You can see the result of my 8-month battle with rigid fuel-line incontinence in the Whart have you bodged up today thread.

Always thought they put a spiral in a solid pipe to absorb vibration and expansion?

I think that's true. I'm not sure about expansion but I agree a loop is used to absorb vibration.

The early Austin 7s have a loop in the line between the scuttle-mounted tank and the carb. The later cars have a mechanical pump and a rigid fuel line without a loop, I guess this is because the pump and the carburettor are both bolted to the engine and therefore vibrate in unison!

I've no idea about the Lagonda engine (sadly). Perhaps it just doesn't vibrate. smile
