[Vwdiesel] 92 Eco Diesel is running... Bubbles or holes

[The President]

Am I naughty? [somewhere my forum signature is "I'm not here to help I'm 
here to Pro-Volke" !]

As far as I'm aware a good pump can pull so well [above idle] that it can 
produce bubbles that are in truth under vacuum; so they disappear on the 
other side of the lift pump. This can manifest itself with a partially 
blocked/poor fuel filter... I stand here waiting to be shot down :o)
Sorry,
Mark
