Petrol dripping out of vacuum pipe at dissy end

Anyone able to offer advice please

About 6 weeks ago I fitted a 1-2-3 distributor and the vacuum pipe run was a bit tight so today I finally got around to fitting a longer vacuum pipe.

But on taking the old pipe off I saw petrol dripping out of vacuum pipe at dissy end I’d run the car for a short time on choke before taking the choke off.

Petrol going in the dissy can’t be a good thing, I’ve no idea how long this has been going on.

What are the consequences of this and how do I stop it ? ?

Car is a '73 MG Midget

Route the pipe so it rises from the inlet manifold rather than falls. It's kinda hard to stop liquid entering a pipe that's connected to a tube with liquid vapour running through it!

Thanks for the reply

The prevoius pipe was just about on a rise going across the (top) front of the rocker cover cable-tied to hold it up

The longer pipe I've already put to raise well over the top of the rocker cover

Do Ineed worry about the petrol that already gone thro' the dissy?

No, that will just evaporate when it wants to.

Thanks for that Steve I'd thoughts of the petrol getting into the engineoil and causing problems somewhere

More of a panic/depression moment - tho' I've had them with my cars with justifiable reasons before

Just got to worry about that new unlocated ringing/rattley noise now frown
