Hello everybody 'Lurgs' here welcome to my channel and today how to replace the petrol fuel hose on
your Mountfield petrol lawn mower right let's get cracking, this is a Mountfield RS100 SP414
but as long as you get the right petrol fuel hose for your Mountfield petrol lawnmower it should be
the same for most other models if you've still got some petrol in the tank my advice would be just to
run it until it's empty or when you take the fuel pipe off just drain it into a suitable container,
what happened with this one is I went to mow the lawn and it wouldn't start so I checked the petrol
in the petrol tank and it was completely empty and the whole shed where it was stored stunk of petrol
and it had been leaking all over the place what happened was the fuel hose deteriorated
and it actually got a split in it and it was just leaking all over the place and I ordered
a new fuel hose for this petrol lawnmower and with the magic of video editing it's already arrived,
make sure that you order the exact right fuel hose pipe for your Mountfield lawn mower because they
will vary in width and length this particular one has got a larger diameter at one end so it's best
not to just buy a standard fuel pipe and just try and adapt it just get the exact part number
that you need today it's a nice warm sunny day so I'm just going to leave this fuel pipe in the sun
just to warm it up a bit and that will just make it a bit more flexible when I'm doing the fitting,
tea oh. The first thing we need to do is get the old fuel pipe off now you can see where this one
has actually been cut and split what you've got is you've got this metal clip just squeeze that
and that makes it wider and then just slide it off now obviously it'll be much easier with two hands
just slide that clip that just keeps it nice and tight
you can see where it's really deteriorated there and as I'm pulling it out that is the
orange fuel filter you can buy a replacement one of those if that's got lots of dirt in
it or you can just give that a good clean with some petrol you can see how bad this pipe was
no wonder it leaked all over the place it's really poor I don't know how old that is.
This is the fuel filter this one is not too bad I'm just going to slide that back in
I'm just going to put the metal clip back over there just so I don't lose it
whilst I'm doing that there's a link above now about how to defrost your freezer easily in
under 15 minutes, now we just need to remove this whole pipe now this goes behind the back of the
carburettor for easier access to get this off we need to take this cover off so this just unclips
this is the air filter which is easily replaceable but this one is actually not too bad condition
if you want to keep that and give it a good clean there's various different ways of doing that
to remove this cover you just need to undo these nuts here and these are 10 millimetre nuts
just take a socket and undo those anti-clockwise
Whilst I'm doing that there's a link above now about how to fix
sticking curtains on your curtain rails that is a really top tip!
And put those somewhere safe so you don't lose them now the petrol pipe hose
goes around the back here into the carburettor and again that's got a metal clip on it
so we just pull this cover off now be very careful when you're pulling this off because you've got
these two metal sheaths surrounding those bolts make sure you don't drop those on the floor
just be aware of those don't pull it all the way off because it is still attached
to the carburettor via the air pump you're basically just moving it out of
the way just to give you better access to the fuel pipe into the carburettor
if we just zoom in here you can see where this other metal sheath cover
is make sure you don't lose that
what we're going to do now is remove this old deteriorating fuel pipe it's got a small
attachment on a bracket which pops into this hole if you just squeeze that and push it out
that just holds the fuel pipe in place now just squeeze this metal clip and slide it off
again this is much easier with two hands
now you should just be able to slide the fuel pipe off
if you're having a bit of difficulty it's time to pull out the big guns,
your pliers! Get a fairly decent grip on this and just pull it off you don't want to squeeze it too
tight because you've got a brass nipple which goes into the carburettor you don't want to damage that
whilst I'm doing that there's a link above now
about how to check your car battery using a Multimeter
Great stuff that old fuel pipe is now off make a note of where the fuel pipe goes
because when you put the new one back in you do not want to put it in a different position
if your petrol lawnmower is slightly different to this one it's definitely worth filming where
the old one is so you can look back on that when you're installing the new one
and that is the dirty old pipe that dirty hose
again I'm just going to put the metal clip back on there so I don't lose it
take that bracket off because you're going to need that for the new fuel pipe
I'm going to put it on the new fuel pipe now
and we're ready to fit this on this has been sitting in the sun so it's nice and warm
just makes it a little bit more flexible I would not recommend putting it in warm
water because you don't want water mixing with petrol that will be bad news I'm gonna put the
metal clip over the fatter end and it and the fatter end goes at the fuel tank end
that's really important so it's got a slightly larger brass nipple on it make
sure you thread it through in exactly the same place where the old one came out from
and then the fatter end you just need to line it up push it over the top and just
gradually squeeze it gently twisting it left to right and sliding it on
once you've slid it all the way as far as it'll go like this you can then put the metal clip on
give that a squeeze and then slide it backwards
as soon as you let go of it that puts a tight grip on the fuel hose
now we're just going to put this clip into that hole that just holds it in place
and now we're ready to put the other end into the carburettor
put the metal clip over the fuel hose
give it a squeeze
again just slide it on twisting it left and right gently just push it all the way home
once it's all the way home as far as it'll go
then slide that metal clip on
give it a squeeze
and then when you let go that gives it a nice tight grip
fantastic
so this is now installed obviously we've still got no petrol in it at the moment
I'm just going to put this cover back on again mind those metal sheaths
make sure you don't drop those
it just slides onto those two metal bolts just line it up and slide it inwards
it should go in very easily don't try and force it
once those bolts are protruding through you can start putting your nuts on
I always hand tighten first because you don't want to damage the threads
once you've hand tightened it a tiny bit you can then get your socket on there
and tighten it up fully, whilst I'm doing that there's a link
above now about how to clean your uPVC guttering so it stays clean
just going to tighten it up securely now
again don't go mad with this doesn't have to be super super tight
just tight enough that it's not going to fall off make sure you haven't kinked any
of the hoses at the back you've got this air hose which is where you pump air into the carburettor
then put the side cover on this just clips in
this clip can be a bit temperamental so make sure you push it home nice and tight
as you can see from the fuel tank it is completely empty so what I'm going to
do now is just put some unleaded petrol in here I'm not going to fill it all the way to the top
just in case we've still got a leak but we shouldn't have so I'm just going to put a tiny bit
of petrol in here obviously be very very careful when handling petrol it is extremely flammable
if you've got a petrol canister with a hose on it that is obviously safer
that's enough for now wipe up any excess petrol with a rag
then put the fuel cap on obviously now we've got some petrol in there
so before we start out we're just going to check the hose make sure you've got no leaks
and this one is looking great there's no leaks on this
but it's time to fire up the beast pump three times
oh yes just going to quickly run it up and down this garden come back and then check
the fuel hose again make sure you've got no leaks there shouldn't be any leaks at all
it's just worth double checking before you fill it all the way up again with petrol, whilst I'm
doing that there's a link above now that had to keep your washing machine hygienically fresh
and
what a lovely day it is
it's good it's running smoothly just gonna switch it off just one more final check for
any leaks on the new fuel pipe and this is looking absolutely fantastic, and I hope that helped you
