So I bought a used D2 V8 4.0 and everything seemed fine. Generally good condition, 122,000 miles. The fuel gauge showed 1/3rd full so I went to fill up but could only get $20 in before it would not fill anymore, shaking the last drips in. Obviously the pump sender is faulty as it only went to 5/8th full on the gauge? So I reset the trip meter and after 173 miles today I went to fill up expecting to put 11 gallons in - I could only get 6 gallons in.

Any ideas anyone? I did think that the tank maybe be full of drugs! Not checked that one out. Otherwise I am getting 28mpg and that cannot be right. Faulty fuel filler neck perhaps? Seems unlikely.
