According to the repairpal estimator the price charged for the spark plugs is OK but the labor cost is high. Fuel filter parts price is OK and labor is a bit low. I do not know exactly what pulley was replaced along with the v-belt, the price could OK. The price for the injector service also looks to be OK. Over all I would say the price you were charged for these services on your 2007 Lincoln Mark LT were a little above what can be expected but not very much so.
