Which Fuel Pump Gauze?

The pump I have has two different shaped gauzes that fit to the pump inlet.

Does it matter which one I use? The one that came off my old pump was the one on the right in the picture but has some internal plastic frame making it solid.

The one I've fitted is more of a flexable bag like on the Left in the picture, surely the inlet position is the inlet and the bag gauze shouldnt matter too much on style? Especially now i've lowered my pump??

Any advise welcome.


Cheers

The internal plastic frame is to stop it stucking the filter flat. I would use that one.

Hmmm sounds like I should use the one with the internal frame then. Weird that you get one in the kit without the frame if they do collapse...

Thanks for the heads up though
