Hi all. I was wondering if anyone could help. I have had the bus now for a few months and it is starting to grate on me this niggling issue. If the car is sat for any length of time it struggles to start. It turns over fine but sounds like for 5-10 seconds as if no fuel is going through and then boom it starts and away we go. It also cuts out if you apply some welly too when cold if your going up hill for example. Having spent a good wedge of money trying to get this fixed with no success at two mechanics (one being an MB specialist). Can you imagine how annoyed I was when I said to hell with it I'll have a look myself (I'm about as mechanically minded as a goat), took off the the engine covers (see pictures) and found in three seconds flat a seeping fuel line. Now doing some digging it would appear that these "plastic" fuel lines are notorious for failing as they age allowing air in which causes all the associated problems I've been experiencing ( it also suffers poor fuel economy 28mpg and major smokeage under hard acceleration). Can anyone help by answering the following? 1. Assuming there are o-ring seals in the leaking plug (close up picture) what size should they be when buying these from somewhere like Halfords? 2. I have seen on you tube a chap that claims that if you cut off the plastic pipe at the nipple of the plug leaving a little tip an 8mm fuel line can slip over with a hose clamp. Has anyone had experience of this? Can I use regular fuel line on the high pressure side or does it need to be this special plastic prone to fail crap? 3. Can anyone recommend a good mechanic in the harrogate area of North Yorkshire? I can't believe I've spent the best part of £600 on useless S.o.B's when I spent five minutes of my untrained eye finding this leak. 4. Is number 1 in the photo the fuel filter and number 2 the fuel pump? Do I have another pump/ filter back by the fuel tank?
