Fuel Hoses

Good People of uk.rec.motorcycle.classic,
Does anyone out there know of a supplier for fuel hoses. I need a selection
of fuel hoses and breathers of different sizes and my local bike shop is
making worrying noises the availability of genuine items.
Thanks in advance
Vin

 

At Kempton Park (and presumably other autojumbles) there's always a bod
with rolls of fuel hose, plastic hose, breather hose, you name it, in
all sorts of sizes.

I got some fuel pipe, and some pipes for my vacuum gauges[1] last time.

[1] The original ones rotted like feck.

 

motor factors should have hose by the reel and sell it by the metre . Jeez
I'm a one man band and I carry 6, 8 and 10 mm (1/4 5/16 & 3/8)

What effect does unleaded have on the older stuff?

clear braided neoprene type hoses ( most of which has gone a inflexible
dark brown by now). There were stories of fires caused by hoses bursting and
leaking. Modern petrol contains benzene like chemicals , the older stuff
doesnt. Come back five star.

Hmmm. Come to thinking about it, I had major problems with a very short
fuel hose on the Corrado (four wheel thingy for use when the wife has had
her hair done)

Only a 12cm job between a pressure regulator and the fuel rail but the
bugger split putting a deluge of unleaded all over the exhaust manifold. I
just bought a metre or so of 'fuel hose' from Anwars Discount Deals down in
Cleckheaton but it kept going rock hard and cracking again after a day or
two. After many replacements I gave up and got some recommended stuff from
the dealership. Three times the price but different again!

It's LRP that does...

 

There is a big difference in pressure between fuel injected systems
(high pressure) and low pressure carbureted systems. I would *never*
attempt to substitute generic fuel line intended for low pressure use
for a high pressure hose used in a FI system.

It sounds as if you bought some cheap hose as well, that wasn't even
suitable for contact with petrol, doubly bad. For low pressure use on
a bike, I would go for Tygon(tm) hose every time, it is the very supple
grey stuff that is used as original equipment on lots of Jap bikes.

 

mind, if it's sold as petrol pipe, it should be OK for low-pressure use.

there is an issue with high-pressure pipes though, as injection systems can
easily be at about 5 bar.

 

I'd forgot that a short length of the cheap hose that gave me problems had,
in an emergency, been temporality used in a test rig for the second stage of
some scuba gear - somewhere between 6-10 bar. I dug it out yesterday and it
still remains flexible and un-compromised. The other factor with it's
application as a fuel carrier that gave me problems, was probably the
intense heat at that particular position in the engine bay. An offending bit
still rolling around in the bottom of the toolbox box is now totally rigid
and impossible to cut with a knife blade.

That reminds me: I think it's about time I bought some[1].

Any recommendations?



[1] Apparently, we need to fettle a certain CBR600 so it can be sold
before we can start work on Project BoxOfDog[2]
[2] Estimated start date: November 2002[3]
[3] Yes, it's slipped a bit.

 

Eddie fascinated us all by saying...

Morgan Carbtune 2. Very easy to use, and they don't break when you drop
them.

Ah, yes - I remember them from last time I thought about getting some.

Anybody know the cheapest place to get them? I see you can buy them
direct for GBP52 - anybody better that?

 

I dropped by his gaff last month and had a new set away. Quite well made.
The damping has improved, not perfect but better than the dial type and only
really an issue on tickover. His website is his *best* price.
It seems to be a bit of a family concern. Himself, wife and young son all
beavering away in a small unit. IIRC it's been about for decades?

 

yebbut, they don;t use cheapo petrol pipe for those... I assume they use
metal pipes.

OK, call me tight fisted, but...

I bought 10 yards of 1/4" diameter clear plastic tube, and put a
U-shaped groove in a 3ft piece of 3x1, into which the middle of the pipe
fits snugly. It also has a hole to hang it up vertically (crucial, that
bit) Around 50ccs of best 20:50 was carefully trickled in from one side.

One pipe goes to each carb. It's turned out to be very sensitive (read
far too sensitive), and works a treat. Total cost: less than a fiver,
plus a bit of time (you could use cable clips or wire to hold the pipe
if in a rush).

I wish I could claim some sort of originality, but the idea comes from
one of the Airhead sites on the net. It would work for carbs >2 by
balancing a pair, then using one of those as a reference for the rest.
Would take longer than with a 4-dial setup, but cost much less.

BTW, I found I needed around 6ft of "U" when starting off, until I'd got
it settled, then could achieve +/- 3" of oil for most of the rev range.

That was when I thought I'd re-check the valve clearances, and two
Helicoils, two exhaust valves and four valve guides later, the rest is,
ehem, expensive

Still, should be back to re-balancing tomorrow night...

OK, you're tight-fisted.

BTW: couldn't you reduce the sensitivity by using thicker oil?[/QUOTE]

Yes - 20:20 hindsight in my case! I deliberately added a bit of WD40
because I feared it might be too stiff. Spot the twit!

Regards,

Simonm.

 

Davida. IMHO, really are worth the money. No real damping issues,
steady on my v-twin Guzzi, even on a lumpy idle.

What is it with Halfords? I'm not having a go but IMO Halfords is the
motor/computer equipment equivalent of Dixons.

Go to your local motor factor, cheaper, usually better quality, greater
range and the staff tend to be infinitely more knowledgeable.

Try Partco (IIRC, the old Unipart chain) if independents scare you
http://www.partcogroup.co.uk/branch0.htm

 

Halfords is great if you know what you want - decent choice, keen
prices.

If you *don't* know what you want - "I need a widget for undoing the
thingummy and then that magic fluid that cures it", then local motor
accessory shops are the bollocks.

Same aproach and general rule applies to big DIY superstores and
independent ironmongers, IMHO[1].
