They only have 10mm od , 8mm id, any good?

[Alex]

They'll work fine

[Matt Cole]

Yes 8mm I/D is what you want. Some use 10mm for high powered cars.

[Woznaldo]

I'm pretty sure it's 5/16" or 8mm OD, not ID.

Woz,

I would go for 3/8 OD with an internal of 8mm:

How did you get on with swapping your fuel lines. I got to do this next.

[bigdavec1974]

Errrr not done it yet, next Saturday though. I'll keep u posted.

8 mm is the one!

done mine about 8+ years ago.

Practice the bends using a 30mm socket in an engineering vice.

Use the old lines as a pattern.

[bigdavec1974]

Bit of an issue there. The old lines were just replaced with rubber! Haha

[Higgy82]

I was sure it's 8mm OD so will be good to see how you get on.

[bigdavec1974]

What's the best way to join the rubber sections to the copper lines? Do the lines need flaring out at all? If so what's the best way?

Cheers

[Alex]

I just banged on some decent quality fuel hose - I didn't flare mine.

[bigdavec1974]

So pretty much just squeeze the copper line inside the rubber section and seal with a fuel line clip/jubilee clip?

[Alex]

Yep, that's what I've done. Obviously make sure the fuel hose is a good tight fit over the copper line.

[Matt Cole]

Solder a copper olive on and then heat the rubber hose until flexible enough to push over.

[Higgy82]

How did you get on with this mate? Any difficulties?

I plan to do this at the weekend so any tips would be helpful.

Thanks

This is on my list of jobs to do aswell!
