Cavalier Fuel Cutoff

A friend of mine has a Cavalier 1.8 injection (on an M plate) and when he
goes around corners particularly roundabouts the engine dies. He thinks
it's a tilt fuel cut-off switch but he cannot find it anywhere in the manual
he has.

Can any one help?

Cheers

Not got one. Probably find that the fuel pipe pick up in the tank is to
high and need bending down.
