Orange Posted October 19, 2009 Share Posted October 19, 2009 Coroded or punctured fuel line? Have seen it before along the chassis rail of a Discovery and could be as small as a pin prick, but under load it causes problems... Quote Link to comment Share on other sites More sharing options...

Possibly copper seals/washers on the injectors. If these are leaking the return fuel flow will carry gas bubbles from exhaust gases. A leak in fuel lines / filters will not induce gases - these lines are under pressure - they blow not suck ! It could of course simply be a case that your pump is on its way out Dave Quote Link to comment Share on other sites More sharing options...
