I need to change my fuel filter, rubber pipework and clean my fuel pump to guarantee max performance. These items are inside the petrol tank. Has anybody tried to do this? Do you need fingers like knitting needles or should I leave this to an expert?

Just been reading about RED LINE S1-2 fuel system cleaner. There is a YOU Tube on its effect. This could save me a lot of bother. What do you think?

I changed the filter in mine at the start of the year, it's not too difficult Richard. It's best done with the tank near empty. Undo all the screws retaining the filler cap and remove it along with the rubber gasket, this will give you reasonable access. You should now be able to undo the clips on the rubber hoses to the filter and with a bit of manipulating withdraw the filter. Getting it back together with the new filter is more or less the reverse process and don't forget to refit the filler drain hose which is inside the tank and attaches to the bottom of the filler assembly.

Good luck.

G'day Richard.

I did the remove the fuel pump thing not that long back. It was a learn while doing it thing, so I made the odd mistake here and there. I only had a about 2 or 3 litres of fuel in the tank. From memory:

Disconnect the battery.
Remove the Fuel cap and Surround.
Disconnect the breather that connects to the Surround. (I gave this breather a blast with air in a can to make sure it wasn't blocked).
Disconnect the short hose that goes from the outlet of the filter to the metal pipe it connects to.

Memory not good here, but there is another breather to disconnect, or it might be the hose to the De-gassor?

Unclip the the connections to the pump where they go out of the tank. They were spade connectors on my 907, so should just slip off. The other option is to undo the nuts on top of the pump, but be aware the chance of dropping the nuts and washers in the tank!
The pump is held in its bracket by clips. A twist to the left (or right) unclips it.
The whole lot (pump, filter, hoses etc) should all come out through the hole.

Reverse the process to replace it all.

While I had this all apart, I relocated the filter to outside of the tank, and put a longer piece of hose inside the tank where the filter was. Makes it easier to change in the future, but don't forget there will be two extra places for a hose to pop off and spray fuel on a hot engine and exhaust! I put a piece of HD foam rubber between the filter and a frame tube and a couple of cable ties to hold it all in place.

If the above doesn't make sense, drop another post and I will give it another go. Jog the memory and all that.

Oh, make sure you use fuel hose that can be submerged in fuel. Not all fuel line can.

Cheers.

Nick.
