silicone petrol pipes

[oldbiker]

Just curious ????

I bought some of the silicone rubber stuff last year and I am not too impressed, I found that the ends where the jubilee clips go have become quite hard and nonflexible.

so apart from looking like good swag when new, what are the advantages of the silicone stuff over the braided poly or braided rubber rubber types????

I only ask `cos i feel that I was ripped and hope that somebody could tell me that there really is some advantage, and that I did not simply waste my money

Think you've been stiffed and not using silicone rubber of any quality. Decent stuff keeps it's flexibility and shouldn't harden/crack like yours as it doesn't really suffer age hardening and copes with much higher temperatures than most other alternatives.

Regular silicone hosing will be destroyed by petrol.

You need to use fluorosilicone hoses. However, even this usually is not rated for PERMANENT Fuel use. This year SamcoSport released a hose called, I think, Samco ProFuel. This is apparently one of the worlds first hoses, suitable for fuel use, permanently.

What brand of hose are you using? is it fluorosilicone? If you do have Samco ProFuel, I'd get in touch with Samco about your problems, as it's obviously not fit for purpose.

It's just tartiness, particularly on a bike where the engine is solid mounted and can't move around on its mountings like a car engine. The main reason people would fit it is to compliment the rest of the blue hoses in their engine bay.

Braided rubber hose costs pennies and lasts for decades. Stick with it.

Why fcuk with tradition to improve the chances of failure?

I only found plastic, rubber or teflon (Polytetrafluoroethylene PTFE) products were suitable for petrol.

If it's cheaper/lighter/better wearing then I would consider 'up-grade' but I wouldn't change for change sake.

I have never had any problem with the braided rubber OEM on any bikes/cars/trucks.
It will perish due to heat or UV radiation but years of use would earn replacement with similar.
And fuel lines subjected to heat in service require a totally unique set up.
I'm Confused.

If you're always taking the tank on and off, these things are pretty useful:-

i see this 'samco' pipe is nearly £70 a metre. i've had bikes that cost less than that FFS! as for the poster who reckons that this is the worlds first 'permanent' fuel pipe, i have a '77 XS650 in the garage with the same OEM fuel pipe it had when it was built 33 years ago..... how fuckin' permanent does it need to be?
