The no-pressure gravity feed lines from the brake reservoir to the master cylinders weep brake fluid.

Wouldn't call it a LEAK, never add fluid, but the lines are wet and slippery...its not moisture.

The original lines are SAE spec 30R6KX. Three are original lines, about 7 years old and on one of the brake master cylinders about 3 years old.

Doing a lot of r&r for other odds and ends, thought I would change out the lines, but only if the new hose will not WEEP through the wall.

OK, is there a SAE spec fuel line that is less permeable to brake fluid?

I have some replacement hose, labeled SAE 30R7. One piece is labeled "fuel vapor" "not for fuel injection systems" the other SAE 30R7 and is labeled "50 PSI Fuel/Emission".

OK, I guess both new pieces meet the SAE 30R7 spec as labeled, ie: they are good to 50 psi with gas, but what SAE spec line may be more resistant to having brake fluid weep through the side?

Thanks
