When I hover over the URL in Coffee's post, it displays the truncated version, which is obviously not gonna work.

appears in this Ducati forum that their stock pump has these specs (direct quote below)- they are dicussing the pump from a Ducati 999 which was referanced to fit the pump you found at CAcycleworks. Bit more flow but still the same pressure. Should be good- Nice if it "fits" like the stock one- can't go wrong there

--------------------------------------------------------------------------------

Ducati fuel pump specification: flow rate 120 litres/hr (32 gal/hr.) Outlet pressure is regulated to 3 bar (44 psi.)

People have used a Ford GT Mustang pump.

Walbro makes the fuel pumps for many Ducati 4-valvers. Get the part number on the pump - either 5CA305-2 (white box) or 5CA305-3.
V. E. Peterson in Ohio (800-537-6212) will sell you an exact replacement pump for under $90. Ducati wants about $240.

It's also been posted that the Bosch part number on the pump that came out of a Corsa tank matched grey market Fiats and a Lancia Thema from '89-'92.

Make sure the Ducati pump is actually bad (not the fuse or relay) by applying 12V directly.

Thanks for finding that other info, I was gonna wait until I had confirmed that it's a 30mm pump body, and thus, able to fit into our holster/flange plate. Also, I was hoping that someone with a bonafide =bad pump would be willing to get one and hook it up before we pronounced success. I rode my bike today 60 miles, got 40mpg, and my bike NEVER DIED so I am hoping my cleaning job worked and I will doing a monthly clean with a 1/2 pint or less of injector cleaner, which means I won't be hooking up the gold Ducati pump anytime soon, but carrying it as a spare.

Thanks to everyone!

So I am guessing that since there IS pressure relief (the hole) then it is NOT necessary for the pump to know what system it is running in, it just pumps......I see what you are saying now, I hope Manic is reading this....


The pump seems to respond to pressure in the system as evidencied by the fact that it shuts off after pressurizing when the key is first turned on. My guess is that there is a small accumulator somewhere in the system, and the pump cycles on/off to maintain pressure between a pre-determined high & low. If that's the case, then the actual flow of the pump is not going to be real critical. The power-on/power-off duty cycle may be another story, but considering the in-field failure rate of these pumps, duty cycle may be a problem with the stock unit.

I'm just going to order one of the eBay pumps and keep it as a spare.

Typically, the pump is run for 2 seconds when the key is turned to the run position by a relay to pressurize the system. Once the external control sees an RPM signal, it will energize the relay to power the pump and the pump will run continuously until the engine stops. It is not respnding to system pressure, that's why these systems have pressure regulators. I am not saying these pumps will not work. I'm only saying that the 92 Civic pump pressure relief valve is not meant to regulate pressure, it is there as a failsafe. If you look at the specs I supplied, you can see that the relief pressure is substantially higher than the required regulated pressure. I think it would be foolish to just try one of these pumps without an in depth knowledge of the Husky fuel injection design and the pump's design you're installing as a replacement. If you trully know what your working with and can make an educated decision as to whether a particular pump will work, than I say go for it. If you're guessing based on just fuel pump pressures and flow rate than you are plain & simple, rolling the dice. If your willing to gamble, I again say, go for it! I sincerley hope it works. I'm just not that brave.

 

[Manic]

I will do some reserch and see if I can get you a more defined description of how the returnless system works on the newer model Hondas. My guess is that the Huskys use a similar system, but again, at this point I don't know enough about their system & don't want to supply the wrong info.

P.S.
Pick up my 11 TE310 tomorrow night!!!

Great news! Glad to hear you got it going without spending $600. I'm thinking I need to add a fuel pump cleaning to my winter maintenance list .......

 

[OlderHuskyRider]

P.S. Pick up my 11 TE310 tomorrow night!!!

Whoo-hoo, good luck on the pickup, hope the bike is all good and ready for ya.

Manic, thanks for your help and knowledge on this problem. I think I've gotten off the Civic fuel pump as a possibility since we found the gold CaCycleworks Ducati pump, that I hope to have in my hands this week and verify whether or not its 30mm in diameter and would thus fit in our holster with no trimming, crossing my fingers....

OHR, glad you're able to get the bike out of the garage and into its natural habitat! I appreciate all the info you've shared here from steps you've used to troubleshoot to parts sourcing. If the Ducati pump ends up being a go, you've saved future failed pump owners (and yourself) a lot of dough. Have fun!

Thanks for the props, man, I've got over 20 hours into this project now, with some solid results and more to come. Here is a post from a guy in the EFI/Carbs sub-forum. In the post, when you see "X36", that's supposed to be "XJ6". If his piece about it being in a Husky 510 for 6 months is true, then this would be a pump I would buy and install at the drop of a hat. We need a tester for this pump from CH here, won't be me, I am the tester for the gold Ducati pump, I ordered one for $150 and it will be here soon.

I was faced with this fuel pump issue also.The replacement pump I used was for a 95 Jaguar X36 #951-0008 It is bigger and you have to trim the support bracket.Actually I feel a slightly larger pump will help service life. It's been in my customer's 08-510 for about 6 months with no issues.I can sell you one of these pumps if you need one.

The 951-0008 part number he mentions is Denso. Below are all the other makers of this fuel pump. I've ridden and visited with 5 different auto stores here in Austin, none had it in stock, NAPA was the best price at $134 and could get it in 4 days. I looked at pics of this pump on their computer screens, it IS the one found below, and this pump IS configured correctly at the bottom, with a centering peg, with the uptake tube off-center, 2 electric leads up top with the out-flow tube. I could not take any measurements, but I am assuming its a 35mm diameter because the auto poster guy said the holster/carrier had to be trimmed.

1995 Jaguar XJ6
target price $134 - some of these are $170-$207
Walbro GCA338
AC Delco EP490
AirTex E8285M
Delphi 25337934
Delphi FE0200 - in Austin TX, NAPA can order this one for $134
Federal Mogul/Carter P72252
Denso 9510008
GM 25313959
Hella H75014421
Jaguar JLM12159
Jaguar JLM12204

This pump MAY be available at fuelpumps.com for $126.95

I got my Ducati fuel pump in today, ordered it Monday, USPS, $5 shipping on a $149 pump, awesome.

BAD NEWS: it's a 38mm pump (our pump is 30mm), the carrier/holster on a stock Husky will need to be trimmed/removed for fitment, much like the Denso pump that member "auto" put on a 510 http://www.cafehusky.com/forums/showthread.php?t=3573&page=2
and Cristian's Romanian pump http://www.cafehusky.com/forums/showthread.php?t=14131

GOOD NEWS: The bottom of this gold Duc pump is correct: centering peg in the middle, take-up hole offset,
On top: 2 tab electrical and outflow tube.
AND it was designed and manufactured for use on multiple models and sizes of FI MOTORCYCLES.!

BOTTOM LINE: I will not hesitate to use this pump with my TE 450. I will have to study the mounting aspect due to the pounding that my bike will be taking off-road, I don't want any slippage.

 

[Mr Sleazy]

Hey OHR -

Do you have any photos of how you mounted the Duc pump to the Husq plate?

Thanks!

 

[auto]

Well at least you have a pump for a lot less than $600.You'll find out you have to trim the entire support away.You can make some type of a support shaft or SS safty wire the pump across the top to the base.Like I said, I feel the larger pump means longer service life.All the parts are a bit beefer.Now BMW,Oh I mean Husky can stick that $600 price tag up their?

I might not be installing the Duc pump right away, I've been sitting on the following little nugget for a couple of days now.....my dealer emailed me and said that Husky would warrant my fuel pump alone, which I am assuming that they are gonna ship him JUST the fuel pump and NOT the entire assembly. If I can get him to admit this, then we all have the ammunition to say to Husky, "Hey, if you have the 30mm pump that fits in our flange plate holster, MAKE IT AVAILABLE TO US.

I am waiting for a call to say that my part has come in and then I'll see how much info I can get out of them about what is gonna be replaced. I'll report back.

 

[waserman]

That is awesome,now if they only give up a part number.All will be honkey dorey in the land of OZ,or Huskey.

 

[firebolter]

I have researched alot of other OEM pump assemblies and almost all of them, have the pump alone as a part number so that you can just buy the pump. most are around 100-150 bucks. Seems Husky could ease an issue and make FI dirt bikes more acceptable to the fuel pump haters out there if they would address this and make just the pump available. Could be a great marketing move.........

I bet the send the whole assembly- IF they send anything at all. Nice that your dealer followed through.

 

[Manic]

Thanks OHD for all your hard work & reserch! Sounds like, as others have said, we're making progress!

 

[firebolter]

I went and downloaded the Sherco parts list for their 250/300 EFI enduro bikes from their website. Then I looked at Gas Gas EFI bikes and part lists. Interesting!

Sherco list 2 things for the fuel pump in their EFI bikes

Now one is just a pump and the other is a mount Assembly according to the fiche, so it appears you can buy just the pump or part number 0402. So I call and that part is 450.00!

When I go to Go Fasters (Gas Gas Importer and parts place) look at the Gas gas Enduro EFI bikes fiche, they list their fuel pump as Model: MFS400180100 for $552.81, so like Husky, you gotta buy the whole unit.

My point is, this is not just limited to Huskies apparently..........I think the work that OHR has done to amass his list is the closest options to "affordable" alternatives we will find as other bikes OEM stuff appears to be bundled as well.

I am not saying these fuel pumps from Gas Gas or Sherco would necessarily work, just wanted to see how they list/carry theirs since they are similar application (dirtbike).

 

[HUSKYnXJnWI]

If my pump died tomorrow I'd get the ducati pump- then assess mounting- if its a simple trim of the plastic- so be it. Otherwise I'd fabricate an aluminum carrier.

gotta say- if company did offer the pump separate from the assembly-I would have expected gasgas to...
