• VW Golf III diesel 1996 - No fuel going into engine 15 May 2010 (Forum)
  Hi there, I'm having problems starting my golf diesel mk3, and i've noticed that fuel is not getting to the engine. I checked out the fuel relay and fuse, the fuel filter and it seems that the fuel pump may be the culprit. I've been advised that it may be the lift pump, so my question is whow difficult it may be  to replace by myself?

  Hi all, I'm going to change the fuel filter on my Son's Mazda 6. I've located it but is it self bleeding like most diesel cars now or do I have to prime it/ fill it with fuel prior to refitting? As always your advice and guidance is much appreciated.

• Diesel fuel water treatment? 31 Mar 2007 (Forum)
  I drive 2 common rail diesels and wonder if I should keep up the practice of adding a "water treatment" at the end of each winter. I have noticed that the same company makes a dry fuel additive and a cleaner which claims to "demulsify" the fuel to allow the separator to work better.

• Water in fuel (intentionally) 31 Jan 2006 (Forum)
  In the case of diesel, water also reduces the tendency to detonate and significantly lowers NOX emissions. California is making an 80% diesel 20% water fuel available at commercial filling stations.
• Petrol v Diesel v Dual Fuel 12 Mar 2003 (Forum)
  Is there a quick rule of thumb formula for working out when it becomes more economic to go for a specific type of car. (Thinking high mileage) Diesels cost more, but do they depreciate less? Some petrol engines are very fuel efficient and not that far away from diesels. Will dual fuel always be as cheap as it is now and how much do they depreciate compared to the other two?

• Honda Civic - B10 Diesel 2 Sep 2022 (Forum)
  I was surprised to see that the standard fuel was shown as B10 whilst the Super grade was B7.  This led me to wonder whether there are likely to be any similar issues with this fuel on diesel vehicles  as there appear to be with the petrol version.

• Pug 306 diesel, fuel temp regulator 29 Jul 2005 (Forum)
  Hi, I recently had to replace one of the leaking o-rings on the fuel regulator in the fuel filter housing. This has now got me thinking about how it works and what its purpose is, and a possible modification. For those with a 306 diesel, it can be seen on the bottom left corner of the fuel filter housing where the fuel inlet pipe comes in.
