Hi all can any one tell me is it ok to fit jubilee clips on a high pressure efi fuel return pipe to the fuel tank,TAZ
You must flare the ends http://www.youtube.com/watch?v=omlIXsk-Y4k or solder olives on the ends of the hard pipe
Isn't the return line low pressure ?
In which case jubilee clips will be fine.
Return pipe is open to atmosphere, but still flare the ends- belt and braces!
...but don't use Jubilee (worm drive) clips on fuel lines (or any small diameter hose). The screw section is fixed radius and causes 2 pinch points that leak. It's an easy way to fail IVA. You want fuel pipe clips like THESE
Use the correct clips of right sized but as long as you are not using silicone hose you don't need any kind of flare or barb on a low pressure
hose.
Millions of cars with SU and Stromberg carbs didn't have any kind of barbs on the fuel pipe connections and never had any problems.
Silicone hose tends to slip off because it has a lower coefficient of friction, old fashioned rubber style hose tend to stick to the stub pipe.
Just a quick reality check question...
Is everyone really using flared or olive connections on their standard rubber EFI fuel hose connections (say from tank stub to hose or from hose to
metal fuel line)? I just push fitted mine (very tight fit) and then clamped with the correct clamps. I changed a couple the other day as I was
rerouting the fuel lines and, even after removing the clips, the only way that I could get the hose off the stubs was to cut it off.
How much force can you exert with a good tug (oo err missus) compared to the internal pressure when the fuel pump is running?
Well that started some thing thanks for all your advise .taz
