mel Posted September 21, 2012 Share Posted September 21, 2012 Abit of a strange one, but after having a leak (again) from the fuel filter on my 2004 D2 and changing it i was making sure all was ok by taking it for a run but on my return i felt all around it to check for leakage and the filter was hot. Is this right as i must admit i never noticed this before and wouldn't have thought it should get hot. ? Thanks Mark Quote Link to comment Share on other sites More sharing options...
Dave W Posted September 21, 2012 Share Posted September 21, 2012 It's pretty much as you'd expect, assuming your 2004 D2 is a TD5. If it's a V8 then you have a problem ! On the TD5 the fuel is returned to the fuel filter having spent some time in the cylinder head. It passes through a fuel cooler but that only takes the edge of it using the coolant system so it'll never come out of that cooler than the radiator. Fuel isn't returned to the tank as such so has a tendency to circulate between the high pressure pump, the cylinder head and the filter.
