Mpg on a XUD

[Piggy]

it runs from underneath the fuel filter housing, across the injection pipes, to the back of the pump...

i had this only few months ago...it never idled once warm less than 1100rpm...it was jammed, fixed and now idles 850 when warm...but it affects fueling more than just idle

What does it start like? Could need a little more timing, a 306hdi gearbox helps as well, could easily bust 50mpg @70-80mph on a run in my old one and I'm not patient enough to really granny a car! At 50-60mph it didnt seem to use any fuel lol
