• Pug 306 - Air in fuel system 17 Oct 2011 (Forum)
  After an hour or so of frantically trying to work out where it could be drawing air in (and hoping it wasn't corroded fuel lines) I found that the little white plug at the bottom of the filter housing was leaking fuel. I tried turning this but it just seems that it is not on threads so I can't tighten it.   I think that this is where the air is being sucked in, now I have a few questions.
• Ford Escort van N reg 1800 diesel - sluggish/bad fuel consumption 24 Jan 2011 (Forum)
  It just seems to me that something is just not fireing correct like in a petrol engine that is miss firing .Also my biggest concern is the drop in fuel consumption i used to get 475-540 to a tank now it is down to 360-380 . I have spoke to my local garage and the reply was it must be the fuel pump very expensive to sort out . Can a fuel pump make this happen i think it is something very simple that has been overlooked but i know nothing about engines so im useless.

• Mitsubishi Lancer (2008 - ) - New Mitsubishi Lancer - Why poor fuel economy? 18 Sep 2008 (Forum)
  At todays fuel prices thats an extra 390 gallons costing £2106, and we all know that will be higher with the speed that diesel fuel prices are increasing. So sadly that is telling me that I am probably going to be sticking to Octavia's (which are great cars .... but don't look like a 2008 Lancer) So what is with the poor (in comparison with VW/Seat/Skoda/Audi) fuel economy?
• What fuel consumption gaffs/efforts have you made 1 Apr 2008 (Forum)
  What fuel consumption efforts and mistakes, including purchase, have you made over the years?. 1) 1967 Mini van, fuel consumption (best) 38mpg on east coast run. Fitted a Mangoletsi ? Manifold modifier, which basically just seemed to do nothing except cut performance as it reduced inlet manifold diameter.
• Ford Escort (1993 - 2000) - 1998 TD - Delayed Turbo, fuel delivery problem? 3 Dec 2007 (Forum)
  When he came back the idle was unsteady, it was smokey, there was a lack in power, slow to rev, poor MPG e.t.c. I have changed the fuel filter, blead the fuel system, checked for air in the fuel system, cleaned egr valve, used injector cleaner in the fuel e.t.c. I have noticed that instead of the turbo coming in at around 1500-2000 rev's as it should, it comes on at 4000-4500 rev's, when this happens it runs like a dream until the rev's drop below 2000 rev's and then there appears to be no boost again.

• Fuel Filter on Back to Front! - Cavalier 30 Sep 2003 (Forum)
  I tried blowing water through the old filter in each direction, and it takes a lot more puff to get it through the wrong way. Question is, is the fuel pump likely to have suffered in 20k miles of pumping \'too hard\'?! Are there any other problems that this could have created during this time? And given that the fuel filter appeard fine (if back to front) is it worth keeping as a spare?
• If you really want to pick fault with company car 10 Dec 2001 (Forum)
  re looking forward to collecting a Peugeot 406 2.2HDi 136 GTX. If you allow your employer to provide fuel for private use in this company car, the Inland Revenue will include in your income tax affairs an annual ?fuel scale charge? of £3,620. In other words you will be taxed as if you received an additional £3,620 income i.e. the fuel provided for private use is worth £3,620 p.a.(£302 per month).
