Air lock in fuel pipe - Vitesse Mk2

Recommended Posts

Hi, having sorted a spark issue I found the petrol wasnt getting through to the carbs and isolated the issue to an air lock in the pipe work under the car - Heres a simple way to remove the air lock without drinking fumes or petrol . A section of inner tube over the fuel intake and blow - this pressurises the tank and forces fuel down to the fuel pump - simples !

I wish I had thought of the idea . My neighbour saw me struggling and put me right

If the pump is working it has 2.5 psi output and an equivalent suck 

It should pull fuel ok to overcome an empty pipework 

So   this  sounds like the pump is sucking air in at a connection

Hi Pete you are correct , when we blew into the inner tube a leak showed where I had included a visible inline filter in the boot  - without blowing I wouldnt have found the air leak .

Just need her to fire up now

How very dare you!

But I think correct.
