  • 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 The previous version was outdated and no longer supported.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!

Siphon fuel to pull tank?

On the EFI bikes like 08 TE450, is it necessary to siphon all the fuel outta the tank before pulling the tank? Will it run past the fuel pump when the hose is disconnected? Any neat tips or tricks guys?
 
No need to siphon any fuel when removing your fuel tank. Just disconnect the fuel line and take it off. Be careful though, the plastic fuel line coupler has been known to break.
 
If it's empty or nearly, it's easier to hold up and thus easier to get to the dis-connector, which until you've done it a few times is a little difficult (and hard to see without some light.) It takes a little finger strength to squeeze and pull the line apart.
 
OK, thanks. Yeah, it's a bit fiddly. I got it, but it took a while. Is that plastic fitting screwed into the housing? It seems a little loose but I didn't want to turn it and break it.
 
I have a '08 efi 610, but i think its the same on all the efi bikes.

Most folks seem to be doing it the hard and messy way.

Try this:

Disconnect outside fuel line at the tank.
Disconnect inside fuel line either 5 inches down where the 90 degree elbow is, or on the left side of the bike at the brass fitting by the efi unit. Both are easy to access. Both have built in one way valves, so fuel wont leak all over ya. Thats key. Much easier on the fingers, too.
Plus its far less likely to stress/break the weak plastic male fittings at the fuel pump.

Now you can easily and safely lift up the tank enough to unplug the electric connectors.

Of course you must take out the allen head, the seat, vent and overflow lines up front, etc. etc. first. Turn off the gas too!

I remove the cross over line on the left side.

Hope this helps. It took awhile, but after staring at the bike and saying 'there must be a better way' i think i figured out how this tank was designed to be taken off. Most folks are doing it the hard/messy way.

Dont drop that tank, dont balance it on the frame, and take care when setting it down, those little plastic male fittings break.

Uptite Husqvarna has a great fix. Brass male fittings. Very nice insurance for a trail side catastrophy.
 
Fuel WILL dribble past the pump and out of the elbow continuously once disconnected.

Method #1- I put a vacuum port cap on the elbow and set the tank where ever I need to with no issues.

Method #2-You can remove the tank and set it with the pump higher than the fuel level such as lean it against a wall or something if you have the space and coordination to do that. If gas cap gasket is shot or not seated correctly, you get a leak from that using method #2. HTH

P.S.-As previously mentioned, be very gentle with that red plastic elbow.

You're right. Best to orient the tank (after removal) so that there is no chance of leak. IIRC George puts them on end.
