    I have a fuel smell on my 7.3 there is fuel ontop of motor in the valley of it. I have had the fuel filter housing replaced two years ago.. I think its this again.. wondering how hard it is to change out myself...

    Well there's a few fuel lines, and a few orings that you should look at first.
    Decrease the valley then run and check.

    The o rings on the valve that you open to drain the fuel filter may have rotted. That will let fuel in the valley. Very easy fix.

    fuel drain leaking, fuel crossover lines, and fuel filter housing itself are three of the main leak areas on top of the 7.3.
    the line going into the filter housing will also rub and develop a leak after 200,000 miles or so.

    Isn't there a valve coming off the housing that goes bad as well?

    I like running red fuel, it helps locating look leaks as well

    Yup, water drain, 30 bucks, two torx screws, and 10 min. Dorman part seems to last longer than oem.

    Big big fines.

    Been almost caught once in 2014. Been checked twice. I don't pay for fuel at all but sometimes, it more convenient to refill urself from transfer tank.

    i have only been checked once is 28 years on the pickup. came close 3 other times, but they flagged me past when the got someone in front of me with red fuel.
    i learned a long long time ago it just is not worth the chance of getting caught.
