Fuel lines and filters advice please

[(RIP) willstatt]

I want to fit an inline fuel filter to keep the camel dung out of my engine when re-fuelling in Morocco. There are two fuel lines (and two breather pipes) that come from the pump unit on the tank (standard 1150 GS)
Are both the fuel pipes feeds? One to each T body perhaps? Or if just one is feed, which one?

Advice please.

Thanks

Will

You have a fuel filter in the tank -

move it to the outside if your going to put crap fuel in your tank - lot easier to change, and you won't lose any fuel if you have to do it by the side of the road .

How would I move it from inside to outside, and are both pipes fuel feeds?

Fuel pipes.....

The two pipes with the QD couplings are for feed and return. The fule injection pump delivers far more fuel than the engine can consume in one gulp, so the system is a recirculatory type as on nearly every fuel injection system.

Perhaps a more user friendly method of filtering the crap from dubious fuel ( its the forecourt pump that you get the fuel out of not the fuel itself that is dirty, even though they have or at least are supposed to have micro mesh screen filter systems in the delivery pumps) is to use a funnel with a filter screen in the kneck. This way you can stop the crap getting into your fuel tank in the first place, as most of these funnel/filters are plastic you will not have any trouble storing it on the bike.

Available at great expense from Demon Tweeks, your local motorists shop, Busters, M and P, or even Hein Gericke.

Hope this is useful, I wouldn't go messing too much with the system on the bike after all Euwen and Charlie did ok.

No and Yes....

Don't move the filter this seems like excessive work...Euwan and Charlie managed 'the long way round' with no extra fuel filtering. Apart from Euwan washing his eyes with fuel.

Try getting hold of a fuel funnel with in-built filter at the base (Halfords/Demon Tweeks etc) they are made of plastic usually and will stow on the bike quite easily. Just pour the fuel into the tank from the petrol station pump through the funnel and that should stop any dirty fuel problems. You can also use coffee filter papers placed on top of the filter guaze...amazing what you find out in the SAS!!!!!Gets sand and the teeniest particles out of the petrol.

Your biggest worry in terms of fuel will be condensation (water) in the fuel. No filter will stop that or prevent it getting into the injectors.

Both of the pipes at the side of the tank (the ones with the QD couplers) are feed and return as the injection system runs on a recirculatory basis. Check or preferably replace those QD couplers before you set off on your trip. Good luck

Worth taking a spare QD fitting but more importantly (& easier to carry), I'd also take a couple of the small o'rings as I've heard but not experienced it myself, that they are prone to perishing.

Will...I'm having my filter moved outside by our very own Steptoe soon, mainly 'cos it's going to make things much easier in the future.....but TBH, Don't worry too much about the fuel in Morrocco...most of the petrol stations are big shiny ones just like over here, and we didn't find any problem with poor fuel.

(didn't hear any moans about fuel from any of the group with us until we got into and below Mauritania actually)
