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 The previous version was outdated and no longer supported.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

Someone finally tried an external fuel pump

Wow, cool for the 610/630 because they have a fuel return, to bad for the 250/310/450/510 because they do not have a return and no way to deal with the extra fuel.

Yeah, you'd definitely have to plumb in a regulator, this pump flows way too much for a dead-headed system.
 
Had the tank off my 630 today and did not see a fuel return line(One line leaves the tank). Isn't the pressure regulator built into the pump/filter assy. in the tank and if so wouldn't you have to install a regulator and return line after the external pump and plumb it back to the tank for regulation? There must be a small reasonably priced pump out there that can be installed in the tank same as original and use existing regulator!

If you only have one line, then you're screwed. You have to get a pump that is reasonably similar in PSI and flow. Nobody publishes the data you need to find. There are OEM's that make the pumps, but you gotta buy hundreds of units. The pump I used is easily overwhelming the fuel rail, but with the external regulator the excess is just returned to the tank. You could certainly hook up an external regulator, but then you run into some space/fitment problems.

Kudos for the work you have put into this!:thumbsup:


+1 on that Xymotic

It will be great to see how this plays out over the next few months because if your trial is a lasting success I can see an IMS tank in my future.

Yeah, we'll see if I need a new engine in a month:D
 
looks like you spent a ton of time, learned alot and came up with an imaginative system that appears to work and maybe saved a little money. But for all that I personally would have ponyed up the bucks, bit the bullet and spent more time riding or doing other things with all that effort. But good on you anyway....

It's not really about the bucks (entirely), the goal is an IMS tank. George is working on a sub-tank to move the stock pump into. However it is still going to be mounted beside the motor and somewhat vulnerable, you're "stuck" with the OEM pump if it dies again, and it's not available yet.


So the only other solution was to wait a week for a stocker for $500. I spent $300 and got it working in three days.

PS it's raining like crazy right now, so... And FWIW, I have $36 left in my checking account. SO ponying up the bucks wasn't an option. It was this or order the romanian one on ebay for $200 and wait another week.
 
Keep us posted on how the pump is working for you. Thanks for taking the time to post your results! This will be good to know when its time for a bigger tank! :thumbsup:
