Re: Aftermarket fuel pump
 
Good to know info. How much was the Husky pump? Our pumps are like $400?

I sucessfully put a $40 car pump meant for a Dodge Caravan in my TL1000 street bike. It worked and the bike ran fine, but who knows if it is was right. It was one of those it fit so I put it in there deals. :twisted:

The criteria, as I understand them, are flow rate (gallons per hour), pressure (PSI) and of course the physical size of the pump (will it fit?). Our bikes have a regulator, so some excess flow "should" not be a problem, other than potentially taxing the electrical system. Our bikes have a pretty good charging system though, with 210 watts on tap. The worry I have with a car pump is that if the flow regulator in the tank can't deal with the increased flow and the pressure put out by the car pump. If that occurs and the pressure reaching the injector is too high, it can richen your mixture. The ECU calls for a certain amount of "on time" for the injector and it does not know there is more pressure behind the injector, so more fuel is sprayed for any given amount of on time for the injector.

The Husky pump looks like an ideal solution compared to a car pump. Since it is meant for a bike, it's flow specs should be appropriate. It is likely better made than our pumps too, and cheaper to boot. I will keep this option firmly in mind if my pump ever acts up.

Do keep us updated on your bike's behavior over time with this pump. This thread should be a sticky :)

Upadate: First the good. I recieved the aftermarket fuel pump, and except for the non barbed outlet hose, it is EXACTLY the same as the stock pump. In fact, the part number on the pump is the same as the part number on the OEM Husa pump. I cannot say whether or not it is a better quality pump than the stocker, my guess is it will be a bit of a crap shoot. Looking at both, I would guess that both are probably a $10.00 part directly out of China. Husaberg should be ashamed of what they get for the OEM one, and I am sure ca-cycle is making good money on them as well. Pump is installed, and working well.

And now, the bad. After installing the pump, the same lean condition exists. I put everything back together and the bike still ran bad. I took everything apart again, and inspected every wire. No faults could be found. With nothing else to check, I swapped out injectors. I have a spare because this is not the first time I have done this rodeo. Swapping injectors made the problem go away, but I am very certain that the actual injector was not the problem. I believe that a bad connection somewhere caused the problem because this same injector was removed last summer when the bike was running lean again. I am thinking that wiggling a wire at or near the injector fixed it.

While the bike was apart, I disconnected, cleaned and inspected every connector, and dabbed in a bit of dielectic grease. I am hopeful that the problem is gone for good, but after having the bike apart a dozen times, I am not optimistic.

Woof. Hang in there, BRN2RDE ... we're pullin' for you.

And make sure that you document *everything* ... with pictures as well .... for your discussion with NA Husaberg.

My ca-cycle pump should be here today. I tore into mine on Friday in preperation for the replacement. Were you able to get all this done wihout those speceal oetiker pliers? Seems to me just using FI hose and clamps will do the job. I noticed the ground connection on the pump was extremely loose on mine. I will make sure it is secured on re-assembly. I am taking pictures and will post them up when I am done. I am also installing the Can Am inline filter at the same time.

No special tools required. Hose clamps work well if you replace that cheapo plastic line with good injector quality fuel hose. Hose clamp do not work well on the plastic line because there is no 'squish room' in the hose. You need to change out the line anyways to fit the non barbed output of the new pump.

I too have a filter installed after the quick connect under the tank. Not the Can-Am one, I found a filter from Napa that is very small and very cheap that was suited for a diesel application so it handles the pressure. It was around $4.00 I believe. It has been on there for several months now and is working as it should.I will post the part number when I get home tonight.

Thanks for the confirmation on what I was thinking. I bought FI grade fuel line and clamps already. I should have mine replaced this week. Hopefully that ends the fuel pump issues I have been having after the tank gets hot.

The other fuel filter part # would be good to have, the Can Am one is pretty large.

Re: Aftermarket fuel pump
 
And the saga continues..... Aaarrrggghhhhh! As previously mentioned I got everything back together, and she ran great. Today I went for a little ride around my place and it ran fantastic. For about 6 miles. Then it outright quit on me. It simply won't fire, like it ran out of gas. The fuel pump still cycles as it should when you bump the start button, but it won't start. I have spark, tested with a screwdriver arcing to a ground.
I can only guess that one of the connectors that I so meticulously cleaned came apart? I will manually add a bit of fuel to the throttle body tommorow to confirm if it is a fuel or spark issue before I take it apart for the millionth time.
I love my Husa, and had probably 3000 trouble free miles on it before this gremlin took over, but I am getting tired of tearing it down. Might be time to consider moving on....

OK, Got it fixed. Again. The non barbed fuel hose connection blew the line off. Looks like the fuel line I got was not the quality it appeared and went a bit soft when the fuel got warm. I replaced that with hopefully better line, and better clamps. So far, so good.

And the inline fuel filter that I added awhile back is a Napa Gold 3027. Very cheap, but has been working very well for 5 months now. If you look at the application for what it fits, you see a couple vermeers with a cummins diesel engine so it is good for a pressurized system.

Whew! At least your new problem was one that made sense and was *somewhat* easy to find.

Keep on truckin', sir!! E-Ticket

Re: Aftermarket fuel pump
 
Thanks for your update. Totally makes sense too - I wonder why they would not put a barb on the fuel pump outlet operating at 50 PSI?

The NAPA fuel filter sounds like a great idea. Good enough for a big rig, good enough for a 'Berg :lol: Just from appearances, the stock filter does not impress me greatly. I have the Can-Am one on mine. Another thing I really like about putting a filter in the line before the injector - it is always there between the dusty outside world and the oh so sensitive injector when you take the tank off.

I may replace the cheap plastic stock hoses in the tank (OEM pump still working fine, knock on wood) with FI rated line and clamps, and safety wire the connectors to the pump while in there.
