Im in the same boat as you, when you look at the manual or the replacement part, the lower fat hose is a high heat hose, I spoke to a mechanic who in Canada is supposed to be the whos who for these machines he said it attaches to the exhaust system, mine looks like it broke off - but in the same breath he said they just take them off and seal off the vacuum hose portion (did not get exactly how he did that so bought a new one just to be safe) so I will look this weekend to see if i can find the exhaust port that it supposed to go to and see if that fixes my no idle issue - it was running fine up until 2 weeks ago then just wouldn't idle.  Put in new carb, gas line, filters the works, waiting on ignition cable and fuel pump just to be safe to see if that works.

Thanks

well.... mine is definitely not attached and it idles fine....

If there is an exhaust port that this attaches to please take a pic and post....I am getting occasional fumes in to the cab and if there is an open port that would prob be the source.

I plan on removing it completely as from what I have read it was there to meet environmental standards.....

(Can't remember where I read that but since mine seems to be running fine without it I will go with the assumption that it is not critical for operation)😀

If you lift the back, look at the exhaust and just above it is the port here is the parts breakdown - the guy told me to remove it, seal it with smaller length screws and plug the hose or

remove it completely - my guess is that i just take out the 3 way connector, connect it directly to the fuel pump and see what that does.

Was the Canada guru named Aaron? He's been helping me with TONS of advice on the Hisun owner's group on Facebook. Wealth of Hisun knowledge. :)

      2016 Hisun 500 runs rough no power
      By CapnWalleye
      Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
      - drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
      - replaced the fuel injector.
      - disconnected the battery (several times) to allow the module to reset.
      - set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
      - replaced the battery.
      - replaced the O2 sensor.
      Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

      Code Reader for Delphi MT05 Coleman UTV 400 Hisun
      By Homeowner A
      Is there a code reader available for the Coleman UTV 400?  I tried using the HUD ECU Hacker software and cables/adapters but no luck OBD to delphi 6 pin and KKL VAG as well as ELM327.  Will not connect.  I was able to get it to connect randomly a couple of times, but haven't been able to since.  I was able to clear and read the codes briefly.  I'm aware of the Tiny Scan 301 but it doesn't seem to be readily available.  There's a few out there but they are expensive.

      2013 Hisun 800 Please Help Wiring
      By Marie
      Hello, we recently got a 2013 Hisun 800 as a little project for my husband and I to work on. Turns out the guys before us loved the mud anyway. We have replaced the stator and now going to do the Rectifier but here is the hold up as seen in the picture. There are tons of wires going to the battery. I cant seem to find anything that shows what wires should, or shouldn't be attached to the battery or where these 2 plugs go. if someone would please take some pics or share knowledge to where they go I would appreciate it greatly.

      Can’t figure out what part I’m missing
      By Grant
      I recently bought an axis 500 and it’s missing a box or something the plug is L shaped I’ve looked through the wiring diagrams and still can’t figure it out. The plug is located right near the battery housing
