Could not find specs for the Like but fuel pump pressure for the People GT 200i is 3 BAR or 45 PSI.
The pressure I posted is actually from the DT300i service manual! Figured it would be close enough since all the fuel pumps seem the same...

Whiskers, you GOT this! That fuel pump is so easy to get to. I will bet there is a small piece of trash stuck in the relief valve bypassing fuel back to tank. That's probably where the bubbles originated!

In case you have to investigate and/or replace the LIKE's fuel pump:

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 advert. said it would fit a Suzuki motorcycle) It's been working great in my 2012 LIKE200i for 7 years.

KYMCO holder accepts a pump this size.... 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!


New HighFlow pump installed in holder.

There! Stig's way better service manual than Kymco!

The 200 bucks from Kymco is because they list the whole assembly. Stig did the legwork to find just the pump! He cheapo Joe like me! He's a genius!

Quick question on fuel pressure wondering if anyone knows. The small hose from the pump to the outlet inside the tank was deteriorated, I replaced it and now my fuel pressure is perfect while the pump is running when you turn the key on, as soon as the pump stops running the pressure drops back to zero, is it supposed to do that?
Thanks

See? You the genius! We were all hot for you to replace the pump and YOUR investigation shows a $.98 hose is the culprit!

Yes, the pressure drops to zero whan the pump shuts off. Normal.

So happy for you finding this! Now you have been farther into the fuel system on this model than anyone here! Your discovery leads to one more thing on the troubleshooting checklist. This feedback is vital since this system is typical of most EFI setups on these types of machines. Your results SHOULD be in the service manual!

Curious here big blue - what manual is that from?
Does not look like either my printed cyclepedia or my online version.
Thanks, Stig

It's an old online factory PDF manual that was available for free. I have a copy on my computer.  ;)

Ok everyone I put the new fuel pump in, good pressure, did all the resets etc. it will crank and start if I hold the throttle wide open and then it will run as long as I have the throttle almost 1/4 to 1/2 turn but will not idle, I’m not an expert but something is telling me injector, I took it off again and cleaned it, so that’s where I am.
I just know by the end of the weekend this thing will be working and I will have the wind in my hair once again.

Can you button it up and ride it very briskly near enough to your house that if it dies it won't give a stroke if you have to push it home?
Perhaps that poor scooter just needs some exercise....and maybe a fresh tank of SHELL premium gas to flush out your injector and fuel line?
If it does throw an embolism. ...you need to be close to the house......
Things are looking good!
Meanwhile we'll look into "scooter won't idle"
