fuel filter recommend change every 50,000 kil. fuel filter cost about $25.00. 1/2 hour for labour. use secondary field to expand question.
a fuel filter is very small repair, shouldn't cost any more than i have stated. if you pay more than, you are over paying. a fuel pump and sender combo should be at a minimum $250.00. labour to install about $250.00. shop around. find the best deal. clean fuel system every third or forth fill up. this will maximize the life of your fuel system components. recommend ethanol specific fuel treatment. it's the ethanol in the fuel that fouls up fuel line components. also never(if you can help it) let your fuel tank drop to 'e', as this will over strain your fuel pump causing premature failure. hope this all helps.
