Was doing 55 mph today and all of sudden loss of power. Acts as if its not getting gas. I did manage to get her home by pumping the throttle. After bike cooled off, i did restart and the same thing. Wont hardly idle. Have to keep pumping throttle to keep her idling. Thing I did notice is, when I turn switch and hear fuel pump, it sounds different. Sounds as if its blowing the gas in the tank. Yes I do have gas in it. Probably had at least 2 gallons in it when this started. I did add 2 gallons just to see if it would make an y difference. It did not make any difference.

 

What aftermarket stuff do you have on it? Fuel tuner etc. More detail. If you run engine and it shuts off, open fuel cap and see if any suction is there. Is EFI lite on?

 

It can be many issues, but the first thing, I would do is to check the fuel filter and fuel line, to see whether there is s good flow.
Just a thought!

Sounds as though the fuel line from the pump to the quick disconnect may have came loose or has a hole in it. At 25k, I replaced the filter and hose; and definitely remember the hose being longer and of better quality.

Remove the gas cap, turn on the ign/run switch and listen to inside of tank. If as you say, it "sounds" as though the fuel is blowing in the tank, then there's a supply line problem. Or have someone do a quick pressure test and this would also shed some light.

Good luck!

 

I have a Power Commander 3. I just took it off and nothing changed.

My check engine light is not on.

 

My 07 FLHT had leaking fuel lines in the tank. Check with dealer, the fix may be warranted, mine was.

 

Fill the tank up. If the problem goes away it is the fuel line in the tank.

 

I'm betting you have a leak in the line in your tank. A buddy of mine had the same problem and thats what it was. Change your filter while your in there.

 

I found my problem. The o-ring blew out in the fuel pressure regulator. The reason the o-ring blew was because one of the tabs that holds the regulator in place broke. Have no ideal how that happened. What was really amazing was how cheap the regulator body was. Seventeen dollars at the HD shop. I figured it would be at least fifty.

I had planned on replacing my fuel lines while I had it all out, but nobody had any submersible fuel line in stock. I checked my lines out and they looked ok.
