Africa Twin Fuel Pump
Greetings
Have just got back from a 3 month trip around
Europe, had the fuel pump go on my africa twin on way out of Spain.

Fuel was pouring out of the pump, got the bike to a dealer (honda) who said he had never had any problems with one before.

On return saw the fault is fairly common, and yes my bike's engine number is one on list..

Have written to Honda but as yet no reply.
Keep you posted


Keep rollin

David

'Update' recieved letter from Honda who say not our problem, as the bikes not in warranty. So they don't think there is a problem!

My(2000 UK model)Africa twin ground to a halt last night in the pouring rain. I checked the fuel line from the tank and got a sleeve full of petrol so went onto to check for a spark. It had a lovely fat spark so I was just about to call the breakdown when I remembered the current debate on fuel pumps. After 5 minutes fighting to remove the hoses I by-passed the pump and plumbed the tank straight into the carb. Sure enough it fired up and I rode it home. This morning I took it to the dealer who sold it to me and they worked out all on their own that the fuel pump was defunct. Now I'm waiting for a reply from the honda warranty department who six months ago wrote me a letter stating that there was no problem with my batch of fuel pumps. I'll let you know what happens

Re my failed fuel pump. Honda agreed the warranty claim despite 39,000 miles and no service history (service it myself),so it makes you wonder about their previous denial to me that there was no problem. picked the pump up this morning and convinced the shop to let me fit it myself (20 minutes unless you have to wait a week to book it into a busy workshop). The pump supplied is an upgrade on the old one and the part number was 16710 MAY 305 which matches the dutch blokes numbers elsewhere on this page. As he stated the inlet and outlet are reversed which is an easy way to tell them apart if you don't know which type is on a bike you are buying (upgraded pump inlet on right hand side when sitting on bike)

I went to eastern Iran from france last september. Thanks to this web site I was aware of the fuel pump problem, so I took a second hand pump...very very good idea, because my fuel pump breaks down only 2 weeks after my departure in eastern Turkey!

Hi guys,

Strange isn't it? Honda says there is nothing wrong with the pump but they made a modified one annyway...

Honda NL told me also to change the pumprelais because that is probably the reason why there is 'nothing wrong with the pump'. partno 36100-MN4-008, 64 Euro.

But one thing to add to all this: i have the modified pump (16710-MAY-305) on my bike for a while now, and it is also starting to make the same strange noises as the two pumps that died on me!....

When this one dies on me, i'll put in the vacuum pump of AfricaQueens!

Our fuel pump went on our africa twin north of alice springs, right were the two backpackers were attacked, no wonder no passing vehicles stopped to help.
We bypassed the pump with a piece of fuel line to get to the next town were i fitted a low psi pump (2-4psi) off a car to get us over to the east Honda Australia worked miricles to get me a new pump from Japan within two weeks. We had no indication it was going to go.
So carry some spare fuel line.

My fuel pump went at about 20k miles... I'd be riding along with plenty of fuel and the engine would cough as if I'd none. I'd stop, restart the engine and she'd be ok for another ten miles or so before spluttering to another halt.

So having looked at this site and others (check out www.atic.org) I figured it was the pump and by-passed it.

I got the Mikunu vacuum pump from African Queens. It works, was very easy to fit and was about half the price of the Honda part. It's interesting how surprised Honda were that my pump had failed when it's so well documented elsewhere!

I posted the following message on the HUBB in sept. 2000:

Important Message to all Africa Twin owners:
Production Fault in FUEL PUMP.

If the last 6 digits on your frame serial number are 411978 or LOWER -then your bike may have been fitted with a faulty fuel pump.

If your last six digits are HIGHER then you should be OK as the AT was fitted with a re-designed pump.

This information was provided off the record by a technical supervisor at Honda, Norway.

Hi all,

had same problem (with 22.000km)in Brasilia (Vacaria.)I was luckily only 30 km away from a Honda garage, where they took out a pump from a Shadow and installed it in AT. This one is still working for 11.000km.
I paid happily the 180 US and went on riding.

Saludos
Frank

My 99 Model XRV750 RD07 Africa Twin's fuel pump gave-up and replaced it with the fuel pump for Honda CBR900RR Fireblade which is similar to Atwin. No problem now as the Atwin keeps on eating miles.

Just to let you know that the fuel pump I fitted at 39,000 miles after the first one went Tonto is still ok at 66,000 miles(see earlier post). Maybe the modified pump is up to the job, however just in case I have put the mockers on my pump can anyone tell me how much in sterling the vacuum pumps from Africa Queens are and does anyone have first hand knowledge of how they perform?

Further info on the replacement fuel pump for my AT. 85,000 miles up now and it's still going, but I have a Mikuni vacuum pump standing by just in case.

Fingers crossed

Hi Guy's,

Well after I placed the "modified" pump in holland and payed for it :-( it lasted exactly 51.000 km. The contact's on the pumpt were completely gone and I thought it was a miracle it got that far.
I was happy it did not happen in the dessert... would have been a long and hot walk :-(

Now I mountyed a Mogheul Carter centrifugal pump. It cost 160 australian dollar and almost fit's. It's a bit to thin., so a piece of (cut open) water-pipe and that's it.

Switched it on the ignition switch, so it only run's when the ignition is actually on (you can't use the old pump relay!!!)

Good thing: It pumps even if the bike is not turning over yet... so alway a quick start.

Maarten

Pump Update:-

Bike started having the occasional stutter at motorway speeds, very brief so that you convince yourself it was just imagined. Then I put my finger on the black plastic relay end of the fuel pump when it was ticking over and could easily feel the pump going very slowly. Next time I tried it was tapping about four times as fast at the same revs. Decided to put the vaccum pump on in its place for peace of mind.

Score so far
Pump 1 (old type): 0-42,000 miles
Pump 2 (New improved type): 42,000-93,000 miles
