2009 Hisun 700.... previous owner did a number of changes. This part is under the driver's seat but not attached to anything.
Is this the old fuel pump?
By Joel Goldsney
Wasn't sure exactly how to title this thread as I have a few issues with my newly acquired hisun UTV. Hopefully going to consolidate all the issues in one thread.
I purchased from a guy who had rebuilt the engine replaced the fuel pump as well as re-done the front end. He had the unit running and driving when it quit and would not start. He got frustrated and decided no more projects and sold it to me. Unit is in excellent condition physically.....hardly any scratches on the plastics. All in all its a good unit with the following issues/symptoms
1) Mis fire and stalling out when revved
Well as you can see by the title of the first issue I managed to get the unit running. Seems that the battery was very weak. I charged the unit and it fired up fine. The engine seems to stutter and misfire when revved and once the unit warms up it stalls out. I think it's a fuel issue as if I give it a shot of ether it starts back up.
Additional Note: Revving engine in Neutral seems to cause indication to flicker and occasionally the reverse light comes on which seems to kick in the reverse rev limiter. Have also hade this happen when driving around. Reverse Light flickers and revs get cut.
2) Fuel line configuration.
When he replaced the fuel pump he got creative with the tubing and removed the "small fuel tank"
Not sure what the purpose of this tank is but would love some pictures of a stock set up so I can put everything back together correct.
3) Issues engaging in gear
The unit seems to have issues going in to gear...I will move the shifter in place but the gear won't engage and the lights don't indicate correct. It takes a few tries to engage and sometimes it grinds a bit
4) Rack and pinion slipping
This problem is probably a simple replacement fix...when turning to the right with the vehicle not moving the steering just slipps and turns without turning the tire. I believe I just need to replace the rack and pinion but if there is something else please let me know.
Any insight or tips on resolving any of these issues would be much appreciated.

Ok I am hoping things aren't totally pooches
Side by side stalled out on my son and wouldnt start. Seemed to have very low vacuum draw on the pump and even when primed manually it wouldn't push much gas.
Have been wanting to check the valves any ways to see if they were off spec ( had been having issues with running rough)
I checked the valves....intake seemed a little tight and the exhaust very tight ( exhaust were brutal to get to )
Decided to check compression while I had the plug out....picked up a new compression tester as I couldn't find mine and was getting 0 compression.
Seemed strange so I pulled the tester out and cranked it with no plug to see if I was getting air movement. Seemed to be pushing air out of the plug hole fine....then heard a clunk sound and now the starter won't turn it over....it trys but it's like things are jammed.
Any thoughts on how bad I have screwed up?
I didn't think anything I did should have caused any damage.
I have a 2009 T2 joyner for sale, health and age issues have kind of sidelined me the past several years. The joyner has been in inside storage and is in very good condition with less than 3 K miles. I have made many mods from suspension to engine and frame. I am asking $7K or best offer. If interested contact me via email ([email protected]) and I will supply additional detail information.
