P**sing Petrol..

Can't get the search bit to work so sorry if this is an old question.

Could smell fuel very strongly when starting the Griff yesterday so had a look in engine bay...

Bloody hose had split before fuel rail and was peeing fuel straight onto HOT manifold...
Managed to trim hose back and used new hose clip but rubber looks like it has had serious heat degradation.

Well worth checking folks and a definite replace next service or sooner.

Can I get this hose from Halfwits...?
Where does the hose connect back along the chassis..?
Or.. what sort of length am I looking at..?

Hoping to get it on a ramp this week and pull the new thro on the old as it looks a right pig to get to.

Cheers.

Very common problem and everybody with a Griff reading this should go and check their hoses for cracks inside the bend right now.

The job is not as bad as it first appears. I found it best to lift off the Plenum, then you can see and get at where both pipes join with the solid feed and return. They are not as long as you would think when looking from the top. Be certain to get the correct grade fuel line not just “pipe” and use fuel pipe clips rather than normal hose clips. You will need some gasket compound for the Plenum. Got my bits from the local fuel injection place so don’t know about Halfords.

Whole job should take no more than an hour.

Mine split in exactly the same place. I didn't remove the plenum but if it makes it easier (certainly took me more than an hour) then that's worth it. There's two fuel pipes so worth replacing both whilst you're at it, the second one on mine split a year after the first. For replacement tube I can defo recommend the marine stuff as it's far stronger and thicker, whatever you get make sure it's lead free variety. I also cut the pipe slightly longer to reduce the tight curve where the pipe bends.

Good luck.

Had the same experience on my Cerby. I first noticed it driving fast around a corner .. petrol had been sprayed on the front wheels so didn't help handling! I stopped and there the whole engine was being sprayed with fuel. Not good and your right well worth checking the hoses regularly or just getting them replaced

Nice one, cheers Joolz & Johnny.

Joolz do you have a part no. for the marine pipe as this sounds favourable..

Thanks.

All I can give you is what's written on the tube itself

Carbopump, DIN 73379 ISO R 1307 10 BAR

Not sure if that helps tho.

Super... Thankyou Sir...

Someone just posted on Chim forum with a fire. dont know cause, but this is an absolute must if the hoses even look slightly perrished!

[Gsw500]

Well the pipe is dual layer and I'm not joking when I say the outside came away easier than peeling a banana.
Only looks like very small cracks on outside tho... very worrying.

Obviously not only a prob on the Griff as we have one Cerb and now an engine fire on a chim (not proven) yet tho..

Hi, I've had similar fuel pipe issues, replaced the 2 fuel lines in the engine bay with braided hp fuel hose used on boat diesel systems. Buy yourself proper fuel clips as well!!!!! After removing the old cracked hoses decided to spend 50 euro on a special hose plier and a 40 cm long flexi 7 mm driver to make it a 5 min simple job. Rgds Bas
