Fuel strainer and fuel filter 306 hdi

[Welshy_Pete]

Nope, it's a tank down job to inspect or change really.

I was thinking it sounds like a lot of work just to change a one way valve when I can just do the fuel cap not so tight......

I thought so is that much of a job to take the tank down?

Some people say drill a small hole in the fuel cap or best just loosen the fuel cap slightly.

The fuel cap I tighten it right up then loosen it slightly to vacuum can work but no dirt get inside. This should be ok as long as the fuel tank not filled right up?
