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 The previous version was outdated and no longer supported.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

Petcock question

Husqvarna
AA Class
I was wondering if the entire husky line uses the same petcocks? Or more specifically if any other models use the same ones as the TE610?

thanks
 
Hmm, I guess no one knows...........

Well this is why I was asking.......

An idea taken from PowerCell in this ADV post though I had done something similar with TE610 tapping and threading the EFI plate. I've had two of the KTM/Husky style petcocks fail now, and I hate not having an easy quick release that stops the fuel flow. I mean I really hate having to deal with gas pouring out, so while this is overkill it's also damn convenient.

I took off one petcock and took some measurements and drew this up. Everything is in mm.

I might adjust the 34.5mm to be a touch wider, and I did adjust the o-ring depth to 1.2mm. The test prototype with the stock o-ring and a plug has been holding fuel just fine.

The part I ordered to work for this was from quick couplings LCD10004V - 1/4 NPT Valved Coupling Body w/ Viton seal and the matching part quick coupling LCD23004V - 1/4 Hose Barb Valved Elbow Coupling Insert w/Viton seals and they had the best prices I found anywhere. To give you an idea, fast by feracci sells the same parts for $29 each......

These are what I came up with using some aluminum and borrowing a friends older mill with homebrew DRO, and small lathe.

Putting one together, wouldn't want to do it while on the tank so I lugged it down with drywall screws to the benchtop.

In either case if the fuel like seems like it is too close to the header I'll get some Fuel Line Heat Shield

And since I was doing this with the 610 I went ahead and did the same thing for the crossovers on the 950SE too.
 
Are you using those fittings just for the crossover?
I ask because I have a few Cannondale dirt bikes and they used those type of fitting for the fuel system from the factory. Those fitting don't allow enough fuel to properly feed the fuel pump.
 
The crossover couplings are 1/4" npt to 1/4" barb. I would expect that to flow enough volume just fine. The coupling that is on the efi plate is 3/8"npt to 3/8" barb and has been in use for a couple of years now with no trouble. I don't expect any trouble using the 1/4" for the 950 as it's carbed and already had 1/4" fuel line.
