  2. Fuel filter, just in a metal can. Looks like the ones that come with the rotary fuel pumps.

    It’s the fuel filter as supplied with the rotary pump – the other round metal thing behind the filter. There are plenty of suppliers of fuel filters with 8mm tails. https://www.lsengineers.co.uk/diesel-petrol-inline-filters-metal-type.html

    Incidentally, the worm drive hose clip on the filter is too tight and/or the wrong size and are you going to replace the fuel hose while you’re under the bus?

    Halfords do things like the metal filter.

    I selected mine (i think it was an hff203 ) by sneakily rattling (to find a metal one) and opening boxes on the shelf until I found one I liked the look of...

    I
    Got covered in petrol the other day just trying to take off fuel filter...
    Then though...ah... clamp the pipe which I did. But to change the pipe?
    I have to empty the fuel tank right?
    And what's the 'worm drive hose clip'? Do you mean the ju ilee type clip.

    To change pipe on tank.

    Prepare new hose with hose clamp prepared. Block off other end with either a bolt or preferably a proper pipe clamp tool.

    Gloves, preferably the long agricultural kind for sticking up cows bottoms or plastic bags to keep petrol off skin...
    Eye protection against rust and fuel..


    Loosen screw on clamp on tank. Have new hose ready in hand. Carefully twist old fuel hose until it is free, prepare yourself.
    Slide old pipe off tank spigot. Place new pipe over spigot or use a finger while you fumble for new pipe. Place new pipe over spigot. Do up clamp. If it all goes wrong put the old pipe back on..

    Make sure its not leaking.
    Back off and try to decontaminate.

    If it's the hose to the tank you can do it with fuel in if you're quick! Have the new hose clamped, whip the old one off and quickly get the new one on. Expect to get some fuel on you!

  8. Get a large Meyle clear plastic fuel filter, you need to see if any crud in there which you can't see in a metal one.

    Running it low and lifting the offside should help, both with access and reducing fuel loss.

    It’s the hose clip upstream of the filter – the only worm drive clip in your pic and it may or may not be a Jubilee. You can see how it is crushing the hose, it’s either too tight, the wrong size or the hose is too big.

    It looks like that filter has never been changed, it will be 8mm (5/16”) and the hose should be 7,5mm so it stretches slightly. You should replace the link hose between the filter and the pump also.

    If the hose is the correct size for whatever you're joining together the clip just needs to be nipped up; it shouldn’t leak even without a clip.

    Best to lift the side where the outlet is....it also gives you more chance of escape any leakage.

    If you take the rear wheel of once it's lifted, you can reach in from the arch to change the hose, rather than laying underneath waiting to get a face full. No need to empty the tank, you will only lose a splash.

    A drill bit shank is quite useful to temporarily plug a fuel line. Handily available in 0.5mm diameters...
     
  17. If you’ve a clean tank, a metal one is fine, just replace it during services as you would on a modern car/van.

    You shouldn’t have to be constantly checking the filter.

    Hi just to check.

    The 'in' pipe connects to....?

    I'm thinking the fuel tank as the petrol comes 'in' from there.

    Is that correct?[​IMG][​IMG]
