Fuel line connections
Hi all. I'm not sure if this has been covered before but I couldn't find it by searching. It may well be too noddy a question... sorry if
that's the case.
I've run my copper fuel lines through my transmission tunnel and now need to connect them to my tank using rubber fuel hose. My question is, is
it sufficient to push the hose over the copper pipe and secure it with a clip? It seems like it would be a bit crappy especially for the high pressure
injection line.
I was wondering whether I need to use connectors similar to my brake lines or is that overkill. If not where is the best place to get them from?
Many thanks

I've flared mine and secured with jubilee clips.
I don't have to worry about SVA, though...

Rich,
What I did was use a brake pipe flaring tool to put a slight compression ring on the ends of my copper pipe. You can buy brake pipe flaring tools
quite cheaply - mine is a £30 or so "Laser" tool and has come in very handy indeed for fuel pipes and brake lines funnily enough!
If you do this then make sure you don't do a full "flare" on the fuel pipe, all you need is a slight amount of compression to bulge
the end enough to provide positive retention in conjunction with a fuel hose clip.
By the way, you should use proper fuel hose clips and not just standard jubilee clips. There is a difference.
Cheers,
Craig.

When using "rubber" fuel hose I assume you mean flexible and fuel resistant hose with appropriate marking's. Otherwise your P &
D will not last very long when burning!

I soldered a copper compression olive* over the end of the tube before fixing the rubber tube.

Thanks for the replies. A flare and a clip it is.

Make sure its a proper fuel line clamp!
Jubilee clips are wank! :-)
It needs to be a proper fuel line clamp - otherwise I'm sure they'll fail it....
I doubled mine up on the connector to the tank...

If you believe you're not crazy, whilst everybody is telling you, you are - then they are definitely wrong!

I'll take my chances... 
Jubilee clips are fine for many purposes and if you get a size which suits your application perfectly then they do a good job. However, petrol pipe
clips are designed to work over a much smaller range and should produce a better seal due to more even clamping pressure. They also use a nut and bolt
rather than the course threaded worm drive type arrangement used in jubilee clips.
Cheers,
Craig.

LOL Craig :-)
Sorry didnt read your post before - otherwise I wouldn't have posted!
I don't care who FLAMES me - but why would FUEL HOSE CLAMPS be invented?
Those who flame me can do so, after they have put the FLAMES out on THEIR backs, after using jubilee clips LOL

I've already some fuel clips I just haven't got the hose yet and didn't want to if a needed a special size for connectors etc.
