• Ford Fiesta - Fiesta tdci fuel leak 3 Aug 2016 (Forum)
  Hi, Last couple of days I've been smelling diesel through the fans when stationary and low speed. I had the injector seals replaced last year there doesn't seem to be as much fuel this time. The leak seems to be coming from the small fuel pipe into the top of the inject, the one with the little metal clip on.

  I have had 1.9tdi diesel from new, just filled the tank with disel which "leaked" over the garage forecourt. This problem only occurs when the tank is filled up and not when it is partially filled. I have had the seal on the fuel pump replaced but it hasn't resolved the problem.
• US Fuel Prices 5 Sep 2005 (Forum)
  Fuel cost graph on tonights channel 4 news showed a price of $1.75 a gallon on the day before the huricane had now risen to oapprox $2.50, still cheap by UK standards. Bought diesel today at 97.9p/litre, i reckon within 2 weeks it'll be over £1.00 which is an incredulous amount when not more than 6 months ago it was around 81p

• Vauxhall Corsa B (1993 - 2000) - 93 1.5 Diesel tank sender unit question 5 May 2008 (Forum)
  He thinks it could be taking in air from the top of the tank when the diesel level gets low. Borrowed a manual for a petrol version to see how to get the sender unit assembly out, and on the petrol tank, the assembly contains the fuel pump. The same plastic housing is in the diesel version, but we are just curious what is inside this as it doesn't contain a pump.
• Older diesel 4x4 recomendations ? 13 Sep 2007 (Forum)
  In the market for a diesel 4*4 5 or 6/7 seater with half decent fuel economy. Max spend approx 5K hopefully less. Wife loves the Discovery, horror build quality and rust puts me off. But can see the attraction otherwise. The 300TDI would be the one for us, but most examples high miles and corrosion everywhere.

  Following the demise of Asda offering a fuel card with points to be redeemed for future shopping bills (I bought more fuel, instead of food shopping), who now offers the best value scheme? As the Shell station near the Asda store price match, I have now started to use their card.
