Car is a '68 Cooper S, 1340 with a single HIF44 SU.  Started it up today for the first time in months, and noticed a fairly rapid petrol drip from the non-return valve in the brake servo hose.  I don't know if this is purely because I used a fair bit of choke to get it started, but I suspect it shouldn't be doing this!  Any ideas?

Thanks

Actually, further investigation seems to show it's dripping from the flexible fuel line above onto the vac hose.  Another ethanol victim, need to source some decent ¼" fuel hose.

Is it petrol?

 

brake fluid?

 

anything in it should be being pulled to the engine. There should be no way petrol can get into that hose if things are fitted correctly.

 

braked fluid can be pulled in if the servo has failed.
