    I suspect a lot of fuel pump issues are actually filter issues, the filter clogs up which makes the pump work much harder. Seems to be a common problem with 800 BM's, mine went at around 50k. As far as I can tell the filter is not changed at any scheduled service and in Oz they are not available from BMW, you have to buy the pump and filter assembly for over $800.

    The reason we drilled the sealed filter-compartments of the fuel pump assembly of the 650s/1000s V-Stroms to bypass the OEM filter altogether, then used an external automotive inline filter.
    Fuel pumps lasted forever after that... and $25 filter replacements.

    Black plastic tank

    Internal filter changed at 45,000km, waisted my time really.
    Original pump still running at 52,000km

    and WR450/250F and WR250/R, plastic tanks and reliable systems.
    All this bullshit about have to filter fuel with socks and fit external filters.

    Manufacturers can build reliable systems when they care

    "wasted"

    That's a decent sized filter.

    Speaking of Petcocks, the old 86 Tenere has an interesting set up with its dual Petcocks on the large tank, a big reserve on one side and nothing on other

    Yeah, a bit strange. The reserve is actually the lower of the two pipes, so it really has two reserve taps - one on each side. I'm guessing it is set up the way it is is because each side of the tank runs well below the central saddle and the right side (unreserved) petcock is purely to allow flow in the crossover pipe. Having two petcocks, each with an off position, then allows you to disconnect the crossover tube (to remove the tank) without losing half a litre of fuel pouring over a hot engine

    There are a couple of instruction posts and YouTube going around as to doing the same on BMW 1200 pumps/filter assemblies which i imagine are similar to the 800 set up. I plan to do likewise with my BMW's.:*sip*

    Quick connect fuel lines. May not be an old idea but they are genius, and allow you to remove your tank without spilling fuel.

    They've been around quite a while on outboard motors - since the '50s at least.
