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 The previous version was outdated and no longer supported.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

Fuel Vent Leak Solution

I've been having a problem with my TE511 losing fuel since I bought it. I've replaced the stock valve on the vent line with another stock valve and it still leaks (about 6 oz on a typical hard ride). I am trying to think of a solution to this problem. I noticed the other vent that goes from the lower fuel cell to the upper one is directly in line with the vent line at the top near the fuel cap and only about a half inch of space separates their openings near the cap. I'm thinking that maybe pressured fuel from the lower cell is being forced through the vent line to the upper cell and shooting straight into the upper cell vent line. That line flows down to the valve where the fuel works its way past the valve and down the vent hose.

Is there a way to prevent the heated/pressured fuel from the lower cell from shooting into the upper cell vent line? I'm wondering if some type of valve on the hose from the lower cell could allow vapor to pass but hold back fuel? Obviously the stock valve is unable to do this. I wish the two hoses didn't line up so directly and closely near the cap. But it's just a theory I have that this is what is causing fuel to go out my vent hose.

Anybody have any ideas?
 
Never experienced this problem. Not with the stock setup or with the IMS.
I do like the IMS set up as the lower vent actually runs to the upper tank and vents out the cap like a traditional system.

Not helpful I know, but its all i got.
 
Can you use just the IMS tank and not the stock one? I wonder if I could just avoid using the stock one that way. Does the IMS tank still have to feed to the lower stock cell where the pump is?
 
Everything supplies the lower tank. You would have to relocate the pump to eliminate it and I can't see any real benifit to attempting that. I rarely fill the IMS unless I know I'm headed way out in the bush. At about 1/2 full the weight is hardly noticable for the average trail rider.

Again, with this system all vents are connected to the IMS tank so there is no risk of loosing fuel.
I'd take some pics but am presently away for work. The directions on their site outline it pretty well though.
 
oh, the vent hose from the stock tank feeds into the IMS. I didn't realize that. Yeah, that would definitely solve the issue. Thanks. Expensive solution though that shouldn't be required.
