In the shop manual that is on this site you will find the schematics for the Ca model. (Look for the emissions control). One line is to the purge unit and the other is the vent line. Cap off the purge line. Some of them may still have their color markers on them still and that will further help identify which one.

Hi Troll,

Stock exhaust, checked that early on (actually had the entire thing off), rubber bushings appear to be in good order - mounts solidly with a little movement, which I suspect is how should be.  I did the motor mount bolt thing (I think you suggested it in my other thread), but couldn't hurt to do again (not like it takes a lot of time).  I just removed the rear rack tying the two saddlebag rails together, just to try something with regard to vibration through the frame.

I wish I could dismiss as character (and heck, may reach a point where I do), but it does feel like going over a washboard at lower speeds (and at lower rpm static).  Seems pretty harsh.

You're a gentleman and a scholar, again, much appreciated.

Vibration: How is your exhaust mounted? Factory stock will be rubber mounted, like the engine, and aftermarket is solid mounted...a good way to transmit vibes to your frame! Retorque the two motor mount through bolts to 32 lb/ft. Loosen them first, let the engine run for a minute or so, shut down and then tighten them... You WILL get some V-2 "character" transmitted, but the smooth high speed is just amazing....especially if you're a recovering H-D owner

Swapped the lines, added more gas, rode in to work today, all appears well (except for the vibration thing, but I'll keep working on it).

Just wanted to say thanks a ton for your help.

Got to be one of them.

Hi Troll,

There is a vent near the top of the tank, though I think that is outside the cap seal and just for slosh overflow.  I'll take a closer look when I get home.

The blue dot is the one I have capped off - in looking at your diagram, it possibly vents near the top of the tank.  If that is the case, it's worth trying to reverse it - cap the red dot (that is the one running gas to the ground), and venting the blue one.  Worth a shot.

And I really appreciate your help, sir.

Is there another available line that will vent the tank? Seal off the leaker and be sure you can get air inside.

Thanks again.

It is definitely coming from the red-dotted outlet (the line that had the same resistance as the single outlet original tank).  That line, as with the original tank, runs to the ground.

1st thing is to determine where the fuel is coming out when you fill it, second is to be sure you have an atmospheric vent that won't leak fuel

Sorry for the delay, this stupid work thing keeps getting in the way!

Should I try venting the second line to the ground?  Re-route it to the overflow vent to the upper part of the tank?

Thanks for your patience.

All you need is an atmospheric vent, fuel out, fuel in and a couple of overflow lines for the area under the cap and the sender "just in case"

Thank you.  That is very helpful.  Good to know on that sending unit line.  I was like, what the heck?

I have no problem with removing the tank.  The fuel does appear to be coming from the red return line which is routed down to the ground.  There is a line at the front of the tank up near the top which both tanks have (and I have hooked up), I'm guessing that's for slosh or overflow.

I noticed when swapping the pump both the the red and the blue have steel lines internally in the tank.

I'm studying the diagram - wonder what would work short of buying those evap components.  I'll have to think this through some more, and welcome any other thoughts.

Again, MUCH appreciated.

And I know I probably shouldn't worry about the bother thing - and get this is a forum.  It's just a weird one, and just my luck I ended up with a Cal-spec tank.

I know it's a pita, but you will have to raise the tank up enough to see under it and put in some fuel. The fuel gauge sending unit hose is an overflow if the sender leaks, and on mine, it just goes out to the atmosphere through one of the three hoses clamped by the oil filter. The hose at the rear of the tank is an overflow from the cap area. Here's a diagram of the california emissions hoses

Hopefully it's not a crack in the tank.
