you're on the right path here. I was hoping to see the connection inside the solenoid since there is a positive current lead, torn out of my fuel pump. I booked up a $80 'replacement but that wont arrive quick enough. So I'm uncrimping the solenoid body hopefully , tomorrow.
The fuel pump on my 87 vfr700 functions perfectly, but one of the wires have come loose from the inside of the pump. Would you happen to know whether the wire goes somewhere specific or if it just has to make contact with the coil on the inside of the electrical part of the pump? I plan to solder the wire to fix it if I can get inside to see whats what
This bike is not one that you can just gravity feed and cut out the pump. Pickups are raised inside the tank so tank gets down to about 1/2 capacity and will not pick fuel up to run
electric makes a magnet; magnet pulls the points closed(opposite spring load). As the points close 1) diaphragm moves and arm clicks making the electric shut off. Spring returns the diaphragm and electric switch, system repeats. Exact same as horn. Basically the electric magnet pulls it, spring pushes it and they rotate as the mechanical arm flips with each cycle. Once it achieves pressure equal to the magnet; the magnet cant force the movement until pressure drops. Or to increase pressure you need a stronger magnet. On this unit the mechanical circuit breaker is mounted on the button as wings. Button up is open connection at 8:48 button down is closed connection (time 9:02-9:03)
That is a GREAT question! I had to think about that for a minute. Gravity will bring the fuel to the pump…….when it is primed it will pull gas in as it pushes it out to fill the space.
Yes and yes. Since it is gravity feed and closed it will develop suction once running. If air is in the system it could air lock but that doesn't usually occur with this style pump.
I just bought a fuel pump for my Suzukin Intruder....200 bucks!!! But, you know....you get what you pay for....I couldv've gotten a cheap aftermarket but when the stop working you're done....Hell, it's a 32 year old bike ....what should i expect...

8:44?

Hi does It stop the eléctrica motor or the flow Of gas when trae presure is equalized?
Yes, if it is functioning correctly the gas flow will stop when the float bowls are full and the lines are shut off

So, is the fuel gravity fed into the pump or does the pump suck the gas in and push it out to the carb at same time?

Was that a Yamaha? I have a VMAX 1985 and it was not working. A new one would be 160 approximately. I will try to fix it. Thanks for your video.
These are Honda. I don’t think I’ve had any Yamahas yet that are not gravity fed from the tank
I’ve heard bad things about cheap replacement fuel pumps burning out fast. I do like OEM!
Great video. Thanks for sharing!
Thank you for watching! I appreciate the feedback

I believe you made a good decision. You never know what the cheap one will do for ya
Thanks
