Ethanol resistant Carb Seals

[Pablo110]

Hello Everyone,
is there a supplier of Ethanol Resistant Seals for the HS6 carbs on my Conquest Century. Yet again the Jet Tube seal has failed on one of the Carbs. Getting fed up rebuilding the Carbs every 18 months or so!

Regards,

Paul

Have you tried Burlen.co.uk?

Hello Paul,

A call to Burlen, may assist - I know they do the ethanol proof "stay-up" floats.

The other alternative is to use an ethanol proof combatant such Millers VSPe:

Thanks for the replies. Had a look at the Burlen Website, they do a complete Jet Bearing assembly which is Ethanol resistant. I shall be ordering a pair.

Regards

Paul

Hi what are the signs that the seals are failing as I may need to check my ones too thks

Any type of fluid seal that deteriorates will allow leakage - if your carbs leak or the fuel lines degrade you will see and small fuel.

If you examine seals that have been affected by ethanol their change of physical appearance and construction will be obvious to the eye. Ethanol degrades rubber and the seal becomes fragile when touched or in some cases ends up being a rubber pulp.

In my earlier post, the suggestions there will go a long way to keep ethanol under control.

I'd also add that all fuel hose on cars should now be at least R9 rated or better still R14. One of the best ethanol resistant fuel pipe you can buy is Gates Barricade; easily obtained via Moss.
