I have a constantly recurring problem, where my van seems to create an airlock that stops fuel getting through when parked up for a while.
To get it going again I seem to just have to remove the inlet fuel hose for a second, which then seems to allow fuel to flow again. I used to blow down the pipe, but it doesn't seem to need this anymore, if it did to begin with. Once when I took the hose off I heard a rush of air, as you would expect to hear when a vacuum has been released, which is why I use the word 'airlock'.
The problem is I can't seem to work out how it is happening or what to do to fix it. I don't hear a rush of air when taking the tank cap off when it happens, so it doesn't seem to be caused by the tank not being vented, although I haven't checked any pipes down there yet.

Has anyone else come across the problem? Standard 1.9DG.

Can we assume you have changed the filter,
made sure the fuel line is not kinked..
and checked the pump operation is all good?

HI Kev, thanks for the reply and yes, all three are correctly assumed.
The fuel pump was replaced with known good (and a few thou longer rod), the filter was replaced with new and the fuel line is routed well.

I think it may happen more frequently when the tank is low on fuel, but can't be sure. I wish I could work out wht it is, I'm baffled to be honest. Does anyone know if the non-return valve in the overflow/return system might have something to do with it?
