Hi all,

I am currently changing all the rubber fuel lines on my car as a couple of them have some cracks and fuel is leaking from somewhere.

I am finding it hard to push the new rubber pipes onto the copper tube.

Any advice. I was thinking hair dryer to heat the rubber. I dont want anything too hot or naked flames. I like my face!!!!

So, any tips?

Cheers,

Biz

a drop of light oil? wd40 or something even? vaseline? something wet and petroleum based. even petrol?

i'm doing fuel lines at the minute too, haven't some across any problems yet though

Olive oil or similar.

Other suitable lubricants are.
Liquid hand soaps (nb hand soaps not detergents ) work quite well.
Castrol-Girling brake grease

Most mineral lubricants (including WD 40 which is mainly kerosene) don't work well on rubber as they just make the rubber sticky.

Use anything suggested above it'll all prob be fine, but I always take out a small cup of boiled water to dip the rubber ends in for a few seconds and that helps the last bit of stretch you need...

Kettle with a bit of water in bottom. Boil it hold pipe end in for a minute
Then little bit of light oil on fitting and push hard. Worked for me.

Just make sure you don't scald your self.

All great tips and simple, as i expected.

Cheers.

KY jelly works well. Don't ask me how I know

Agree with the hot water, then use 'white' grease, it doesn't affect the rubber at all. Always works for me.

If they are too tight surely they are the wrong size? Maybe?
