hi all, my fuel pump went on my mk2 mondeo so i bought a brand new complete bosch one for £150 and put it in.. but now my fuel gauge reads backwards, when its full its near "E" on the gauge and when its near empty its near the "F" on the guage, As i drive it every day i notice the fuel gauge going up as its using fuel

I cant work it out , it cant be the sender/pump as its brand new , im guessing its the gauge? Ive found a brand new one on ebay for my year of car is it worth buying it and seeing if the gauge is at fault?

I wanted to ask as i didnt want to buy a new gauge and not being the problem, many thanks.
