Replacing EFI fuel pump in a Kymco LIKE200i

[Stig / Major Tom]

The stock LIKE200i fuel pump has "no serviceable parts" according to my manual.
The 0 ring is supposed to be replaced each time you remove the pump from the tank.
No one sells the giant 0 ring - it is attached to the new $+200 pump assembly.

The pump must be eased out of the tank with some effort (like a cork in a bottle) and I returned it with a bit of silicone lube all
around.  Taking the measurements of the stock pump and after a phone contact with the tech. - I purchased a replacement 30mm HIGHFLOW pump. (ebay add said it would fit a Suzuki motorcycle) It's been working great in my 2012 LIKE200i for 9 years.

This one? Pumps have changed since my installation. Phone or email to confirm the size for fitting into KYMCO holder. 30mm X 70mm

Basically 'plug-and-play' Take a photo if need be to get all connections back in proper places.
Match the wires and hoses, place in the stock KYMCO pump holder and reinsert it back into the tank. Bolt it up and check for leaks.


All kinds of pumps are available - I paid a bit more for the HighFlow as I don't want to repeat this procedure!

Stock pump is in this metal and plastic holder.....which you will re-use!

The O-rings are available from hydraulic parts service shops like Freudenberg Seals: http://or.ecatalog-na.fst.com/catalog/OR.htm?_ga=2.111495235.632739621.1568500950-1098743817.1568500950

They're all over the world, they have a list of dealers on the above website.

Thanks, if mine ever leaks I'll visit them.

I have the exact same scooter as you and made the mistake of letting it sit for a year. Initially it fired right up and I took it for a short 3 mile test drive, at the last 1/4mile it almost didn't make it. The fuel pump was kicking on as it should and I pulled the line and flow looked good, I assumed there was some varnishing in the injector and replaced it  (fyi you can get them on ali express for less than $30) but after installing it the problem remained (would fire up but no power then would slowly deteriorate idle and die). I cut the supply hose to the injector and installed a pressure gauge (which is what I should have done to start with) and found that I only had about 22psi.  Searching for a new pump brought me to this thread (so thanks) I'm contacting the vendor to be sure the newer model will still work before ordering.
Here's the link to the injector if anyone needs it: https://www.aliexpress.com/item/32880547383.html?spm=a2g0s.9042311.0.0.52f44c4ddiKsJ6

Also a little more info, when I pulled the pump apart today, I think the entire problem was the poor quality rubber hose they used inside the tank, it was completely deteriorated and obviously leaking through the hose itself, had I caught that before I pulled it all apart I probably could have just put a new section of hose on it...but, the filter element was also deteriorating and falling apart so it probably ingested some of that too..

At the risk of sounding like a clueless dope, how do you know when the fuel pump needs replacing?

[Stig / Major Tom]

My reply is that for 99% of us, neither the fuel pump nor its filter, will ever need replacing or servicing for the life of our ownership.
Use decent gas, check the valves, replace the plug, and change the oil - and you'll be good for many miles and years.
The LIKE200i is one Kymco model which gives the owner years of reliable riding.

Just as a matter of interest - to my understanding the filter element on Icac_man’s fuel pump was falling apart within 6 years (2013 model).
Are loose filter elements available , or does it mean the complete unit needs to be replaced because loose filter elements are not available ?

As you can see from the above photos - filter is separate from the pump - and must be attached. So, would imagine these can be found if needed.
I've only had 4 different scooters, from 4 different major manufacturers* - and none of the service manuals which accompanied the scooters mention the fuel filter in the periodic maintenance schedule.

a good portion of the deterioration is my fault, had I regularly kept fresh gas in it I doubt this would have been a problem for quite a longer while. The rubber hose that jumps the actual pump output to the tank outlet port may be the caveat to that, it was extremely gummy and I could pull it apart with my fingers...maybe just a bad batch of hose..
You can see in the picture some of the remaining "screen" material laying on the bench, all of this just fell off the filter as soon as it was removed from the tank and dried a bit.
Also added a picture of what remains of the jumper hose..

Quantum HFP-389-U fuel pump installed yesterday and works great.

Quantum HFP-389-U fuel pump installed yesterday and works great.

Good deal.
I think HighFlow is now Quantum.
In any event. ..I also did not go with the cheapest pump out there.
Glad you got it running again.

I'm grateful for your original post...it made finding a new pump much easier!

Thanks!
Lest my OP is understood to be an
 ongoing problem with the LIKE200I fuel pumps....

Backstory:
1) Not good dealer support
2) my 2012 (made) LIKE200iLX developed bad stumble when cruising at steady 30mph.
3) dealer couldn't reproduce it
4) I started replacing parts, incl fuel pump
5) Kymco diagnostic tool lent me, by Crossbolt, proved TPS faulting
6) Kymco customer representative told dealer to buy the Diagnostic Tool and put a new Throttle Body in my scooter . Under warranty. Free. Whole process took months.

7) great running scooter for 6 yrs!

Yes, perfectly good orig Kymco fuel pump in drawer...alongside an injector & a coil.😊

6) Kymco customer representative

Where does the average Kymco owner find a "Kymco customer representative"?
