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 The previous version was outdated and no longer supported.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

Trick to reconnect fuel line?

I'm not sure if my fuel line swelled up because of crappy gas, but I can't put it back all the way in on the connector tube on the throttle body.
I squeeze on the side, just like when I disconnected it, but I can still see about 20mm of the copper tube on the throttle body. The locking mechanism isn't getting past the small ridge on that tube.
Do you have to squeeze the sides just like when taking it off, or is there some other secret handshake?

On the plus side, I know my fuel pump works pretty well because the pressure at wide open made the line pull out. Good thing the bike didn't catch fire because there was furl everywhere!!
 
Have a good look at the brass tube and inside the end of the fuel line the ensure there is no debris stopping it going fully on. Also squeeze both white buttons on the hose end and check both retainers inside the hose are retracting when you squeeze the buttons.If those are good, and you are pushing the hose on straight, you very well may have some kind of damage to the hose. Mine requires firm pressure to reconnect, even with the buttons depressed.
 
Yes, the locking mechanism is chewed up. I can feel it click, but then when I pull on the hose it comes off. There is enough fuel pressure at wide open to cause it to come off.
In the end it doesn't matter because while experimenting with pulling I snapped the other end. So new fuel line either way.
Anybody knows how to separate the fuel line from the fuel pump assembly? It doesn't look that obvious from a customary look. Do I have to take the fuel pump out of the tank?
 
Thanks for that link. Worked like a charm.
It looks like that mechanism is a little bit beat up too. When you push the black plastic ring toward the fuel pump it depresses 4 small plastic tabs that hold the fuel line connector in, causing them to retract. One of the tab is broken.
I think the 3 remaining ones will still hold the line in place but this is causing my OCD to kick in. Any place to get that small plastic part from? The part list just shows the entire fuel pump.
 
Unfortunately the fuel line is back ordered at Halls.
But googling around I think I found where the 2 connectors come from. If not, they look awfully similar, down to the odd 7.89 mm sizing.
Only problem is minimum order is 1000 pieces. Group buy anybody? :D (did they even sell that many 630 in the US?)

You might contact Safari tanks (Just Gas Tanks) to see if they have any spare fuel lines for their tanks. It's longer than stock but you could make it work.

Looks to me like the minimum order is 100, so that may make them inexpensive enough and I'm sure many here would go in on that...myself included.
 
I can't read. It is 100 pieces, not 1000.
I'm on the phone with Safari Tanks (thanks DynoBob) and they do have some, but the guy I talked to needs to ask his boss about pricing (since they usually come with the tank)
If that doesn't pan out, show of hand, who would buy one set (or more) from me? I would have to order 100 of each, and would probably keep a few.
Depending on shipping I'm thinking it would probably be around $7 for one set, $3 for each additional set (shipping included) I'd probably have a bunch of leftovers to try to sell on ebay.
 
If they are, say, less than 10 bucks a set I'd buy at least two. Hell I might need a set now myself...mines not acting too normal so it may be about to crap out. Thank you for looking into this.
 
Here's another thread to check out:

http://www.cafehusky.com/threads/te-610-ie-fuel-fittings-help.287/

It suggests the fuel pump fittings are also used by Sherco, you may be able to contact Ryan Young to order a single replacement.

On my TE610 both of the petcocks on my fuel pump have been replaced - two different mechanics, at different shops, broke a plastic elbow and then replaced it with a brass one, suggesting this is a common point of failure.
 
Thanks Jon. I saw that thread earlier and tried to digest it. A bit hard since some of the references are old enough that the pics are not available anymore.
But looking at the pics that are available, the 610 has quick releases on the fuel pump side. The 630 doesn't:

So that's why they can use a sherco connector in its place:

and then just connect the quick release connector that looks like the one the 630 has on the TB side.
On the 630, we probably have something that looks like the short fat side with o-rings on the connector above, where you plug in the connector below.
I wonder if that's L-shaped Chinese connector can be printed on a 3-d printer. I have a coworker with one. I would need to provide him with a 3-d design. But I'm not sure these printed parts can withstand 70psi.

I assume the threading and taping might work if we can find an L shaped fitting that looks a bit like this, provided that we can find one where the non-threaded side fits inside the fuel line.
So this needs a but more investigating...

Got it. Yep. Quite different from the TE610. But if the TE630 pump has a plastic base it may not be possible to put in a brass fitting.

Here's my rather misfit pump:

Yes, the 630 plate is all plastic. Somebody should take one apart and report if there is anything metal to thread into :D

I know this is a years old thread, but did anyone ever order these parts? My 2008 SM610 has weak clips in the fuel line connectors and two of them will pull off by hand when completely seated, so i'm in the market for at least two new connectors.
