How to check fuel flow on outboard

This video will show you how to check the fuel delivery through your outboard motor. Watching this you can check fuel flow all the way from the tank to the carburetor bowl to determine if you have a fuel delivery problem or if the carburetor itself is gummed up.

A common mistake people make when attempting to prime a fuel line from a previously empty fuel tank is forgetting to hold the primer bulb in a fully upright position while squeezing the bulb. This enables the valves in the primer bulb to function properly. Another often missed step in systems with large fuel tank line filter systems is neglecting to fill the canister with fuel after changing the filter. If you leave the canister empty you will be forced to squeeze the primer bulb many times to fill it before fuel will actually be delivered to, the engine.

Great video, professional and right to the point. Unlike others on YouTube that play music in the back ground and waste time wanting to hear themself talk.
Keep posting! 👍🏻

I don't do a lot of work on engines, but when I do, I usually get a refresher and I'm always reminded of how intuitive they really are... fuel oxygen spark.
Thanks

Thanks for doing this, the store told me I should be able to just squeeze the pump and fuel would come out, didn’t work. Watched your video and it made it easy to see that you need to push that connector in for fuel to come out. Did that and it confirmed it was working. Saved me an unnecessary 75 purchase of a new one

1995 60hp Tracker cranked no start (sat idle for a year) this video showed me how to check for gas to carburetor, opened the bowl drain, pumped the gas ball to flush out old gas, started right up. ( already had put fresh fuel and enzyme additive in tank) .
Thanks for taking the time to show me how to trouble shoot.

One of the best explanations of outboard motor fuel flow, excellent job😊

This video is the most helpful video on YouTube. Thank you so much 🙏

Nice video! My 8 hp tohatsu wouldn’t idle. Took off the carbs and cleaned out the jets. Put back together and it ran perfect.

I see why you have 1.5 M views, calm commonsense advice. Well done, subscribed.

Man you are the best. So to the point and clear.

bought a little boat with a 35hp motor, one of the things that i just noticed while unsucesfully trying to start it was the one way pump was installed in reverse and i realized that during this video lol

Very well explained. I tend to jump in too fast and miss little essential checks.

Your boat motor videos are the best on the web. I've learned a ton from you. Thank you!

That was a good way to verify that you had fuel to the carburetor using the pressure created by the fuel priming bulb. You did miss out on mentioning the other main culprit of fuel starvation being a faulty fuel pump. I am having an issue with my kicker and I already eliminated my fuel line as a culprit by removing my connection to my main tank and connecting to a known working portable tank. Today I am going to connect a “T” fitting into my fuel line after my pump and check the amount of fuel pressure as well as the consistency of that pressure.

2000 model 40 hp Johnson outboard. New fuel tank, line and primer bulb. Engine recently gone through (maybe), it runs good, but will Sometimes not run unless you constantly squeeze the primer bulb, other times it'll run fine. Don't want to just start throwing parts at it....found your channel, you seem to be well versed on the operation of outboards. Hoping you or a subscriber can guide me to the proper troubleshooting needed to get the engine running properly. thanks in advance.

Thank you! Very helpful to remove the mystery of an outboard motor!

We rented a small fishing boat on a lake in the Sierra Nevada mountains. It would run for a while then quit. We looked around and saw a lot of other boat renters waving for a tow. I found that priming a few squeezes would get it started but this time when it started to stumble I'd give the bulb a few squeezes kept it going. Annoying but better than rowing! Interesting that every boat they rented had the same problem huh?

Wow! Great video. Quick and clear instruction. I needed this last spring.

Great tips. Having trouble with fuel getting to carb. Very helpful thank you.
