesn't leak out, even when the tank is almost full.
Taking the tank off when full isn't recommended as you may have to fiddle underneath it to route the fuel pipe out.
I find it easier to remove the pipe from the FI, then remove the tank, complete with pipe. However, it's easier to refit the tank with the pipe on the FI, and put the pipe into the pump as you lower the tank down.

As has been said, fuel pump elbows are prone to breakage.
