Default fuel consuption after pump service

Dear experts
Have now owned two Pajero 2.8 TD, 1995 and have had the same issue with both. After a service (rebuild) of the diesel pump the fuel consumption has almost doubled.
Would anyone know how why this is and what to do about it?
Many thanks

The Fuel economy should be around 10 - 12 lt per 100 check that if over. Take the car back to the mechanic who fitted the pump and injectors. If you fitted it yourself check the pump timing. A rebuilt pump often uses the 11lt mark as it is now issuing correct fuel amount whereas old pump was loose and didn't pump correct amounts due to calibration being out. Also its a good idea to clean the inter cooler out if its full of oil residue performance will suffer. This site has plenty of info in "more power for your 4M40T"

If you don't mind, how much did you pay for a rebuild?
