Cleaning the fuel injectors. Reading about a 0-ring screen kit? Don't see any screens on the videos?
Took off the o-ring on the top and cleaned the injectors off. It wouldn't seal in the tester fixture and i put the o-ring back on and melted it. Says to replace the top o-ring every time, the bottoms are good for reuse. The Dorman sets are a larger thickness? Haven't tried them in the rail yet. Order the OEM? Anyone know the dimension specs before I get out the calipers?

There's a tiny screen filter in the top of them. You take a screw, like a big wood screw (they have a tool made to do it but a screw works) and you screw it in and pull the filter out. New filters just push right in. The filters are small and cheap. I might have a bunch of filters if you are interested. I'll have to check. You are welcome to 4 of them.

Here's the kit, including screens....... for Yamaha outboard F150 model

Thanks Festus, ordered a kit.

Increased my google foo and saw the wood screw screen removal.
Searches showed dead links to the kits.

Cleaned them with carb cleaner in the tester. Will pull the screens and put them in the ultrasonic cleaner.

Cleaned all the injectors. Replaced screen filters. Bottom o-rings in kit not the right size, originals were fine.
Lessons learned
Stock top o-ring melted with the carb cleaner?? Black viton o-ring used in cleaner kit adapter.

Pump removal from tank requires care because or the float end stop plastic part is in the way. Used a feeler gauge for it to ride out the hole, video from a guy that broke his off. You can also reach a little screwdriver in to snap it loose from the pump, looked like a pain in the ass.

Quantum pump could have better bike specific info. None of the inlet filters fit in pump housing. Had to clean and reuse stock filter.

Get that thing back together and try this kit. Good for preventative maintenance.
