Title: 701 Fuel Pump?
Post by: BiG DoM on October 28, 2018, 11:56:03 am
Is there any consensus on this issue? Should one replace as a precaution or just fit the Guglatech kit. If the latter should one do all three filters (filler, pump bag, and remove pump screen and fit external filter?

Let me go first.  Personally I have not replaced the pump.  I have removed the small in tank filter after the pump but left the screen in place.  Installed a large external filter.

There is merit in the Guglatech (if it truly works as advertised).

I change the in tank filter every 5000 km's. I run guglatech filters, and a aerospace (10 micron) filter before the injector.

Did you consider the Guglatech Tea Bag pump filter? Anyone here fitted one? What aerospace filter did you fit, from where? I know the Golan filters are good but costly.

Hey Dom,

Didn't actually know there was a filter for the pump (bar the STD one).

Yes, its the Golan. Imported from Rally Raid. Like you say, expensive, but better than being stuck.

Ok got a quick reply from Riaan at Guglatech SA after enquiring this morning about a full kit fix:

"The 701 doesn't have a Teabag it has a mesh strainer and an in-line stupid mini filter, we have all the parts to do the modification.
 
MRT093
MRT099
M27106
 
Remember, without the neck filtering any kind of modification will be useless.
 
701 and KTM  690 after 2010 share the same fuel system platform.
 
I have received the 701 stock on Friday I will send you a quote shortly.
 
Regards

My hunch (reinforced by having seen quite a few RR's in remote places) is that water in the tank mainly stuffs up our pumps.
Jerrycan-filling, or worse, coke-bottle fuelstops we all know, and we'd not think twice when we had carburettors... but with EFI these days things ain't that simple anymore.
The std filtering is probably good enough when you live in Europe, strictly controlled enviro-tankstations galore, but here it's a tad different.
Zero personal experience yet but the Guglatech socks seem to be the ticket: they stop water getting into the tank plus they filter out very small fines.
I presume you'll have to take them out to clean from time to time but that's a minor hassle, anyone obviously will prefer doing this than swapping a fuelpump somewhere out in the field.
With the 701 (and I reckon the 690 also) one has to hold the filler nozzle oneself to prevent jamming it in until it rests on the tank's bottom, in doing so possibly damaging the sock - but I'll do that with a smile.

Yes and I always do it myself anyway as otherwise you have petrol everywhere - learned this long ago. Also with BMW's you can drill a small hole in the filler neck as an extra higher breather which allows you to squeeze as much as a half litre more petrol in a tank ... gas jockeys do not understand this.

Where is the best place to buy the in tank filter on the discharge of the pump?

KTM or E2R ... its a little service kit.

One should eliminate this - Guglatech actually makes an elimination kit for something like R750 which is daylight robbery as all it is, is a small brass barbed straight connector and two worm clips. Source one locally or use a small piece of pipe. If one runs an external filter this is unnecessary and what blocks and causes the pump to overheat and fail.

Did a sleep over ride to Oasis a few weeks ago and on the way home and bike died (bottom of Bainskloof pass). Had to trailer it home. Was sure it was blocked fuel filter. Pulled the filter and it was about 50%blocked after 2500km. Fitted new filter and still no go. Checked power to the pump and it was live but pump wasn't working. Took the pump to Eddie2race and they confirmed pump u/s. New pump is R 6100.00. They said I still fell under warrenty so pump will be replaced. I have in the meantime bought a aftermarket pump form fuelpeformance for R3k (complete unit just like oem) and it was at my door in 2 days from Jhb. Fitted and bike is back up and running. The nice thing about fuelpeformance pump is that it has a slightly bigger filter. I'll keep the oem pump as a back-up.
Just want to mention that contamination was NOT the cause of pump failure.

Yeh, but it was not fuel contamination but the pump failing causing filter to block...

The pump has to pump harder to push the fuel through the 50% blocked filter between the pump and the pressure regulator. I believe this is what makes the pumps fail. The filter gets blocked by the carbon graphite particles deposited off the brushes on the fuel pump motor into the fuel.

That's seems to be correct, so fitting a bigger filter will probably allow the pump to last longer but how long will the brushes hold out if they are wearing excessively?

I am not sure that the brushes are wearing excessively - it would be really interesting to disassemble your failed one to verify. I have also heard some speculate that the black is pigment leaching from the tank. All I know is that it is blocking the in-tank filter. I have removed mine from the tank, fitted a hose connector and a serviceable aircraft grade Gulan filter externally. Easy to service and check. I also have Guglatech filler filter so believe I am covered.

This is what my filter looked like at about 3200km when I removed it.

Is it serviceable or do you replace complete filter?

We are stocking it, but it is back-ordered till mid June 2019.
Approximate cost is R293.25.
It is not user-serviceable.
(we also stock the BMW 800 GS/A IN-TANK Mahle fuel filters, for any BMW boys reading this thread!)

Filter off eBay - you just remove the internal filter and clean it. Golan make a whole range of filters - small and larger.

I see Rade sells a different model to that one for the 690/701.
If I use your link and pick the model it says not compatible. You havent had any problems since fitting it?

Just as a matter of interest I took the fuel filter out of my 501. Looked exactly the same as the one in my 701 ... i.e. pitch black inside.

Definitely going to fit a better filter in there and the one you use seems perfect

Just a question, did you fit it between the tank and the quick connector? Is the inline filter still there?

I have fitted after the QD but should not make a big difference (largely because it fitted better in the space and also makes getting the filter out to service easier). It is a bit of a juggle in that space but I did not want it external to the frame but have seen external filters piped that way as well. Some remove the QD inline filter but mine is still in place at present and am keeping an eye on it as well.

BD, with the in tank filter completely removed, will the carbon from the pump bushes be caught by the Golan external filter?

You can't check it on the part fiche by comparing the numbers.  The piping attached to it is completely different but the actual pump itself is interchangeable. (as is the 500/690).

Very simple.

I fitted a GUD E13 inline filter outside the tank, it currently costs R185, inclusive, and is available at ANY spare shop in SA.

I have not removed my in-tank filter, and at 30 000kms all is fine, BUT it is probably wise to remove the in-tank filter [not the pre-pump strainer] and take the fuel line from the tank-pump to the E13.
