Question Fuel pump replacement tips?

So, I pull her out of winter storage a few weeks back, get a few rides in. Go to hop on the other day and I do not hear the familiar whine of the fuel pump.
Per the manual I take a voltage reading on the pump connector, and it has juice for a few seconds during the FI light. I guess this leads me to my question.....if the pump is getting power but not priming, it must be a bad pump, right? Granted it is a 14 yr old bike, I barely have 10k miles -- seems like it shouldn't just fail all of a sudden?

Looking around at pump replacements, I see everything from $40 ones, to "OEM" $200-400. Is the $40 one work just the same?

Also, messing with the fuel systems seems a little past my knowledge level, any tips or step-by-steps out there someone else has done?

as always, thanks for any help!

Pump is bad or the connector is bad. First make sure connectors are good, then go for the pump.

Hope that helps!

I changed my fuel filter instead of the pump, but the step by step process is the same anyway.

Hey thanks! That is what I was looking for and definitely helps. Not sure if I really need to, but I think I will replace the fuel filter too, since I am already in the fuel tank anyways. Your parts links were super handy.

I am hoping the $40 fuel pump I just ordered works as well as the $300 Honda OEM one.

Please let us know how this works out for you...I may be in the same boat soon.

This^ I also had to order a new tank after a few were broke on mine. I fixed when it was just one, and it held for the torque value, but another broke so it was gone. USE a torque wrench and give it the 12 lbs it requires (pretty sure it was 12).

Also, you are going to need a new rubber gasket that the fuel pump flange needs to mate with the tank. There is a very fine lip where the gasket seals, the oblong shape. Be VERY VERY Careful here. If you ding this up, or pinch it or bend it with a wrench or pulling the pump out you will have a hard time getting the gasket to seal and you will be dealing with leaking fuel. Take your time and do it right. Also, do your fuel filter, its a cheap *** part and never a bad idea to know your fuel is clean. Take your time again, and be safe.

The gaskets are impregnated, so resuing the one that was on there may or may not work, but more often than not they do not seal again. Grab a new one. Cheers

Thanks for the comments and help!

So, all my parts came (fuel pump, fuel filter, new gasket, washers, etc). Did the install (in about 4 hours) and.... nothing.
Definitely would appear with these kinds of things, you need to double and triple checks all the components involved. I had to tear it all apart again and upon testing all of the wiring, found that the blue (positive wire) in the tank does not appear to allow more than 0.02-0.04 volts through it -- pretty sure it needs all 12 to get the pump going. Looks to be the wiring connection piece between outside and inside of the tank is loose/defective. Unfortunately, it is all sealed up and would be difficult to repair so I am ordering a new pump assembly plate/stay. Super frustrating.

Fingers crossed.

remove rear cowl and on the exhaust side of the bike there is 2 relays, i believe it is the one closest to the taillight, stick a test light to it, if no light you can either jump wire it for a temp fix or replace the relay and i bet itll work, mine did same thing
